"The Walking Dead" actor Jeffrey Dean Morgan will be guest starring in the next episode of "Supernatural" Season 12. That said, The CW has finally released the official plot summary and preview clip of episode 8 'Lotus'. Plus, a quick recap of episode 7 'Rock Never Dies' is highlighted here for fans who have missed to watch it.

"The Walking Dead" actor Jeffrey Dean Morgan has officially landed a role in "Supernatural" Season 12. According to International Business Times, the 50-year-old American actor will play the guest role of John Eric Winchester, Sam and Dean's father.

Executive producer Andrew Dabb even assured fans that Morgan can balance both his role here and in TWD as Negan.

Morgan reappears in the 8th episode of the Eric Kripke-created series.

As for the official plot synopsis of episode 8, Spoilers Guide notes, "Lucifer's (Mark Pellegrino) search for power and influence in a vessel lands him in the White House. The President of The United States (guest star David Chisum) unknowingly makes a deal with the devil, leading Sam Winchester (Jared Padalecki), Dean (Jensen Ackles), Angel Castiel (Misha Collins), Crowley (Mark A. Sheppard) and Rowena (guest star Ruth Connell) to band together to fight the Dark Lord."

For a quick rundown of last week's episode 7 "Rock Never Dies", Entertainment Weekly reports Lucifer learned that he can do whatever he wanted as a rock star Vince Vincente. Because of that, he arranged a concert to kill all of the audience.

To the rescue, Sam, Dean, and Angel Castiel came to stop his evil plan.

"Supernatural" Season 12 episode 8 is titled as "Lotus". The upcoming episode is scheduled to premiere on Thursday, December 8, 2016, at 9:00 p.m. EST first and exclusive on The CW.
