It all started with a trip. Sherlock had been acting weird, and everyone thought he was just stressed, so he and John go on a trip to Fiji. Yet, what was supposed to be a relaxing vacation from the stresses of detective work only opened the door for much more stress and confusion when John begins to have strange feelings around his colleague, Sherlock Holmes. And Sherlock is still acting strange.

John is possessed. Castiel is injured. Doctor, please help.
