Maybe Alice should have foreseen that she might get a callout in return to her own callout.. but alas, it seem she wasn't expecting it, since something about his words seems to take her off guard. Alice momentarily freezes, though her expression looks the same as ever by the time she looks back at Allen.

"What do you expect me to do other than sit around?"

You think she looks like someone who knows how to have fun, Allen?
