if you had seen the the trailer of episode 5 you will see that Snow is at the place where the witching well is and bigby' hair will look like he is a wolf , What will make him like that ?
Snow dies? Probably for some people at least.
COUGH Canon COUGH
But no, seriously, she can't die, this is a pre-quel to the comics.
I don't trust those teasers anymore. But if I guessed, maybe there is someone in there with her and he's there to save the day or something like that.
However, we are playing OUR BIGBY, in Canon it's a linear story without options, this is our story, with our own endings. (1 of which is most likely the comic's path).
Nope, I think all the endings have to be canon to the comics. Perhaps some Fables that don't appear in the comics (only those) may die depending on our choices.
Going by previous trailers, any trailer of next TWAU's episode have 0-15% of actually game moments. So that moment with Snow can easily not be in game.
