I still think Tamara won’t have a FTL identity. Just because she is with Neal, who people think is Peter Pan or a Lost Boy, does not mean she has to be a Peter Pan character. As for why she is allowed in Storybrooke, perhaps Neal trusts her enough and has the town make an exception for her.
I’m glad you brought that up! If she’s not a fairy tale character, then I’ll be interested in seeing if Neal already told her about his real identity or not. Either way, I suppose it still suggests that Neal really trusts & loves her.
