ABC's 'Once Upon a Time' was at Comic-Con 2012 this weekend, and the creators and cast did some dishing. There will be some big reveals for the story, and now there's a new teaser that sets up one of the big bad guys of the second season.

The show comes from Adam Horowitz and Edward Kitsis, both former 'Lost' writers who were brought in to write 'Tron Legacy,' so hopefully the success of 'Once' has redeemed them.  'Once' was considered a risky and up against still competition and perhaps similar to NBC's 'Grimm,' so the show's success is something of a Cinderella story.

It looks like we don't have anyone from team Screencrush at the Comic-con panel for even more dirt, but Deadline Hollywood reports that the creators dished that Henry Mills (played by Jared Gilmore) will have his father revealed to him this season. They also provided this teaser trailer, which sets up one of the big bad guys of their second season.

And it's Captain Hook, who breaks into Mr. Gold’s (aka Rumplestiltskin) shop to steal back his hook-hand. And though we've recently reported on some additional casting for the show, the identity of who is playing Hook is unknown.
