Ah, so Agent Coulson was on Level Seven

That explains how he survived dying and everything.

*Slaps forehead*.

Can't believe I didn't see that one coming.

This new trailer will explain all. Or some. Or... well, it's pretty cool anyway, and the way they keep releasing a new one, slightly longer, every day, we should have the entire pilot up by the end of the week.

Props to the Beard for the new link.

You can read a painstaking overanalysis of the new trailer at Wired.
