what does Ray say?

I watched G-rev last night and there's a sentence that Ray saids but I can't make out what it is.

The episode is when Ray, Kai, Tyson, Max, other teams are all at the tournament for the first time (its the episode when they find out Kai has switched teams and Tyson gets emotional about it)

Anyway, Ray saids something in his head like "So Kai... has switched teams as well" Anyone know what he saids after "Kai..." it sounds like "Kaijo" but that wouldn't make no sense. So anyone know?

Btw I don't know if this subject goes in this area... sorry if its in the wrong area
maybe there's a nice long dramatic pause?
I think it might be "So Kai ... you've switched teams as well."
"So Kai jumped ship too, huh?"

Sounds totally foreign the way he says it though.
Oh, its "jumped" It always sounded weird and I can necer make it out. Like the other day when I watched the match between Kai and Daichi I relised that Daichi saids "Kaister", which was weird to hear.

Anyway cheers for answering my question guys Joyful_3
