Mike and Saul in “Full Measure”

Mike

Now when I say I'm looking for Pinkman, we both know why, don't we? And you pretending otherwise only wastes my time and serves to annoy me.

Saul

Look, Mike, there are rules to this lawyer thing.

Mike

Is that right?

Saul

Yeah! Attorney-client privilege. I mean, that's a big one. That's something I provide for you. I give up Pinkman, well, then you're gonna be asking, "Ol' Saul gives 'em up pretty easy. What's to keep him from giving me up?" Y'see, so, then where's the trust?

Mike

I trust the hole in the desert I'd leave you in.

Saul

Yeah, that's... an argument.

Mike

Saul, don't make me beat you until your legs don't work. Now tell me where to find him. You know it's the right thing.
