Guess Who's Joining Elsa on 'Once Upon a Time'?

Hey, everyone, remember when Once Upon a Time gave us all a collective heart attack when they devoted the last 30 seconds of their season three finale to having Elsa from Frozen appear in Storybrooke? Raise your hand if you've watched that scene an embarrassing number of times since it happened. I know I have. But while the creators were frustratingly tight-lipped on where Elsa's storyline is going and even on who else from Frozen might be coming with her, they couldn't remain silent forever. TV Line has confirmed that Anna and Kristoff will be joining Once Upon a Time as well.

For those who have somehow forgotten, Emma and Captain Hook returned to Storybrooke after a fun little trip in the past and Emma immediately commenced with ruining Regina's life. Turns out, the woman that the Evil Queen (aka Regina in the past) was going to kill was Robin Hood's wife and by saving her life and bringing her to the future, Emma reunited Robin Hood with his first love and pretty much shot Regina and Robin's relationship dead in the water. While we were still reeling from that revelation, the camera panned back to the portal Emma and Hook had come through and revealed that Elsa, the Queen of Arendelle, was power walking into Storybrooke.

According to TV Line, Elsa will appear for a total of nine episodes in season four, which means there's a good chance that we're going to get another split season. To be honest, I'm not sure how I feel about that. On the one hand, had the Neverland arc of season one dragged on for 20 plus episodes, I probably would have screamed. On the other hand, you can do a lot more with Elsa than you can fit into half a season. How are they going to top her, especially in the same season?

The news also sets Elsa's appearance in Storybrooke as taking place after the events of the Frozen movie. In particular, Kristoff's appearance in Once Upon a Time is said to take place while he is adjusting to life at the castle — which means that he and Anna have already hooked up and are, hopefully, still very much in love. Maybe season four of Once Upon a Time will be as close as we get to a Frozen 2?

The breakdown for all three characters is as follows:

Elsa: The Queen of Arendelle, this late-20s/early-30s beauty long struggled to control her “chilling” powers and even unleashed upon her town an eternal winter during her coronation. Ultimately, she realized that the key to controlling her powers is love — namely, her bond with sister Anna — and now she is aware of the threat she poses if she were to lose control of her magic again

Anna: Elsa’s slightly younger sister is a fun-loving, fearless optimist who often gets herself into situations where she is in over her head, yet is able to triumph due to her resourcefulness and can-do spirit. She values her relationship with her sister above all else.

Kristoff: This handsome, hearty, salt-of-the-earth ice cutter spent most of his life alone (unless you count his reindeer). He has a sometimes-gruff demeanor that can hide his deep love for Anna and her sister Elsa. When we first meet Kristoff on Once, he is adjusting to life at the castle — including sleeping indoors for the first time in his life.

There's still no word on casting just yet, but if Elsa is aware of the threat that she poses if she loses control of her magic again and she's freely using her ice to shatter the prison she was in, then that just solidifies my theory that she's here for revenge against the Dark One. Rumpel had just better hope that he doesn't do anything to make Elsa doubt her relationship with her sister or Storybrooke might find itself buried in deep, deep, deep, deep... snow.
