Dean is rushing to save Lisa and Ben in the first hour of the two-hour finale, while Sam will have the wall in his head come tumbling down in the second hour.
The battle for heaven comes to a head in the two-hour finale of "Supernatural" season 6. In the first hour, a demon kidnaps Ben (guest star Nicholas Elia) and Lisa (guest star Cindy Sampson) to get to Dean. The eldest Winchester brother and Sam are forced to join an unlikely ally to free them.
The second hour, dedicated primarily to Sam, will have the wall in his head come tumbling down. All hell breaks loose, but Dean and Bobby are, for once, at a total loss on how to help him and are forced to stand by and do nothing while Sam breaks.
Words are, there are some deaths in the season finale. Also in the episodes, Lanette Ware appears as Raphael, Mark A. Sheppard returns as Crowley and Kim Johnston Ulrich returns as Dr. Visyak.
"Let It Bleed" and "The Man Who Knew Too Much" will air Friday, May 20 starting at 8:00 P.M. on The CW. The show has been renewed for a seventh season.
