Thomas waited with all the patience he could muster (admittedly not much in this current situation), as this 'War' guy gave them the answers to the questions they sought. And it wasn't too amazing. The guy didn't know what their end goal was, had blind faith in this leader of his, said something about finding your own reason to fight, and unsurprisingly answered Ascot's question as Thomas expected he would. This Q&A session had pretty much been a waste of time at this point. 

And then his own question was answered, and he frowned. So basically, the guy was saying 'Trust me because I'm honorable, but don't trust me because that's the smart thing to do'? Talk about mixed signals, to say the least. This guy was still quite obviously a villain, even if he was 'a man of honor', so Thomas would continue to treat what he said with all the suspicion it deserved, until he could prove he was telling the truth in some fashion or other. 

"If I say no, will it make a difference," Thomas replied to the question of if they were satisfied with their answers. He could care less what the others thought at the moment, since aside from Belle's, most of those questions had simply been wastes of time, earning only evasions, enigmatic answers, and things that hardly inspired any sort of confidence in this guy. Well fine. Let him be like that. They'd defeat the Six Senses, then they'd go and kick their butts too. It wasn't like they had a reason not to, since despite helping them at some point along the way, their actions still screamed 'I'm evil'. He just needed to get stronger, and then he'd be the one delivering a lesson.
