Well, the title sort of gave it away, but, as we watched Sam and Dean trying to trick Jack into the box, we all said, "Jack may be naive, but he isn't stupid.  Sam is so obviously lying and Dean is desperately furious. Jack knows them better than that. He won't actually get in the box. He's not that stupid." And then we said, "Nope, he apparently is that stupid."

We're glad the box was destroyed, anyway.

The final shot of Jack was fantastic.

I don't think Sam could have stayed in the bunker with Jack locked in the box there. What exactly were they planning on doing then?

A plan that was as ill-conceived as the decision to try to shut the gates of Hell:  impulsive, ill-conceived, and now making matters totally worse.
