Anna, Kristoff, Hans, and probably entire Arendelle was unfrozen last episode, after 30 years. Anna said that Ingrid unfroze them, but why would she. She would have done it during the events of this episode, or during the events of last episode, but I don't understand why, I think it would be better for her plans if Anna and Kristoff stayed far away. Thoughts?
