My Theory of Elsa x Jack Frost:
Everyone on the internet right now seems to love the idea of Jack Frost and Elsa together. I agree- it's adorable! But I have a theory about how the two movies would actually cross over and I wanted to share it. Feel free to comment about it at the end.
Firstly, Frozen happens before Rise of the Guardians- even Jack's "birth" scene. Kristoff's character was based off of Santa (in case you didn't know). If we place them in the same universe, we have to assume since Kristoff is based off of Santa, he would be the life before North became a Guardian. This means that Jack wouldn't be alive yet. But don't worry! There is still hope for the ship!
When Jack wakes up, he almost immediately flies on the wind. Why does the wind come on demand? Is it because it's under Jack's power? Classic Jack Frost myths say no. He controls ice, snow, and cold (but not necessarily wind). Then, is it a conscious force? I say yes. That is the only reason that after only a few moments and small experimentation with ice would Jack be able to fly. But who is helping him then as the wind?
That's were Elsa comes in. When she died after a long life ruling as queen, it is possible that she would be reincarnated as an immortal force too- but instead as a force of nature since she had elemental powers before death, unlike the other Guardians. After being alone for so long, of course she would help him when he first "wakes up" and discovers ice powers of his own. After they both find out he can't be seen either- Elsa, knowing what isolation is like, vows to always stay with him so he would never be alone like she was. Even if Jack might not realize how lucky he is.
I don't know if North realizes the winter wind is the Elsa he knew in his past life, but I like to believe that he does and kept her company before Jack.
Tell me your take on this theory- all problems and confirmations. Didn't it blow your mind?
