Better Call Saul, Season 5

Mike:
There's one other thing we should discuss. Nacho Varga. He wants out. He's done everything we asked, he held up his end. I think it's time we cut him loose.

Gus:
I see no reason to give up an asset.

Mike:
Once Salamanca's dealt with, we have no use for Varga. He's the only guy they have running things up here. He disappears, the Salamanca operation falls apart.

Gus:
[pause] Varga stays. Better to control the opposition without their knowledge.

Mike:
You have a gun to his father's head. That doesn't sit with me. You want to keep Varga for the long run... I don't think fear is a great motivator.

Gus:
A dog who bites every owner he's had can only be disciplined with a firm hand, or... put down.
