I want to know who a bunch of the characters are, and hopefully I'll find out in season 2.

Here's a list;

Henry's dad
Captain Hook.
Dr. Whale
Sleeping Beauty
Mulan
Peter Pan
Tinkerbell
Jack (beanstalk)
Baelfire
That creepy guy who's always sweeping the floor in the "dungeon" where Regina was keeping Belle

If there's someone who you can't wait to see, post a comment :)
