From what I understand, Bigby never actually meets Faith. The "Faith" that Bigby meets in the first episode is Nerissa that is glamoured to look like Faith. There are a few facts that point to this:

• "Faith" (aka Nerissa) claimed she didn't know the Woodsman, even though the Woodsman knew Faith.
• When Bigby met "Faith" down the street, he said it "feels like we met before". This suggests that Bigby actually met Nerissa before the events of the game.
• The first time you enter Pudding & Pie you spot Nerissa pole dancing. She smiles at you for no good reason; it's the very first time you actually meet her (if I remember correctly). It's probably because she was happy Bigby took an interest in the case, and also because it seemed like he was investigating it properly.
• The usage of the same spoken phrases between Faith and Nerissa.

In my opinion the real Faith might have been dead before the game started.

• Faith was dead before the start of the game, we have been talking with Nerissa the whole time, who was glamoured as Faith
• It's the other way around- Faith in episode 1 was real, and the head on the stairs was Nerissa glamoured as Faith.


I already pointed out evidence to the first theory, now as to the second:


• One glaring quote that stands out at the ending was Bufkin recounting that Faith used to "hide her beauty to escape her kingdom". This hints that Faith has a history of disguising herself to deceive others. Unless Faith never glamoured herself to look like anybody else, why did Telltale find it so important to include this line in the ending?

• Episode 2: Nerissa: "They used to call me the Little Mermaid". Like the whole Faith disguising herself line in the ending, this initially feels out of place because there's no parallel line for Faith in the little montage inside Bigby's head (ex. Faith: "I need to tell you something" Nerissa: "I have to tell you something). Could this innocuous line from Nerissa mean that she literally no longer is the Little Mermaid i.e. a glamoured Faith?

• Another out of place quote at the ending is where Bigby inquires about the state of Faith's body only to hear that Swineheart is "running some tests". If that really is Faith's body and not say...some glamoured Fable that is meant to look like Faith, why would this quote be so significant.

• When Bigby attempts to find Faith using the magic mirror, he can't find anything. This is because the ribbon was blocking his powers. However, the ribbon has already been removed from Faith's corpse (she's been decapitated) so what is blocking his power? Is Faith disguised as another Fable?

I think Nerissa is Faith+glamour, at least that was my impression the first time I saw the ending, will watch again today.

hmm who is the dead Faith then? That dead chick cannot be glamoured because after a while the magic wears off.
