Elle: Chemical accelerant could mean chemistry student.
Reid: Could also mean chemistry professor.
Elle: Mmm, I say student. You need self-confidence to lecture in front of a oom full of 30 college kids. Arsonists are socially incompetent. This guy doesn't go on dates. He doesn't go to parties. He doesn't feel comfortable in front of groups.

Gideon: Your girlfriend thinks you're gonna break up with her.
Campus Patroller: (stops smiling) You're kidding, right?
