Professor Emil Hamilton quotes from Superman: The Animated Series

The fact that your body chemistry absorbs the radiations so readily, leads me to believe that you share with it a point of origin.

Superman

You mean it came from Krypton?

More than likely it is Krypton, or rather a small piece of it. 'Kryptonite' if you will.

Maggie Sawyer

Rudy, can you hear me? Did you find out where the bomb is?

[in Parasite's body] I know where it is, all right. But you still have to pay.

Maggie Sawyer

Sounds like... Garver!

Rudy?

[in Parasite's body] Sorry, Emil. I put Rudy on the back burner. You're cooking with Earl now!

Maggie Sawyer

What's happening?

The Parasite has somehow taken Garver's consciousness, not just his memories.

Maggie Sawyer

How?

Garver's intellect, his ego, his force of personality. It all must have combined to overwhelm--

What's it going to be?

Superman

You're still stuck here, Garver, and you don't even know what hospital you're in. If that bomb goes off, there's a good chance you'll go with it. Both of you. [gestures towards Garver's comatose body]

[speaking to Garver in his mind] Come on, man, what are you waiting for? They got you. Cooperate and they'll treat you real good.

Superman

You'll never get away, Garver.

Ah, the best laid plans...

What do you have against him, Hardcastle?

He's an alien. He has no allegiance, no jurisdiction. I don't trust what I can't control, Hamiliton, and I don't like what I can't trust.
