When Dean and Castiel reunite at the bunker, Cas has a nasty case of pneumonia and Dean takes care of him. (Slight AU set early season 9 in which Ezekiel healed Sam without possessing him)

What's Sam really doing all that time on the computer? Fangirling. Over Chuck's Supernatural books. Now Wincest might be a bit too much to deal with, but Destiel he might be able to get on board with... Especially after being around the two people involved for three days straight.

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one state into another. And what is grace, if not energy?

SLASH. It all started with Dean's perfectly healthy hatred of frivilous holidays and a much-coveted sack of dust. Poor Castiel doesn't fully understand 'romance' to begin with, and this crash course is most unwelcome.

Castiel consults a Cosmo article in order to seduce Dean.

Preslash. Dean discovers that Castiel is actually 'his' angel...he just doesn't realize just how possessive that realization has made him.

A strange boy shows up at Dean and Sam’s motel room. Maybe he needs help, or maybe he’s there to help them—they can’t quite tell. Spoilers through 4.10. Not an OC.
