Anna, I don't think that's a good idea. Not yet, at least. [Elsa fully intends to go back as soon as possible, but Anna... as much as she'd love to have Anna by her side again, she can't risk it.] Ingrid is there. I don't know what she's planning, but it can't be good. Whatever it is, I don't want you getting caught up in it.
