What I liked about the Meg element is that we finally got an inkling that there are various agendas at play in the demon world, and not all of them are consistent.

We saw a hint of that in Crossroad Blues, didn't we? I mean, the Crossroads Demon seems perfectly willing to cough up John for a crack at Dean's soul. But this was more confirmation, and now that Meg is floating around out there, I really hope we'll see more about it.

Unless it was just demonic misdirection!
