Headscratchers / Adventures in Wonderland

• Just where does Alice exit into Wonderland when she goes through her mirror and how does she travel back?
  • If we follow the rules of the books, there's a mirror in Wonderland that leads back to Alice's room
• Where exactly do Tweedledee and Tweedledum live? Do they just hang out in the woods day and night?
  • If we're going by the original nursery rhyme and Through the Looking Glass, then yes, they do.
