"She’s with her true love!"
I’m sorry, but can we just appreciate this scene for a second?
Kristoff has no idea what Hans did.
Kristoff has no idea of his intention, of his plan.
Kristoff doesn’t even know that he indirectly but conciously tried to kill Anna.
And yet here he is, ready to beat Hans into pulp, just because he knows that it’s his fault that Anna was stranded on the fjord, freezing to death.
