Jason was the only one who didn't need the extra push! All he needed was directions (and probably airfare). Sure, he did the worst to start off, but even then he still tried to lead his dance crew toward the straight and narrow.
I know it isn't really important, but I hope future episodes address how Eleanor and Jason are supporting themselves in Australia. That's the sort of thing that will bug me. And even if they get some sort of stipend for participating in the study, Eleanor was in Australia for weeks before that and if I recall correctly she hadn't been doing too great for herself before leaving, so what's the deal?
And it's nice to see Trevor back, but yeah, it sucked how that promo gave it away before the episode was over.
