Olaf leads the rest of the way to Elsa's castle, and they arrive before long. Like Kristoff, Anna is stunned by the marvel that is the ice castle, and that awe reaction remains when Elsa, in a newly made ice gown, arrives upon hearing Anna's entry.
Elsa is initially shown to be quite happy to see her sister again, but her fears of harming her again soon overcomes her, and she orders her to leave for her own safety. Anna assures Elsa there's no reason to be afraid, but Elsa refuses to listen, wanting her sister to return home to Arendelle where she'll live her life freely just as she's always wanted. Anna refuses again, telling Elsa about the accidental curse and that she needs to fix it.
Shocked and disappointed in herself, Elsa panics, losing control over her powers again, and although Anna tries to calm her down, it's no use, and the powerful Snow Queen accidentally strikes Anna yet again, though this time, in the heart. With neither of the sisters noticing the danger, Anna continues with her persistence, despite Kristoff advising they should leave, fearing for their safety.
Elsa orders her sister to leave once more, but upon hearing another refusal, she creates a bodyguard to get her going. The snow monster, named Marshmallow by Olaf, chases the friends out and away from the castle, warning them to never return. After reaching safety, Kristoff notices Anna's hair turning completely white, and realizes it's from when Elsa struck her in the heart.
