When a Hunt goes south, Dean takes desperate measures to save Sam. And it works. Dean doesn't care if Sam's grumpy about what he did – his baby bro is alive and well, so he'll take all the complaining that Sammy can dish out; but if Sam cocks a leg on the Impala, he reserves the right to swat him with a rolled-up newspaper...

Murders linked to sex conventions plus chance of ganking demons equals a job that Dean really wants to tackle. Sam isn't so sure, but Dean isn't thinking entirely with his Upstairs Brain. They can work out details later, right, because hey, sex convention! And if Cas is going to help out with the demon thing, what could possibly go wrong? Or has sexy just got scary?
