Shaun Murphy

Shaun has "almost perfect recall," extraordinary and genius-level intellect and the excellent analytical abilities that allow him to make highly accurate diagnoses. He is highly perceptive and often bluntly voices these perceptions, such as noting that Neil, his superior, was "arrogant" on the first day that they met. Notably, Shaun was the only person in the entire hospital to suspect that Dr. Marcus Andrews would choose to remain Chief of Surgery instead of choosing a new one, resulting in Shaun winning the betting pool everyone created on the decision. During hospital scenes, Shaun's thought process is frequently captured in an overlay for viewers, demonstrating his eidetic memory. This shows that he is a highly visual learner. Over time, Shaun's unique visualizing process has become evident to those around him to the point that they have realized what he is doing simply by looking at him. After hearing a patient describe what Shaun looked like in "Trampoline" before he collapsed, Claire immediately realized what had happened without having been witness to it for herself. Shaun's unique diagnostic skills are noted by many characters, including Dr. Jackson Han who displayed prejudice against Shaun for his autism. Jared Kalu expressed fondness for it years after last seeing Shaun with Asher Wolke commenting that it's the highlight of his day to watch Shaun do it.

His autism is depicted as obvious to many of the people he interacts with. He displays several traits of his condition, including heightened sensory sensitivity, abnormal inflection when speaking, lack of interest in eye contact and heavy reliance on routine. Additionally, he becomes fixated on certain objects at times, most notably the toy scalpel that Steve gave to him. He insists on eating the same thing for breakfast every day: yogurt and a green apple except for Mondays when he has breakfast with Dr. Glassman at the hospital. He loves to eat chocolate chip pancakes with a glass of milk. While Shaun was clearly uncomfortable treating Liam (the first autistic person he met), his unique insight into the young man's condition allowed him to recognize that he was autistic and not psychotic as was originally believed, help calm him through most of an MRI and figure out what was wrong with him. He was also able to get Liam’s parents (who initially discriminated Shaun because of his Autism) to see that they had caused their son to get sick and they subsequently began listening to their son rather than unilaterally making decisions for him. When a buzzing light and the stressful situation caused Shaun to go into sensory overload and collapse into the fetal position, Morgan was able to get him through it by getting him focused on surgery and Park realized what was causing Shaun’s distraction and eliminated the source by smashing the light. When Shaun went into sensory overload again during a C-section, his first solo surgery, he was able to fight through it and come up with a solution to the problem.

Despite Shaun's troubled childhood, he maintains a generally positive outlook on life, choosing to pursue medicine in the hopes of improving the lives of others. However, he was wary of forming deeper relationships with people after the death of his rabbit and younger brother. Shaun is revealed to have a great degree of proficiency, if not fluency, in Spanish. He also mentions an interest in football in at least one episode. Among the things Shaun dislikes are pickles, mushrooms, anchovies, olives, garlic, mayonnaise, walnuts, Chinese food, bread with cinnamon, nuts, seeds or berries in it, the way coffee makes him feel, confrontation and direct questions. He has an aversion to physical touch unless he is the one to initiate it and/or it comes from people he is very comfortable with. After he started dating Carly, Shaun was comfortable with her kissing him, but not with holding hands and only liked touching one thing at a time. He is shown as being fond of cats.

As a result of his autism, Shaun has trouble with cognitive empathy (discerning why people are upset), but is fine with emotional empathy (being able to see that they are). This is something that he himself notes. As a result, he may make a decision that is rational and by the rules, but morally wrong or otherwise harmful such as taking away Dr. Glassman's license due to the rules dictating it while not understanding why Glassman was angry with him (though it was clear to him that he was upset). This is something Shaun was shown working on such as learning how to drive to make up for taking away Glassman's ability to drive himself places by driving Glassman instead. Another example is how he treated Lea after her return due to being hurt over her leaving in the first place which made Shaun rude and mean to his friend. At one point, Shaun advocated against giving a patient surgery to fix a dent in his forehead as the surgery was cosmetic and unnecessary. After hearing the young man's story, Shaun actually empathized with the patient and came up with a simple and ingenious solution that fixed the problem while also saving costs. Shaun came to feel he made the wrong decision as the patient suffered a complication that almost killed him, but Park revealed that Shaun's actions actually saved the young man's life as he had been planning suicide beforehand. Shaun's trouble with empathy and communication led to him telling a mother that her anti-depressants possibly caused her infant daughter's severe birth defects, something that it was pointed out that no other doctor would have ever said. However, Shaun's bluntness at times has proven helpful; he once pointed out a couple's doubts, causing them to confront those doubts and reach a resolution. Carly even stated that she found Shaun's bluntness and obvious care for his patients cute when they had first met, a contrast to many people who are put off by that bluntness. She and Lea have both also believed Shaun to be the most genuine and honest person they know. He’s even had patients ask that he talk to them because they know he’ll tell them the truth.

Shaun's communication issues led to him failing to catch the cues that Zack Cordell was angry with him at a bar, while further angering Zack when Shaun said that he doesn't like to be touched. As noted by Glassman, Shaun all the same showed mercy to Zack despite his cruel and violent actions which is extraordinary in and of itself. Even more extraordinary is that Shaun's statement that Zack was misdiagnosed before collapsing from his injuries led Claire to successfully replicate Shaun's thought processes to see through his eyes and save Zack's life. In doing so, Shaun made Claire a better doctor because of how he inspired her. According to Glassman, this is proof that while Shaun may not communicate as others do, he does communicate and is heard and inspires others. Shaun also inspired Andrews - who was once the most reluctant to hire him - to stand up to Han and fire him so that Shaun could be rehired by offering Andrews advice that Steve had once given to him. Claire even thought of Shaun as a role model on certain things and sought his advice on how to deal with her mother.

Another problem Shaun often has is with romantic relationships. He was immediately attracted to Lea when they first met, even though he did not know much about relationships and was rude and mean to Lea when she returned. After their relationship resumed platonically, Shaun had trouble adjusting to Lea having a boyfriend and showed signs of possibly being in love with her. Shaun appeared to have possibly moved on from Lea or was at least trying to as he decided to ask Carly out instead, getting coaching from Claire on how to do so. Despite his “disaster” of a date, Shaun had genuine feelings for Carly who understood Shaun on a level that most people don't due to having an autistic sister and as such, isn't immediately put off by Shaun's blunt and potentially hurtful answers that are given in the moment. As a result, after talking about their doubts and getting advice from multiple people, Shaun chose to continue his relationship with Carly by seeking out a more relaxed informal date that wouldn't be so overwhelming to him and had been described by Claire as something she greatly enjoyed when Claire was using her own dating experiences as an example. Subsequently, the two continued with more informal dates, but Shaun struggled with the effects of his touch aversion upon their intimacy.

After spending the night sleeping comfortably with Lea and having a brief meltdown over the potential of being alone, Shaun appeared to lose some of his aversion to touch. When Glassman comforted him, Shaun initiated a hug that he only broke because he had to go into surgery and was late. During the subsequent surgery, when the patient grabbed his hand hard due to the immense pain she was in, Shaun did not stop her and instead told the other doctors to allow it as it distracted the patient but to hurry though he is clearly uncomfortable, though this was likely at least in part due to how hard the patient was gripping his hand. Just before admitting his love for Carly, Shaun took and held her hand for a brief time despite his previous aversion to holding hands with Carly at all. He even took her hand again rather than the crossing wrists compromise he had had to use previously. He also completely lost his aversion to physical intimacy with Carly with their first attempt at sex ending due to Carly's hesitations rather than Shaun's.

Although he temporarily feared that he drives everyone away from him, he is grateful in having gained the friends he has. In particular, Shaun became close friends (even brothers) with Alex Park and, although the two have clashed professionally, the two choose not to let it affect them on a personal level. During the COVID-19 pandemic, Shaun even allowed the homeless Park to be his roommate for a time. Shaun also quickly developed a close friendship with Claire who proved to be one of the first people to understand and relate to Shaun, while Jared (despite not knowing Shaun for as long as his other friends) had faith in Shaun's abilities to the point that he specifically sought Shaun out for help years after leaving the hospital and had described Shaun as being the best to his client. He was saddened by Claire leaving, as well as supposedly with Jared’s own departure and Neil’s death. He was also pleased when Jared and Claire returned and has shared a very easy working relationship with them, quickly falling back into working together and bouncing ideas off of each other like no time at all had passed.

In the later years of his residency, Shaun's greater experience with patients leads to him becoming more visibly empathetic and less blunt, at one point only agreeing to deliver a bluntly honest diagnosis because Lim, as his boss, orders him to do so. Despite his initial reluctance to form personal connections with his patients, he became close with Tara (who had grown up like him, an outcast, and was able to get her to take gene therapy to help her) and Isla Liu, opening up to her about his guilt over Steve's death to help Isla with her own guilt. While Shaun admitted that it isn't terrible to become close to a patient, he still doesn't want to do it moving forward. His combination of empathy and blunt honesty resulted in his patient and his mother reconciling with each other, impressing Lim who stated that conflict resolution is an important quality for an attending physician. Asher Wolke (who was estranged from his family for years, his father in particular), jokingly suggested having Shaun help Asher and his father resolve their issues with each other as a result. Unlike Park, Shaun is unable to see young patient Nathan as anything more than a patient despite Park looking at the case from the perspective of a parent as well as a doctor. However, Shaun helps Park find a solution for Nathan that can be done in a single surgery rather than multiple ones. Shaun later displayed a moment of empathy for Nathan by wrapping his toy dog's head in bandages after the young boy had wanted the toy to undergo surgery with him in order to feel better. Although Shaun had earlier not seen the point in such a gesture, he did it on his own specifically for Nathan after Park had explained why it was so important to the young boy.

As a senior resident, Shaun was called upon to help train new residents, something that visibly made him nervous when it was first announced. At first, Shaun struggled with being a leader to his residents, causing him to make a number of mistakes (which Andrews was concerned about). This made Shaun refuse to continue training residents until Lim talked him into continue trying. Eventually, Shaun adapted and proved himself to be a capable leader and teacher who is greatly respected by Asher and Jordan Allen as well as Olivia Jackson and Ricky Guerin before they left the hospital. Shaun has developed a good rapport with his residents despite his initial struggles with Jordan and Asher both learning from him and supporting him as Shaun learnt from and supports them in turn. Jordan in particular proved to be good at working with his moments of uncertainty, even encouraging Glassman to learn from Shaun rather than their relationship being of Shaun only learning from Glassman. She even told Shaun after he made a mistake that she follows his lead because she trusts his judgment and the fact that Shaun made a mistake only makes him more inspirational to her.

In the later years of his residency, Shaun became more assertive and sure of himself, although sometimes this resulted in slightly disastrous results when Shaun argued with his superiors. He rather brashly accused Dr. Paul Nakano of making a mistake with his behavior getting to the point that Nakano claims that in Andrews' position, he would've fired Shaun. While Shaun turns out to be wrong about Nakano having made a mistake, he was correct about there being a problem and he stopped the surgery in time to save the patient. Shaun's intervention and solution of the problem earned him Nakano's respect with the older doctor going so far as to ask Shaun to join him in the surgery and then later tell him that it was nice operating with Shaun. While working with Glassman when most of the staff were affected by magic mushrooms, their differing styles in the operating room caused Shaun to go so far as to publicly argue with Glassman over the matter, leading to a falling out for a time and Shaun getting into trouble for his behavior. After Jordan urged Glassman to try to learn from Shaun, Glassman gave him the lead on a surgery after Shaun came up with an innovative solution and took the chance to learn from Shaun, rather than remaining in charge himself. In turn, Shaun tried to be more accommodating to Glassman's way of doing things during the surgery which Glassman appreciated.

Due to emotionally connecting so much with his colleagues, Shaun took it very badly when Lim was severely wounded and constantly disagreed over the best course of treatment. A large part of this was that Lim's situation reminded Shaun of Steve's death and his inability to save his brother and Shaun's guilt over it. The worse Lim got, and the closer Shaun was to losing her, the more irrational his behavior got, resulting in a breakdown. However, a vision of Steve urged Shaun to let go of his guilt over his death, reassuring Shaun that it wasn't his fault. Steve and Lea helped Shaun to focus and he was able to save Lim's life. The incident and Lea's unwavering support of him throughout it caused Shaun to only love Lea even more. He also told her that he's trying to accept that Steve's death wasn't his fault. Notably, during this ordeal, despite Shaun's behavior, his friends recognized that it came from his concern for Lim and (despite Shaun arguing with them and at one point completely going against Glassman's orders) they didn't hold it against him. Glassman went so far as to praise Shaun's save to Lim despite his initial anger and later told Jerome that Shaun was the one that they needed, not himself. After Shaun snapped out of it, Andrews, Glassman and Jordan trusted his judgment to the point that they followed his directions with a simple explanation of how he came to his conclusion on the issue.

As a surgical attending, Shaun proves himself to be an effective leader of his own team and good at dealing with his patients, both of which had been a concern that Andrews had raised while arguing against hiring Shaun as a resident, although Shaun still turns to his friends and mentors for advice. He had difficulties with Danni when she was a new resident and Jared when he became a first year again, while apparently forgetting that they were like how he was when he was new to the hospital. As a result, Shaun and Danni clashed several times and did the same with Jared initially, although Shaun and Danni were able to work together during Danni’s time on Shaun's team.

Although on the outside Shaun appeared to be unbothered by Lim ending her friendship with Shaun, he began manifesting strange behavior that worried Lea who believed that Shaun was more hurt than he let on. Shortly after Lim ends their friendship, Shaun kept clashing with Park by rearranging their shared office furniture before seeking privacy in an old storage room and shutting himself away. This led to Glassman accusing Shaun of acting childish and isolating himself like he did in high school and the beginning of med school. Shaun appeared visibly bothered about what Glassman said and whether or not he was right about how Shaun was behaving, he did genuinely appear to be bothered by having potentially caused his friend's paralysis and the fallout for it to the point that it literally keeps him up at night on at least one occasion. Eventually, the two make up with Shaun admitting that he's not sorry for what he did, but for the pain that it had caused Lim. Afterwards, Shaun returns to his shared office with Park and stops isolating himself, suggesting that it had been caused by his guilt.

When Lea got pregnant again, Shaun went somewhat overboard in preparation for the baby (even becoming overprotective of Lea, to her irritation), some of which was justified as Shaun and Lea had been warned by Lea's doctor that it may never be safe for her to get pregnant again after Lea's earlier miscarriage. Shaun's caution proved to be warranted as she experienced internal bleeding as a complication of her earlier miscarriage. Glassman subsequently credited Shaun's keeping Lea in the hospital for saving her life. With Lea's pregnancy now safe, Shaun lost much of his overprotectiveness and instead excitedly prepared for the impending birth of his son. Unlike with Lea's first pregnancy, Shaun lacked the clinical detachment that he'd had at first, such as Shaun referring to the first baby as just the fetus for awhile. After Steven Aaron Murphy is born, Shaun balances being a father and a surgeon, something that Lea fully supports him in, proving himself to be a good father.

When the hospital took on medical students, Shaun struggled with Charlie, a young woman with ASD who was inspired to become a surgeon by Shaun himself and thus idolized Shaun. Shaun's inability to work with Charlie led to him kicking her out of the OR and publicly berating Charlie at one point, causing her to file a complaint against him out of the fear that Shaun would keep her from getting into a residency program. Glassman explained to Charlie that, having been held to high standards, Shaun was doing the same with her. During a mass casualty event, Shaun continued to be harsh to Charlie until she was able to use her own experience with overwhelming situations to help Shaun through a tough moment. Afterwards, Shaun became the only doctor to take Charlie's concerns about one particular patient seriously, leading to the two working together to save the man's life with Shaun teaching Charlie in the process. Afterwards, Shaun admitted that he may have been wrong about Charlie and suggested that she may become an adequate surgeon and Charlie withdrew her complaint against Shaun for the time being. The two subsequently developed a better relationship with Shaun even seeking Charlie's advice about getting Steve tested for autism. Shaun later, in his own words, spoke fairly of Charlie to Claire, but wasn't overly complimentary, something that Claire suggested he work on.

After Asher was murdered, Shaun was apparently unaffected at first which Lea recognized might be his ASD causing a delayed emotional reaction to grief. At one point, Shaun forgot that Asher was no longer there and was greatly affected after receiving a gift that Asher had gotten for him, finally feeling his grief and calling Asher a good friend.

During a mass casualty event, Shaun shone as a leader, demonstrating how far he had come by taking charge of the hospital's response to the event while Lim was busy in surgery. Lim chose Shaun as he wouldn't let his emotions get in the way and later commended him for his performance under such tough circumstances. Shaun proved to be capable of making the tough and unpopular calls, forcing Jordan to abandon a fatally injured man who had saved a young girl's life to instead focus on treating the man responsible for the event and performing an emergency C-section to save the baby of a seemingly fatally injured woman, only to turn his attention to the woman and save her after having one of his insights that revealed the true cause of her condition. At one point, Shaun became overwhelmed when he had multiple people looking to him for answers all at once, but after Charlie helped Shaun to focus on one problem at a time, he was able to use his visualization skills -- similar to when he would figure out an answer to a patient's problem -- to find an answer to each problem.

After reuniting with Shaun when she returned to San Jose for treatment for breast cancer, Claire pointed out how much he'd changed from when they first met, noting that when they first met, Shaun was soaking wet and barely able to communicate and now he was a top attending and a wonderful husband and father and was extremely good at helping people.

When faced with losing both Glassman and Claire, Shaun obsessively devoted himself to saving them both, ignoring Glassman's wishes to spend the time that he has left with his family rather than trying treatments that will extend his life at the cost of his health. After finding a way to save Claire that the FDA wouldn't let him try, Shaun realized that he didn't need to save everyone like he had set out to do, just his friend. Breaking down into tears at the thought of losing her, Shaun was willing to sacrifice his entire career to save his friend's life, willing to accept the cost as long as Claire would live. However, Glassman took the responsibility upon himself so that Shaun wouldn't have to.

Shaun eventually accepted Glassman's passing and spent the remaining time that his adopted father had with him. Taking to heart the lessons that Glassman had taught him, Shaun would go on to create a foundation in Glassman's name to help others with neurodiversity who sought careers in medicine and kept Glassman's lessons close to heart, passing them onto others. Shaun's own career would flourish over the years, resulting in him becoming Chief of Surgery, a testament to Shaun's talent and leadership.
