Supernatural's new sanctum has a slight ghost infestation, but the Winchesters' paranormal problem may work to their advantage.

Ghostfacers' 'Supernatural' Mission Revealed; The Winchesters Take On Selfies In '#Thinman'

A haunting in the Men of Letters bunker will come as a major surprise to Sam (Jared Padalecki) and Dean (Jensen Ackles), but their investigation into the bunker's ghostly inhabitant will lead them to something the demons have been keeping secret.

The brothers will have a little trouble getting what they want, however. A man named Del will get the better of at least one Winchester, but the potential demon won't have the upper hand long (see gallery above).

Castiel's Angelic Dilemma Heats Up On 'Supernatural'

Unfortunately for Castiel (Misha Collins), it doesn't look like there will be anyone to bail him out when he gets picked up by Bartholomew (Adam Harrington) and his followers. The angel war is picking up steam, and Cas will have to find his role in the new order.

"Now that he's an angel again, he's going to have to find his place in this angelic battle, and it may not be the place he imagined for himself, which is going to confront him with some choices he perhaps never thought he'd have to make," said executive producer Jeremy Carver, according to Entertainment Weekly. "So he's right back in the fire, as it were."

While the "Captives" promo includes Snookie, the Jersey Shore star is not included in the episode summary or the promo photos. Nicole Polizzi visited the Supernatural mid-January, which corresponds to filming dates for episode 16, "Blade Runners." If the reality personality doesn't appear in "Captives," viewers can look for her on March 18.

Supernatural airs Tuesdays at 9 p.m. ET on the CW. Click the video below to see a preview for the Feb. 25 episode, "Captives."
