Hotch: Answer this - when the bomb went off at the coffee shop and you were directly across the street, why did you leave her there?
Kate: You would only do that if you knew that she wasn't in danger.
Hotch: Because you had planted the bomb.
Kate: But you didn't plan on the gas line rupturing, which actually put her in danger. You just wanted to be a hero.
Hotch: Like Grant.
Kate: Except you're not a hero, Allen. You're just a coward.
Allen: Then why did I kill all those people? Huh? You think you have all the answers. Why did I kill all those people?
