Starscream's lip curls a little bit, just slightly, as he's apparently unamused by Knock Out's cavalier, less than respectful talk about their leader.

"I'm happy to say he isn't," he says with forced cheeriness. Then he frowns, lifts a talon to scratch at one of the vents on the side of his face. "At least... as far as I know, he isn't." What a troubling thought. "I don't think you have any room to talk though, Knock Out. You've come up with far worse ideas yourself," he says with a knowing smirk.
