I READ THIS FIC BEFORE, SERA!
Though, given, it was actually two fics—because Lisa telling Dean to go was in a different one.
I approved of this ep a lot. But not of Dean thinking Sam used the baby as bait. I just rewatched the bit with Sheriff!Shifter and Dean in the motel room (25:20 on the avi) and Sam was so not back to the room yet when the thing said, "I mean our father." Hell, he doesn't show up until about 15-20 seconds after that.
WHY SO CYNICAL, DEAN?
P.S. My icon is up for grabs if anyone wants to use it, just credit me, please.
