He always knows where the real Snow is at all times because of her scent. Seriously, comic Bigby would've known right away that the head left at the Woodlands at the end of episode 1 was not the real Snow. His senses and detective skills are way better than in the game. He generally seems like a more competent character in the comic, always knowing what's going on. So far, I've never actually seen him lose his cool and rage out like he does at certain points in the game. Bigby feels like a completely different character in the comics. I'm only up to issue #55 but so far, I've seen tons of differences, especially with Bigby. Bigby and Snow's characters differ from the comics, but because there is few years time gap between game and comics, I would consider it as character development I very much like the fact, that game is a canon with comics. I am really satisfied how comics dealt with Bigby - Snow relationship, and like Alex28 said, there is also focus on their personal life. Bigby, Snow and Rose Red (Snow's sister) are the very main characters, but there is also a lot of very important Fables which was never introduced in the game (and I hope they will appear in the next season(s)). A lot of big events happend there in that time. Comics are telling the story of Fabletown and shows what happend to the Fables during 12 years.
I enjoyed this game very much (considering it as my favourite one), but after reading comics I am truly in love with FablesĪs it was said … more before, TWAU shows only one case, only one story which is taking place in a time of few days or months.
