I think going back to the room of portals/doors makes the most sense. And although he may not be able to get back to the Enchanted Forest, maybe he can enter elsewhere to another world. I guess I am wondering how he got sucked into SB if he was in Wonderland trying to get back to the realm of the Enchanted Forest? I guess I just thought as a FTL character he was automatically included in the curse? But what if the characters from all those worlds/doors are included? Would it be only FTL characters that have been dispatched to other worlds or does the Curse include them all? What was it Jefferson said about them all being strung together and connected?
For that matter, how did Regina get back? Was there an Enchanted Forest door? Because they didn’t enter the room of doors through a door, but from above, didn’t they? Were they whisked back out by a whirlwind to her castle?
Ahh, more questions than answers I’m afraid.
