Spolier Alert

Here's a look at what's coming up in the next Episode of Season Four. If you don't want to know, look elsewhere. There's plenty of yummilicious photos on this Blog :->

WHEN THE LEVEE BREAKS

Dean and Bobby have had to resort to tough love where Sam's concerned. They have locked him in Bobby's Panic Room so he can detox the Demon blood from his system. Sam is none too pleased at the fact he has been left in there ... alone. Sam starts going through the withdrawal process and even starts hallucinating that there are "other" things in the room.

Bobby is concerned that there are more and more seals being broken and tells Dean that they will need Sam to fight this battle. Dean disagrees with Bobby and turns to Castiel instead for help.

When Sam has been let out of the Panic Room, things come to a head and he and Dean have a confrontational blowout.

There is a clip below which looks very interesting indeed.
