Stunned into silence at first, Grant just... looks at the Rocket, then at Chip burying their face in his shoulder, then at the Rocket again, admittedly torn between alarm over what Chip was off doing, relief that they're okay anyway, indignation at the implication that he hasn't tried to talk them out of this behavior before, and just... just sheer confusion. Just, generally struggling to process what the hell is going on right now.

That probably all contributes to how scattered his eventual response is. "Th-that's-- okay, well, thank you for not pushing them off, I... have talked to them about starting fights but this is not-- it's not a specific situation we've run into before!"
