^Most fans however chose Movie!Jack Frost who's 18, so it's not out of the realm of plausability that a big brother/younger sister relationship could transpire and due to the fact Jack really kids (as shown in the flashback, in which he pretty much chooses to hang out with the children rather than people his own age).

That would just be if Jack stayed with Elsa since her teenage years. Any younger and the whole Westermarck effect is gonna go on if someone declares that Jack would be looking after Elsa when she was a kid. Since the Westermarck effect is basically reverse sexual imprinting, kid Elsa would be desensitized of Jack and not won't develop romantic feelings for Jack later in life, only familial and platonic ties would happen.
