UPDATE 7/20. This was confirmed during the OUAT Comic-Con panel. We'll definitely meet Tink!
This really isn’t that surprising, considering how at the end of the second season, Hook, Regina, Rumple, and the Charmings were off to Neverland to save Henry. Perhaps Tinker Bell will be the dysfunctional group’s guide once they reach the island? Then again, it looks like — in true Once Upon a Time fashion — Tinker Bell shares a surprising connection to one of the regulars, so perhaps Tink is someone we already know! (Although, we can't see Snow, Regina, or Emma stepping into the winged role...)
We’ll save the Tinker Bell speculation for another post, but in the meantime, what do you think this connection could be? Sound off in the comments!
