Hear me out: I’m not saying Bigby did it – the existence and continuation of the Fables series (as focalized, initially, around him) is enough to clear him of our suspicion. What I’m saying is Telltale is setting us up for another frame-job.
“What’d I say? You want the Big Bad Wolf to take you away?” Toad threatens his son.
So far the game has been built around the idea that people are afraid of Bigby, afraid because they don’t know how much he has been tamed. Even our closest ally, Snow, is uncertain about who we are at our most basic element.
In “The Crooked Mile,” Snow asks Bigby if he enjoys it “when things go wrong” – other characters such as Gren or Holly have mirrored that same question. I doubt the developers have put this in as simple window dressing. The inclusion, particularly, of Snow’s questioning in Episode 3 and, soon after, the opportunity to kill Tweedle Dum have more significance that the overall theme of mistrust between Fabletown residents. The developers are building the narrative toward a plausible moment where someone like Snow, Beast, Holly or Beauty could believe that Bigby did killed those women, and they are doing it by showing people having doubts about his ‘goodness.’ The overwhelming narrative is that, despite a player’s choices, Bigby is violent and ‘out of control.’ This has to come back and bite him in the butt.
