The laughter might have died in her but it's still alive and well in him. His cackles keep spilling, even with her clearly accusing questions.

"Here? You mean at the Terminal from Hell??" Another bark of laughter. His shoulders shake with it. Oh, that's going to get him for a good long time later. "The same reason you're here, obviously. Flights are grounded. No one's going anywhere. I'm sure as hell not walking back to school. I mean, would you? Especially when this place is covering everything free."

There's no confirming or denying that he's followed her at all. He doesn't think he needs to.
