Unless it comes down to the BF saying that she had to make preparations before the curse came and she sent some of fairies out of FL and therefore sent Tink out to England first kind of like Bae was sent to England 1st maybe this is the connection with Bae and Tink they both were in England perhaps together and wasn’t Bae kind of on his own for about 3 months could the missing 3 months be with Tink in England?
Or this is where Hook, meets Tink and takes her to NL for Peter?
