Supernatural's Winchester brothers are in for some good old-fashioned hunting during "The Purge."

Sam (Jared Padalecki) and Dean (Jensen Ackles) have been hit with the angelic and the demonic from all angels during season 8, and the hunters are going back to basics as they work to repair their fractured relationship. While they took on werewolves reunited with Garth (DJ Qualls) last week, this Tuesday's episode will be just the brothers on the trail of a fat-sucking monster.

"The show works best when it's the brothers facing some conflict together. It's not just facing a monster. If it was just how do we kill this monster of the week, the show would not be on the air, to be perfectly frank," said executive producer Jeremy Carver in regards to the importance of the brother's relationship, according to E!. "It's a show that has infused this brotherly relationship and extending it to the supporting characters, so it's this familial structure that keeps people coming back."

During "Sharp Teeth," Sam told Dean in no uncertain terms that they were no longer brothers, so it seems prudent for the writers to take an episode to separate the boys from everything else in order to put them back on track and make them trust each other again.
