I think it does seem likely that the wand might end up being TB’s. So perhaps the other FGM got it when Tink is banished to NL? Then RH steals it, and TB gets it back, and as part of that Marian and baby Tamara escape the curse, but RH is left behind? Of course, then how did Tink get back from NL to meet RH?
There was one spoiler and speculation (not spoiler) that suggested that if Tink is the type not to let slights go (the spoiler) that it would be Hook (speculation). I agree with that, especially if we find out he’s seeking her out now to take them to PP’s camp.
He probably flirted with her and she’s P’O’d at him because he used her in some way, perhaps to get out of NL.
Sounds like she isn’t entirely on PP’s side either.
So I am thinking maybe Tink was not in NL when Bae and Hook first arrived, but she gets banished there later on, around the time Hook leaves NL. Maybe she is how he left.
