Frozen (Disney film)/WMG
Han's has no personality of his own, but rather reflects the people he is around.
As explained here
Anna is lesbian.
While Anna may appear to have male love interests this is in fact not the case at all.
Han's reflects whoever he is with, which means Anna was attracted to her reflection. Since reflections maintain the gender of the reflected person, Hans is female for Anna.
Kristoff is based on The Robber Girl who is female
If Anna had actually died, Elsa's blizzard would have expanded into space.
Either due to her fear of her powers becoming that much stronger, or because of her murder being akin to breaking open a floodgate.
Elsa is a Magical Girl
She even has a Transformation Sequence.
