No blow-by-blow reactiony tonight, as I was far more concerned with mashing avocados while watching Show than tippity-tapping on my computer. But, I do have a few things to say...
I really liked this episode. I loved the humor, I thought the guest actors--especially the kid and the birth mother--were excellent, and, as usual Jensen, Jared, and Misha were awesome.
My take on the Anti-Christ thing is that Show brought it up because they had to. I think the entire thing about showing the kid having ridiculous power and then having him run away to Australia, where no angels or demons could find him, was extremely smart of Show to do. This way, they don't ever have to bring him out again, unless they really want to, and then he's available. It puts to rest the entire question of the Anti-Christ (while also allowing some non-anvilicious soul-searching on Sam's part, natch).
Also, I've read a lot of reaction posts all season about how Castiel should own up to letting Sam out of the panic room and keeping Dean in the green room for as long as he did, and I really disagree that Cas has anything to apologize for. The primary trait of angels is that they follow orders--except when they don't, and therein lies all the trouble. Cas was following Zachariah's orders (and, remember, he'd been newly--and seemingly pretty brutally--re-indoctrinated right before then), and, at that point, he didn't realize that Zach wasn't acting on God's orders. Cas had not yet been betrayed and he didn't have the capability to refuse Zach. He didn't gain that ability until he learned that Zach was running the show on his own. As it stands now, Cas is still an angel, though a rebellious one. He doesn't really seem to get culpability. I am not even sure that he's really being as judgmental or accusatory with Sam and Dean over the whole Apocalypse thing as we see it, because I don't think he relates to those emotions. That's a very human thing, and while Cas is clearly humanizing more and more, he ain't there yet. Furthermore, I think we've gone way too far, at this point, and that Show seems to be treating it as obvious that anything Cas did under Zach's orders isn't Cas's fault.
As for the whoopie cushion, the hairy palms, "that'll do, pig," Dean's "face," and all the rest of it, I LOLed. Hard.
In re: Action!Cas I only have this to say: *ahem*I won't worry 'bout goin' to hell
Long as I got my plastic Castiel
Sittin' on the dashboard of my car
*bows*
:D
Anyway, good stuff, Show! I approve! Two thumbs up! Would watch again!
