Maybe that is why he got mad at Faith cause he though she was Red? In the bar scene he confesses that he wanted to rob her but then the wolf (Bigby) came (you know the rest of story). After the Woodsman took some action he though she was going to give him money but she didn't. So when he saw Faith he though it was Red? They kinda look alike to be honest....
If there is anything i miss let me know also sorry if there are any grammar errors.
