From TVovermind.com:
We’ll be getting new episodes of Once Upon a Time through the end of January, then it looks like the show will go on a short hiatus and return on February 12. In that episode, titled “Skin Deep”, someone breaks into Mr. Gold’s house and robs him. Naturally, Mr. Gold doesn’t want to sit idly by and let the authorities handle it, so Emma makes a point to keep an eye on him when it looks like he wants to get some justice on his own.
Meanwhile, Storybrooke will be celebrating Valentine’s Day. Without some significant others, Mary Margaret and Ruby will head out with Ashley (played by Jessy Schram, who first appeared in episode 4 as Ashley/Cinderella) for a girls’ night at a local bar. But it looks like their Valentine’s Day might be crashed. Will Ashley’s boyfriend ask her a very important question? Will David crash the girls’ night to talk to Mary Margaret?
Emilie de Ravin is also appearing as Belle in this epsode. We hear that Gaston is also making an appearance, but no word yet on the Beast. In this episode of Once Upon a Time, Belle trades away her freedom for a chance to save her town from falling victim to the Ogre war.
