I was looking over the choices of all 5 episodes and loads of people sided with Snow and let her do things and agreed with her. Like letting her go to the Trip Trap bar or burning down Aunty Greenleaf's tree. I feel like people did this in the hope of winning Snow's heart but after everything you do for her, their last scene she just ignores you.
I'm positive Snow knew Bigby was attracted to her. Snow wouldn't have succeeded without Bigby's help, but she needed him to bend his morals in doing so. My theory is that she used that sexual tension to get what she wanted. And it worked! Loads of people agreed and did everything Snow told them to do.
So in conclusion, Snow White is a manipulative bitch. imo.
