I heard somewhere that when Order 66 comes, he can't bring himself to harm a Jedi, so Obi-Wan sends him and some other clones who are like him with Ahsoka to Shili, and lived the rest of his life protecting Ahsoka. But that's just what I heard. :)

I don't know. I think he became Darth Vader's lead stormtrooper. Hm, maybe that does happen. I don't want Rex to go bad too, Anakin was heart breaking, but Rex? I hope he doesn't.

i heard he kills himself because he couldnt bring himself to killing ahsoka

I haven't heard much about what's going to happen to him. I think he'll probably go rouge or something like that because I don't see him going bad. I'm not as worried about Rex right now as I am for Ahsoka though. The season finale preview has got me worried about her for some reason.

I know, she looks like she could DIE!!!!!!!!!!!!!!!!!!!!!!!!!

Yeah, same here. If so I'll be really sad and might cry. I'm bassically Ahsoka, we're so much alike. I can't see her die, I mean, I'm gonna be her for Halloween. Anyway, who knows. I can see all of the other Clones killing the Jedi, but not Rex. Rex seemes diffrent. Anyway, the newest episode was great wish Ahsoka was there.

i wanna be rex for halloween

Well Ahsoka survived the finale, but I'm worried about season 3 for her. Maybe I'm wrong though.

maybe she graduates
