Marlin: Look, it's not whether I want to forgive him, it's whether I can.
Cobb: Is that what you keep telling yourself?
Marlin: Hey, you never abandon your partner.
Cobb: Look, I wasn't a cop during the storm Boulet, but I heard the stories of how cops took sniper fire for days. Or how their daughters were being raped. Not every guy that walked during the storm should be punished for the rest of their life.
Marlin: Like you said Cobb, you weren't there.
Cobb: No, I was in a prison cell killing a man...and you forgave me.
