'Supernatural' Season 12 Spoilers: Dean Loses Memories; Mary Double Crossed By Men of Letters?

What will happen to Dean if he loses his memory of the people he loves? This will be the main problem that the Winchesters have to face in "Supernatural" Season 12 Episode 11 entitled "Regarding Dean."

According to a synopsis posted by SpoilerTV, the elder Winchester brother will fall victim to a spell that will rapidly erase his memory. In order to save his brother, Sam will have to get Rowena's help to go to an old world to find the counterspell that would bring his brother back to the way he was.

It is expected that in the episode, Dean will revert to a childlike state but what would appear cute and funny at first would prove to be alarming once his memories of the people he loves start to fade, and along with it the very core of what makes Dean himself.

The site also posted a synopsis of Episode 12 entitled "Stuck in the Middle (with You)." In the episode, Mary asks for the help of Sam, Dean and Castiel for a case she's working on but hides the fact that it has something to do with the British Men of Letters. Trouble is expected to erupt when she is betrayed along the way.

"Supernatural" Episode 11 will air on February 9 while Episode 12 will air a week after on February 16 on The CW.

Meanwhile, actors Jared Padalecki and Jensen Ackles, who play Sam and Dean Winchester in the show confirmed that Billie's death will have consequences for Team Free Will, reported BuddyTV.

"Dean killed Death and nothing really happened. So they're a little gun-shy...I'm sure [consequences are] coming," he said.   

Ackles said that the brothers got away with killing Death relatively unscathed but the death of the Reaper Billie, who took on the reins that their old boss left behind, would definitely have some backlash.
