He definitely isn't expecting that and his gyros shift to compensate, but then Rogue is reaching up, her arms wrapping around his neck and clinging there. Her mixture of laughs and cries is a strange chorus, but she radiates joy and pure relief, resting her face against his chassis and he has no inclination to move her. Instead, very carefully, he folds one arm behind her. Not too tight, not enough to pin her, just a slight pressure.

It is, Knock Out thinks, the most he's been touched in quite a while. He doesn't necessarily disapprove.

(He is, inappropriately opposite of her happiness, glad her powers did not work and that he remains kept to himself.)

But for the moment, he just appreciates the affection as it's given. "No, you won't."
