Tonight's episode # Thinman brings back the Ghostfacers. It is their first appearance since It's a Terrible Life in season four.

Here's what we know.

THE GHOSTFACERS RETURN — A teenage girl (guest star Ali Webb) is killed and the final selfie she took before the attack shows a ghostly figure in the background.  Looking for something to keep them busy, Dean (Jensen Ackles) and Sam (Jared Padalecki) head to Washington to find the ghost.  While the two interview the girl’s mother, Betty (guest star Maria Marlow), they are surprised when she starts talking about cold spots and fritzing.  When they ask her about bringing up paranormal signs, Betty replies that the “supernaturalists” who called earlier brought it up.  Enter Harry (Travis Wester) and Ed (guest star A.J. Buckley), the famous supernaturalists.  Jeannot Szwarc directed the episode written by Jenny Klein (916).

This episode was filmed out of order, although I don't know if that was because they were working around schedules or if this just got switched for other reasons. In any case this sounds as it it could be another standalone episode. Historically the Ghostfacers have been somewhat light hearted although those episodes can be dark as well. This season even the episodes that look as though they will be lighter have still led to some controversial conversations between Sam and Dean. An interview with Travis Wester and A.J. Buckley mentions that there is often tragedy in their episodes so that may be an indication that this will have darker overtones.

We only have a few hours before we find out.
