Is Snow White that White ?
I can't help thinking that Snow White isn't that White...
She makes weird (almost agressive) faces when Bigby isn't looking at her, she only smiles or act like a nice person when Bigby is around AND looking at her (or talking to her).
In the butcher shop, the butcher shop's secret backroom to be more clear, you can see Ms. White on the blackboard... why would she need glamours or spells ?
When Bigby arrives to the Crooked Man's place, Tiny Tim says that he's been told that Bigby 'made pretty clear' that he was coming there, the only people knowing he was heading to the CM's place were Bufkin (come on...) and Snow.
You can go through every single scene featuring Snow White and see how weird she acts when Bigby's not looking. It feels like she's acting or something or at least trying to hind something.
During the fight scene vs Dee&Dum she doesn't look that scared by Bloody Mary and the Crooked Man, she only looks scared when it comes to Bigby fighting.
Nerissa said that Bigby should pay attention to people close to him... and as soon as Snow White comes in she makes the weirdest face and go away. Right before going she asks Bigby to not tell anything about their conversation to anybody... even though it's clear that she knows he'll talk about this conversation to Snow. MEEEEEH.
I think she loves Bigby but she's as crooked as the Crooked Man. Anyway she's suspicious.
Sorry if I made some mistakes but English isn't my native language, I'm trying my best !
