Lindsay and Halstead in “Unfinished Business”

Lindsay

Would you spit out whatever you're trying to spit out?

Halstead

Okay. Maybe this last month I don't like being the guy you use to get a rise out of your father figure.

Lindsay

You wish I was using you.

Halstead

Oh, I'm serious. You have issues. You need to work them out. Work them out without me.

Lindsay

I repeat, we haven't done anything. And if you want to keep it that way...

Halstead

Hey, that'd be great.

Lindsay

All right, perfect.

Halstead

Fantastic.

Lindsay

You done?

Halstead

I was done long before this conversation started.

Lindsay

Really? Then shut up.
