Warning: Spoiler Alert
Ahh, so that's what Henry wanted the Piped Piper's bone flute for ... blackmailing Joe Corbin into giving him the jar of stuff that would allow him to get his mom pregnant with a demon baby. I was kind of expecting that it would end up being something ... bigger? ... maybe, but as far as the mythos of the show goes, getting a way for Moloch to enter into our world is pretty huge a thing (it's pretty much the thing right now).
I don't know why I would have been kind of surprised to find out that Corbin had a family, but I was. The way that Jenny and Abbie seemed to take up all of his time (in kind of an obsessive sort of way) made me imagine that he didn't have any family, and that the two of them were it. But knowing that there was at least one son and (possibly) a wife/baby mom in the picture puts a new spin on things. Now, we've got to add neglectful dad/husband to the picture (along with manipulator and super secret keeper). And now it makes me wonder just how much of what was going on Joe and his mom knew about ... and if Joe's mom was still with Corbin when he died (or if she got sick of all of the secrets and bailed, cuz I don't get the feeling that Corbin would have shared everything with her, and she may have had the feeling that he had gotten slightly obsessed over something that she may not have thought was real).
I get the feeling that Irving is completely boned and that no matter what anyone does, he is going to be under the thumb of Henry for the rest of his life (and beyond). At this point, I kind of want Irving to just turn and start doing War's bidding, since it doesn't seem like there is going to be any chance for anyone to free him from the contract that he signed; dragging out the possibility of him getting free kind of seems pointless and slightly boring (not to mention that it would be someone that the writers of SPN would do, and they typically turn things like that into a complete yawnfest).
Speaking of SPN, I know that since I watch a lot of shows that have kind of the same themes running around in them, I'm going to see some overlap, but the fact that SPN had a Wendigo episode early in season one, I felt like that kid in "South Park" that kept saying "Simpsons did it" through the whole episode. There have got to be more things that they can branch out into that won't give me flashbacks to episodes of other shows.
