Rocco and Spike in “Unfinished Business”

How did you do that?

Spike

You're tense, I'm calm. You apply excessive force, I control that force through fluid motion. That means relaxing the whole body so that it could react instantly without resistance. You know, without thought. Do you see now? It means becoming like clear water.

Water?

Spike

Right. Water can take any form. It drifts without effort one moment then pounds down in a torrent the very next.
