"Yeah, well.... Nothin' I can do about it." Like he'd said. All he could do is hope they found their own trains. He said as much to Sanzo soon after they met (which says a lot for the trust that he placed in him).

He doesn't even know what to say about it. He can barely talk about the tragedy.

"That's why I'm all fucked up lately. ...An' I guess all the other reasons I been fucked up. I asked Raven to get one of them dream catchers for me." Which is the most he thinks he can manage. Other than that, he's just waiting until he can join them.
