Actually, Regina was able to leave Storybrooke. She went to Boston, to adopt Henry. The only reason she never crossed the town line, in Season 2, was because she would loose her magic.

The Hook-casting-the-curse theory, is still plausible. He has his memories, can cross the town line, the Jolly Roger is missing, and seems to have a hole in his heart. Zelena could have come to Storybrooke, with her silver slippers.
