Shannon Keene

Archetype: The troubled, imperfect parent seeking a second chance.

Defining trait: A contrast between her outgoing social personality and her inconsistent parenting.

Biggest flaw: Failing to provide Robby with dependable emotional support during his formative years.

Character development: Her rehabilitation demonstrates that she can recognize her problems and work toward a healthier life.

Overall: Shannon is a secondary character whose importance comes from the family instability that shapes Robby's early life. She is neither a consistently reliable parent nor a completely uncaring one; her story is about personal struggles, consequences, and the possibility of change.
