Photos: Once Upon a Time's Winter Finale Lets Frozen Go, Lets It Go

Once Upon a Time will bid adieu to Elsa, Anna and Kristoff this Sunday in its winter finale — but if things get misty, remember: Conceal, don’t feel!

In the episode “Heroes and Villains,” Storybrooke picks up the pieces in the wake of the Snow Queen’s “visit,” leading Regina to make a difficult choice. Meanwhile, Hook’s fate hangs in the balance as Gold’s quest for power threatens everything he holds dearie.

Then, setting the stage for Season 4B, an Enchanted Forest flashback to an intrusion during Belle’s stay at Rumplestiltskin’s dark castle will wreak havoc in both the past and the future.
