He doesn't react to the cutting accusation she hurls at him. Verbal abuse is nothing if not common among Decepticon ranks, and Knock Out had correctly anticipated she'd be upset at learning what he'd discovered. He hadn't really expected it to be over the not telling her part though.

Driver's door still hanging open, he rolls toward her a foot, then two, and stops again. "Rogue, you're close to hyperventilating. You have to breathe slower."
