Tidus does ease to the reassurance. Internally, if not immediately outwardly, but some of his own apprehension does ebb from his shoulders. But he doesn't get lost in relief, as Roland asks his question, and Tidus gives a slow single shake of his head.

"They wanted it so they could send us a message when they were ready. The train won't answer them, apparently - it just ignores them. If they knew about what Anan did to it, I couldn't tell. But, they probably just picked up its frequency, right? We don't have any way of contacting her back on there."

So there wasn't a lot to be concerned about with the radio. So Tidus hopes, though he wonders if there's a way of tracking them with that radio. But if there was - it'd be a problem when it became a problem. When being tracked by the Ministry wasn't what any of them wanted.

"I didn't have that message, you know? That Halo left. The one you've got." He says it with a nod to Roland. That long SCA message that Roland recorded once on his phone. "So they didn't hear it. ...I wonder why they never picked up you or Seto though. I was expecting it, waiting in there."
