Student: Does it ever get hard, dealing with all that tragedy?
Agent Rossi: You know it's funny, some cases they end well so you can forget them. And some like this one, they become a part of you.

Agent Morgan: Have you ever heard of Ephram Saldovar?
Student: No.
Morgan: David Parker Ray?
Student: No.

Agent Hotchner: But we believe this particular killer grew up in an environment so adverse he never had a chance.
