Piccolo and Cell in “Unfinished Business”

Piccolo

You know you made one critical mistake. You should've never emptied this city of its entire population!

Cell

Why is that?

Piccolo

Because as long as there are no innocent bystanders to get in the way, I'm free to fight you with the best of my ability.

Cell

So what's stopping you?

Piccolo

You know, that's a really good question.
