While it was certainly more detailed than thee previous one, War's answer still said basically the same thing, and offered no proof beyond his supposedly trustworthy word that he was actually trustworthy and not just lying like a rug to them all. So yeah, as he went on to answer other peoples questions, Thomas was basically done with this conversation. 

"Yeah, whatever. See yah, wouldn't want to be yah," he replied to the most likely evil couple with a dismissive wave as he turned to other things, showing how he felt on the subject. 

That left him to deal with other issues, such as Ascot swinging about from his near breakdown or whatever to some sort of motivation frenzy, deciding that now would be a good time to recognize that he was the person who was supposed to be in charge, which was about dang time, and at the same time offering suggestions for 'roles' for everyone. Joy.

"Thanks, but I think considering what we're doing, assigned 'roles' aren't the best choice. We've gotta be flexible after all, rather than being shoehorned into positions. As we've seen throughout this trip, there's a good possibility we're not going to be traveling together all the time, so specializing like that would be a bad idea,' he replied, thinking of it from a standpoint of moving forward, when they couldn't expect to stay together for the rest of this quest. 

Asked what to do as well, he reiterated somewhat what others had thought or outright said. "For now, we get the Sign, wrap things up here, and then get going to the next world. Unless someone wants to stick around and see how much of stomachache they can get from all this candy." So yeah, maybe he was playing a broken record, but it wasn't like there was much else to be gained by sticking around, unless they planned to stay for a day or two so he could learn this new magic of his.
