Even if he hadn't heard tone of the other man's voice, Michael would have been quick to respond to the sudden stiff readiness William showed before he pushed up on his feet.

Michael doesn't follow him up, he understands the importance of letting William stand up for himself without someone hovering over him as backup, but he does silently thumb open the snap on his holster and let his palm rest on the butt of the gun. His knees part just enough to set his stance to take out the guy's legs if he doesn't draw a weapon.

If there's going to be a problem, he's going to be ready. God help him if he draws a gun on William Evans.
