Tidus takes a mental sigh of relief, and also an actual step back He could get between the pair as a precaution, but he picks a spot that gives Senku more room, puts his back to the rest of the train, but keeps him near Roland, if he needs to move in quick.

And what? To stop him? His mind is thrumming with confusion, this situation they're in. What's even going on...?

But he doesn't speak, not after the request made. Feeling like a moderator between the two, or more so for Roland than Senku. Lips pressed in a tight line, until-

'It's broken.'

"It's broken?" Tidus repeats, eyes widening. He may have seen those empty wrists, but not really taken in their meaning until now. "When? --The mission?"

When? It had to be right at the end, right? Or- did something happen on the train?
