Is AWESOME. Super, super, super awesome.
It's like
Terminator Salvation meets Misha's Nip/Tuck meets
leonidaslion's Suite!verse. Did Kripke read Suite? I bet he did. I was half-expecting Sam to drag Dean by the scruff of his collar to wherever it was he was staying. And the McG connection was there. And Manny Skerritt!
I have only one complaint. Future!Dean looked exactly like present!Dean. I mean, come on. Heh, by the look of it we'd never ever get to see scruffy!Dean and scruffy!Sam.
And the end? I cried ... it was so Perfect. I can't ask for more. Well, maybe for the scruffy part but you can't get everything, can you?
I love my show. I really, really do.
ETA : And didn't this scene -
- remind you of this scene?
