Angel, Season 5

[Spike is poised to drink from the Cup.]

Spike:
Probably should've dusted you. But honestly... I don't wanna hear her bitch about it.

Angel:
Spike, wait. Wait. That's not a prize you're holding. It's not a trophy. It's a burden. It's a cross. One you're gonna have to bear till it burns you to ashes. Believe me. I know. So ask yourself: Is this really the destiny that was meant for you? Do you even really want it? Or is it that you just want to take something away from me?

Spike:
[pauses] Bit of both. [drinks]

Angel:
[lunges to try to stop him, but too late.] Spike?

Spike:
[drops the cup, stares at Angel, bewildered.] I-it's... Mountain Dew.
