Elsa doesn't see her at first. She walks in, calling out Anna's name, telling her of an appointment she has the following week.
And then she hears the redhead.
Anna is sitting on her former bed, crying so hard she sounds like she's about to be sick. She keeps coughing and Elsa rushes over to try and help; maybe to comfort or calm.
She recoils when Anna pushes her away and shouts, "Don't touch me!"
Anna repeats it, softer, and just beneath her sobbing, Elsa can make out a question.
"Why don't you hate me?"
