Tom, was... unsure of what to do now. He'd always been so certain when entering a conflict, so now when he'd jumped to Kozue's defense, he... didn't quite know what to do. It wasn't likely that he would have to physically attack Kou. Once Reizo slipped in, Tom began to think about what might have gone down, and immediately switched to detective mode. Though some part of him worried physical violence may still be needed.
Max on the other hand, seemed rather certain. He had taken up position behind Tom and Maeko, but right next to Kozue. He wasn't growling, but his ears were back, and tail was straight out from his body.
