“There Will Be Blood.” Sounds kind of ominous, huh? Not for “Supernatural,” especially if you watched last week’s episode in which Sam and Dean discovered they need to collect the blood of the three fallens in order to kill the Leviathan. As usual, it’s not going to be a walk in the park.

According to Executive Producer Robert Singer, the adventure this week is going to be complicated by one very unstable Ghost!Bobby:

“Bobby as a ghost is beginning to become more and more unstable. The boys not only see him as a threat to himself but a threat to their plan to deal with the Leviathans. Secure a weapon, they’re ready to go in, and the fly in the ointment turns out to be Bobby and how to deal with him becomes both a tactical and emotional problem.”

No matter what Bobby’s intent, he’s determined to help, as shown in the below promo clip.  He gives his take on what needs to be done to Dean, even if the fogging of the mirror creeps Dean out. This second to last episode of the season is directed by fan favorite Guy Norman Bee, so we already know it’s going to be something extraordinary!

Here’s the official CW synopsis for “There Will Be Blood”:

SAM AND DEAN SEEK OUT AN ALPHA — In order to defeat Dick Roman (guest star James Patrick Stuart) and the Leviathans, Sam and Dean must locate three key items. Castiel helps with one but for the last objects, the Winchesters must face two of their strongest opponents – an Alpha (guest star Rick Worthy) and Crowley (guest star Mark Sheppard). Meanwhile, Bobby (guest star Jim Beaver) tries out a new ghost trick that ends up being very dangerous. Guy Bee directed the episode written by Andrew Dabb & Daniel Loflin.
