It felt like that the whole season and it felt like we really didn't get an answer, just more hints.
Episode was good, probably the most enjoyable for the season but I wish there was a better answers to the question for the whole season, I really feel like Coulsons thing was a cop out, like they didn't even give a damn that it was an aliens blood in their system? And it looks like they'll continue on with it in season 2 so it looks like they'll drag it on as much as they can, which I am not feeling.
But maybe that's just me.
