Ford and bill

YOU HUSBANDS Prior to the fifteenth episode of the second season, The Last Mabelcorn, Billford was an obscure rarepair formed on the foundation that Ford and Bill definitely had a history of some sorts in the past.

The episode delved deeper into the past relationship of Ford and Bill, revealing they had once been friends and partners. Ford and Bill worked together on the portal (alongside McGucket who was left in the dark regarding Bill's presence) and Bill was allowed to move in and out of Ford's mind as he pleased. Ford clearly trusted Bill, considered him a friend and idolized him, creating an entire shrine to him in his study and modeling parts (such as the windows) of what is now the Mystery Shack after Bill.

Because of their past friendship and Ford's obsession with Bill, they have been interpreted to be closer than the show let on or didn't outright say. The notion that Bill and Ford were in a romantic relationship at some point was not outlandish and had plenty of ambiguous canon evidence, and thus the Billford community grew and converted many shippers overnight.

Appeal Billford is commonly interpreted as the two being exes, and either half is still in love with the other or bitter about their relationship's end all these years later.

Fanworks also depict younger Ford having a crush on Bill (such as blushing around him) and vice versa, whereas other works portray them in a loving, affectionate relationship (despite Bill's true plans). Billford shippers also tend to believe Ford was extremely distraught about Bill lying and betraying him, thus taking their breakup very hard -- afterwards, Ford swears revenge against Bill and promises to defeat him, whereas Bill would rather Ford join him (and possibly get back together).
