Greenaway and Reid in “Compulsion”

Greenaway

Chemical accelerant could mean chemistry student.

Reid

It could also mean chemistry professor.

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, he doesn't go to parties, he doesn't feel comfortable in front of groups. [Reid looks at Elle, realizing he fits the description] And of course he's a total psychopath.

Reid

Of course.
