Sentinel doesn't react to the joke. Partly because he thinks it was goddamn awful and not worth acknowledging, half because he just doesn't really laugh.

All he does is dim his optics and hum lightly when Proteus gets to work on his face. He doesn't even want to know how bad it is and... he really hopes Proteus doesn't notice the fist indentation either.

A groan escapes him. "If only I could fly..." and also not pick fights with .1%er miners but u know u know
