Explain this a little more? I feel like I'm missing something.

He said that the time travel weakened him. Being cut off from heaven, one assumes he doesn't get recharged on his powers, so two time-travel trips might have worn out a lot of the power he had left. I don't know that's what's gonna happen, just speculation/curiosity.

Oh, so when you said "done deal," you meant he might be completely human now, yes? Got it.

I had forgotten.

I have forgotten so much--and then I watch only 20 minutes before I leave for work and I'm tempted to read up on the episode before I get home. Must resist...but I have to admit...other than seeing Sam process his loss and Dean markedly not, this one doesn't grab me so much.

Since resting in 1978 let him be able to travel back to 2010, I'm at least hoping he can recharge that way. I understand why he can't be tossing around his full mojo, but I don't want him at zero yet.

Wait till you see the end. The MOW is strictly a vehicle for Winchester issues here, true, but the very end of the episode is worth it for me.

Wait till you see the end.

TORTURE.

Which I guess is only fair.

Check out these from London: here and here. No spoilers.

Dude, that's a hell (NPI) of a marketing campaign. I saw that Misha did some in-character UK TV promos encouraging people to track some sigils or something down to help the Winchester brothers out in his quest.

They went all out.

Okay, now to finish watching the episode.

so freaking cool!

Oh, Dean! Baby!

::sniff::

Is this the first appearance of Dean's single manly tear, resplendent in its crystalline perfection, sliding down his chiselled cheek?

The manly tear, maybe. He was definitely crying in the season ender for S1, though. I can't think of another time before that, though.
