Dollhouse, Season 2

Adele:
Good news on the coma front?

Topher:
Uuuhhhhhhh... yeah. Good news is that he's in a coma.

Adele:
I beg your pardon?

Boyd:
Just show her what you showed me.

Topher:
[Shows Adelle a brain scan] This is a brain. A healthy brain. Frankly an... overly smart brain... it's my brain. And this is Terry Karrens' brain. [Shows Adelle another brain scan] See these dark areas? How they extend all the way out to here? You know why that looks like that? That's because Terry Karrens doesn't use that part of his brain. And that'd be where you find stored such things as empathy, compassion... an aversion to disemboweling puppies. Basically, this is what some of your more famous serial killers' brains look like.

Adele:
You're quite certain of this?

Topher:
Certain enough that I have serious ethical problems trying to wake him up.

Boyd:
Topher has ethical problems. Topher.

Topher:
Heh. Way to land it.
