Once Upon a Time spun its own tale of Hansel and Gretel this week, while introducing a mysterious stranger to Storybrooke, someone who will clearly play a role on next Sunday's episode.

It's titled "7:15 A.M." and ABC is teasing it with a synopsis that reads Mary Margaret and David will "continue to grapple with their unrequited love," while Emma and Regina wonder about the new guy in town. Off in fairytale world, meanwhile, Snow White will have a difficult time with Prince Charming's wedding date looming.
