Addison: [to patient's parents, who is brain-dead but pregnant with a child] The problem here as I see it, is you want to use your daughter’s corpse as an incubator. That’s the problem!
Derek: A little sensitivity would be nice here, okay? (Addison looks at him in disbelief) They love their daughter. They don’t want to let go. Alright?
Addison: What they're doing is not about love, Derek! It’s- it’s- well, it's like you.
Derek (suddenly angry): Excuse me.
Addison: Like how you pretend to love me, but really you're just using me to fill some need you have to be a good guy.
