Despite my disappointment that this wasn't the return of Graviton that I thought it was from the preview, I think this was a pretty great episode . At last we are getting some meaty inter-character drama. And hey, at last they made me care for FitzSimmons and used them beyond half-unintelligible plot device-y sidekick.
I love Coulson and May's interactions - forget Sky and Ward, I'm a Mayson shipper (I don,t know if that's the real name, I just made it up)
Now, here's hoping we might get the return of a super-powered baddie soon. Or at least more arc stuff.
