Supernatural's Winchester brothers have picked up a new case, but they will soon run into a pair of familiar - and unwanted - faces.

What's Crowley's Dangerous New 'Supernatural' Addiction? Will He Compromise The Winchesters' Mission In 'Blade Runner'?

The Ghostfacers are making a comeback in "#Thinman," but the Winchesters really wish they would just please, please go away. Well, Dean (Jensen Ackles) isn't so keen on the word 'please' - he would rather just shoot them in the kneecaps (see video below).

When a teenage girl mysteriously dies inside her locked bedroom, her final selfie will hold an eerie clue to solving her death. Sam (Jared Padalecki) and Dean will head out to Washington (sans Castiel) to take on the case, but they soon learn that Harry Spangler (Travis Wester) and Ed Zeddmore (A.J. Buckley) are also in town.

Find out if the Ghostfacers can hold their own when Supernatural airs Tuesdays at 9 p.m. ET on The CW.
