I think we may get the answer to this question very soon. One of the sneak peeks for this week is of Regina trying to convince Jefferson to make one last trip out of SB to retrieve something for her in FTL. I think we'll see how he travels between the two and whether FTL still exists after the curse was enacted.
Wait… we already saw this episode…..
Oh, I misread that! I thought you were talking about when Regina convinced Jefferson to take her to Wonderland to get her father. 😆
I haven’t seen that anywhere in promos, but wow! That really will answer a lot of questions!!!
