She was absolutely precious. She had been very badly burned on over 90% of her body, and was obviously still recovering. Still, she was laughing and smiling, and wearing her glitter-bow Minnie ears.
So all the characters took a picture with her. Dale even kissed her hand and gave her his arm like she was a princess. She hugged all of the characters individually and kissed their noses (some, like Dale--who couldn't get enough of her--more than once) and told everyone--separately!--that she loved them very much. Dale, of course, had already fallen in love. How could he not? She was beautiful. As he had to leave, he longingly waved good-bye for as long as he could see her, then heaved a great sigh, and dutifully (for a chipmunk) went back to work.
The only thing he regrets is not learning her name.
