It's Cold in Storybrooke!

It's less than a month before things are about to get real chilly up in Storybrooke, and you can now watch the first promo before it airs in primetime tomorrow night. The season 4 teaser, courtesy of The Hollywood Reporter, features Elsa (Georgina Haig) talking a little walk through Storybrooke as characters like Rumplestiltskin, Captain Hook, Prince Charming, and Snow White look on in disbelief at the town's latest arrival. Judging by their reactions, this climate change is not exactly welcome. Watch the promo above, and get ready for your most recent Disney dreams to start coming true.
