I don't know what a Maine is, so I'll take your word for it. But I've definitely heard of the Enchanted Forest. We have one of those, too. But Storybrooke sounds like a cute little town name. I'm from the United States Of Aurdon. It's what they called all of the kingdoms collectively after Beast merged them. Though where I'm from originally is the Isle Of The Lost...which is the prison island where they sent my parents and all the other bad guys.
Huh. So that would technically make Evie your son's alternate reality sister and your step-aunt. Weird. I'm not going to think too hard of that. The alternate world thing makes my head hurt.
