Oh, the classic Jack and Elsa paring.

Well, sorry, I don't ship it.

Jack is suppose to represent not only snow, but also fun and childness. I don't think he really mature enough to actually fall in love. And I don't think Elsa would date Jack because of those reasons. She's potrayed as very mature, and although I understand that she loves her sister Anna, but that's in a completly different way. Siblings you learn to deal with, but your significant other you can choose.

Not saying I'm anit-Jelsa or anything, just simply that I don't that they'd work well together.

Not to mention, even besides Jack being the image of childhood, he's kind of immortal and Elsa's not. If they did date, first Elsa would have to believe in him, and second, she would eventually die and Jack would be left alone with a broken heart.
