[With an exaggerated huff, he addressed Iwaizumi, unable to let that remark slide] You have a nasty habit of butting in when you're not being addressed. Can't you shut your mouth for even a few minutes? [So much for trying to be mask his dislike] No one asked you. [Maybe this situation shouldn't have bothered him as much as it did, but Ann was fraternizing with the enemy and had been for how long? How could she stand the sight of this loud mouthed oaf. It likely also didn't help that both himself and Ann had engaged in their own semi regular exercise. It was like Iwa was intruding into his territory...]
