Watch Sneak Peeks of the Once Upon a Time Season Finale

By Lisa Weseman | May 11th, 2014

This week, Mary Margaret and David celebrate the naming of their son at a coronation in Granny's Diner, while Emma and Hook are pulled into Zelena's time portal and find themselves in the Enchanted Forest of the past. But in their quest to discover a way back, they must be careful not to change anything or risk altering the lives of their friends and family — as well as their very own existence.

Check out these sneak peek videos from "Snow Drifts" and "There's No Place Like Home," and tune in SUNDAY MAY 11 8|7c for the two-hour season finale of  Once Upon a Time.
