I also think it was Bae in the city, but I’m beginning to suspect that Jefferson sent the note. Did anyone else notice that on the wall of the city apartment there was a sign that said “Hatter”? Sounds like a clue to me!
GOOD IDEA but I do not think Jefferson had contact with BAE…. still think it was the Blue Fairy… for reason above. Jefferson was fixated on his daughter…. there was no indication that he knew about Bae or Rumple at any time.

Now that I think about it, I think you’re right. The Blue Fairy makes more sense than Jefferson for exactly the reasons you gave. I was just really struck by that sign in the apartment. Of course, it may be a red herring or it may represent some more indirect connection with Jefferson that will be revealed later.
