Elle Greenaway:
Chemical accelerant could mean chemistry student.

Dr. Spencer Reid:
It could also mean chemistry professor.

Elle Greenaway:
I say student. You need self-confidence to lecture in front of a classroom full of 30 college kids. Arsonists are socially incompetent. This guy doesn't go on dates, doesn't go to parties, doesn't feel comfortable in front of groups. [Reid looks at Elle] And of course he's a total psychopath.

Dr. Spencer Reid:
Of course.
