Catherine and Warrick in “Bully for You”

Catherine

So how's your new toy working out?

Warrick

It's been downsized.

Catherine

Bummer. I know how you wanted to see that thing work.

Warrick

Well, it's the same difference, really. Air is drawn into the last tube the chalk absorbs the chemicals from the air. And mass spec will break it down at the lab.

Catherine

So why did you need the expensive one in the first place?

Warrick

'Cause it was cool. (Cath smiles at his honesty)
