Elsa: What kind of sorcerer for this character?

[Puxido]

I was thinking, if somebody wanted to make Elsa from frozen in pathfinder, what sorcery domain should they pick?

Wild Magic, because sometimes you might shoot your sister in the heart with magic ice by accident. EDIT: I am dumb, I thought this was a 5E question.

Elemental (water) seems like the obvious choice. The Advanced Player's Guide has one called Boreal that might be worth looking into.
