As Isao had just sort of plopped down on the floor by the couch, he leaned against the arm and let out a quiet sigh. His decision back then wasn't anything he regretted. Had he the decision to make over again, he still wouldn't have chosen to just give everything up like that. In fact, he had remembered trying to get them to think of another way around things to begin with. He would never make any move that didn't feel right to him, even if it meant he was in the wrong. And... well, obviously he wasn't that far from wrong. Though it wasn't for him to say that things would've been different if they had all made the decision to fight. And he would be the last person to say that there wasn't some good in what happened, too.
Either way, he had absolutely no intention of apologizing for his behavior back then, but he did nod in some sort of agreement and perk up a bit with interest at Renju's comment. "Like chipping away at their infrastructure before facing them head on?"
