Anna is freezing solid after Elsa accidentally hits her heart with her powers. Hans turns out to be a bad guy, but his attempt to kill Elsa is foiled by Anna who steps between Hans and Elsa in the last moment before freezing. Her frozen body stops his sword. Elsa cries since Anna sacrificed her life for her. But, since Anna showed an act of true love for her sister, she thaws. Elsa realises that true love is how she stops the eternal winter. So, she unfreezes everything. Anna kicks Hans for tricking her. Then, everyone is happy and Anna and Kristoff become a couple.
Revealing mistake: When Anna and Hans are dancing in front of the lighthouse, we don't see the shadow of the railing or the ground they're standing on.
Trivia: In the scene where Anna is outside the gates during "For The First Time in Forever", you can see the backs of Flynn and Rapunzel from "Tangled".
Chosen answer: "It doesn't have to be a snowman."
