Kristoff really isn’t expecting Anna just now. He wants her there more than anything, of course and he’d even been imagining her voice and for a moment the actual Anna and the Anna in his head are kind of melding together.

However, when the real Anna says his name, Kristoff turns and his feet move before a thought even fully forms. His arms wrap around her and lift her off her feet. “Anna! You’re here,” that alone makes a lot of his concerns ease and disappear. Sven is going to be relieved too.
