Ben 10: Alien Force, Season 2

Ben Tennyson:
('spots the teleporter pod station) There it is. Come on! (looks back at Reinrassic) Not the ten paces behind thing again.

Reinrassic III:
Go home, Ben-Ben Tennyson. I shall remain here.

Ben Tennyson:
Did you hit your head or something? There's the teleporter. We can finally get off of this sand trap of doom and get back to our lives.

Reinrassic III:
I have spent too long with you Ben-Ben Tennyson. And have therefore myself become contaminated.

Ben Tennyson:
Contaminated?

Reinrassic III:
As clearly evidenced by my uncharacteristic behavior. Risking my own life to save you, a lonely human.

Ben Tennyson:
Reiny, what you did was a good thing.

Reinrassic III:
I have obviously become infected by your mongrel influence, and am now myself unclean.

Ben Tennyson:
But even if I believed that was true, why stay here?

Reinrassic III:
In self-imposed exile as it should be. For I can never return home, or anywhere. I could infect the rest of my kind. The only honorable choice is to remain here.

Ben Tennyson:
No!

Reinrassic III:
(proud of his race) Because all lesser beings other than pure unadulterated Highbreeds must be expunged from the universe... including myself.

Ben Tennyson:
I thought I had gotten through to you. I thought you had changed.

Reinrassic III:
This much is true. I have changed. And now, I must pay the price.
