Kripke has enjoyed kripking the whole fandom from day one, so I'm sure he had a lot of fun with the Castiel fanficskripking with that particular episode *nodnod*

They just had to up the angsssst factor, didn't they?

As if we needed more angst, you know? Which, ok, maybe we do but that's not the point! Or yeah it is but still, Kripke, you genius bastard!
