Anna nervously giggled, unfamiliar with speaking with others, especially others who held the advantage of knowing her identity. He was still as handsome upclose as he was from afar, and after the initial giggles, Anna coughed, covering her mouth with her fist. "H...H...Hi there...Hans, you said?" Anna, in contrast to how well she spoke with Elsa, was stuttering, nervous, but still smiling, her eyes wide. She was blinking rapidly, a nervous habit of hers. The nerves only increased, followed by a blush, after Hans kissed her hand. A real gentleman, like in the movies she enjoyed as a kid - and still to this day. "Y...Yes, I'm An...An...Anna. Nice to me..me...meet you. Ha...Having a good time?" 

She figured it couldn't hurt to make conversation. It might help with her nerves.
