Aidan is worried that he killed werewolf Josh, while Sally is trapped in what looks like a spa facility with Donna.
Syfy has provided fans with the first look at "Being Human" season 4 through a promo video. It opens with Sally enjoying a relaxing treatment in what seems to be a spa facility before she realizes that something's wrong as her hand gets covered with blood. She then confronts Donna for keeping them in the place.
Josh is trapped in his wolf body and Aidan and Nora are trying to help him, but that may not end well. After running away from a wolf in the woods, Aidan is seen stabbing someone or something and then anxiously saying, "Please tell me I didn't just kill my best friend."
Season 4 of "Being Human" opens with the roommates coping with Josh, who is permanently a wolf, although the full moon has a very different effect on him now, which drives Nora to extremes in order to get her husband back.
Visitors from Aidan's haunted past, including an elusive character bearing an uncanny likeness to his long lost wife Suzanna (Katharine Isabelle), as well as his maker Bishop (Mark Pellegrino), collide with the present and Aidan is forced to make impossible decisions affecting those closest to him.
As for Sally, she finds herself trapped alone with the witch, Donna (Amy Aquino), but her newfound magical powers may be more than either of them bargained for.
The new installment will premiere January 2014 on Syfy.
