But why would he say that about nacho?

Nacho wasn’t being feed or worked for him. He was being forced and threatened, where he had no choice. His father’s life was on the line.

When Mike asked him, Gus said no, he could still be of some use to us. Mike put seriousness in his tone and asked him again, and questioned the purpose of it. Gus paused, stared at him and then said that.

Maybe it did relate to nacho, but somewhat directed to Mike as well.
