Are you ready to say goodbye to Frozen on Once Upon a Time?

Now that the Snow Queen (Elizabeth Mitchell) has been defeated, it's time for Frozen's Elsa (Georgina Haig), Anna (Elizabeth Lail) and Kristoff (Scott Michael Foster) to go home to Arendelle to defeat Hans (Tyler Jacob Moore), who has conquered the city.

And Elsa doesn't even know that her home is in peril! Hey, to be fair, so much has been going on lately in Storybrooke, so it's not like Anna and Kristoff have had a chance to tell her there's another crisis brewing on the homefront.
