One of the breakout hits of the 2011 fall television season was “Once Upon a Time,” ABC’s show starring Ginnifer Goodwin, Jennifer Morrison and Lana Parrilla about fairytale characters trapped in the real world due to an evil queen. The show went on a brief hiatus during the winter holidays, but now its back and in full force this Sunday at 8/7c.

TVLine has a gallery full of sneak peeks of the latest episode titled “7:15,” in which Prince Charming (Josh Dallas) is about to get married to another princess in the fairytale world and in the real world, Mary Margaret (Goodwin) is trying to get over being in love with David (Dallas). Later on, we will also get a full backstory on Red Riding Hood (Meghan Ory) and how she fits into this engrossing tale. Other new things to the series include more on Rumpelstiltskin (Robert Carlyle) and the appearance of a new stranger to Storybrooke.
