Lucifer realizes that he needs a stage and a crowd to fulfill his mission in Episode 7 of "Supernatural" Season 12. Meanwhile, Mary may bid farewell to Dean and Sam soon.

Latest "Supernatural" Season 12 episode 7 spoilers reveal that Lucifer plans on rocking the stage. He disguises as the rock star Vince Vincente to lure the crowd and to kill them all. According to Comic Book Movie, the Winchesters boys, Castiel and Crowley must stop the rock star from performing.

As per synopsis of episode 7 "Rock Never Dies," "Lucifer (Rick Springfield) realizes that as rock star Vince Vicente, he can get his fans to do whatever he wants. Thrilled with this power, Lucifer arranges to play a secret VIP concert in order to kill all of them. Sam (Jared Padalecki), Dean (Jensen Ackles) and Castiel (Misha Collins) enter the underbelly of the music industry to try to stop him."

CarterMatt notes that episode 7 of "Supernatural" Season 12 might be usual dramatic. And fun, in general, seeing the hunters track down the evil-possessed rock star. With the musically inclined episode, CW is definitely bringing a new kind of crazy scene to the table.

Meanwhile, TVLine fears that Mary will soon say goodbye to her sons. According to the site, Mary doesn't feel that she belongs on Earth. And it was never her intention to go down from heaven as Dean used his gift from The Darkness to resurrect her from the dead.

It is also unknown if Dean did offer Mary to Billie the Reaper in order to save Sam, Jody and the rest of the hunters last episode in "Supernatural" Season 12. While this sounds way harsh, it certainly seems that way. And it's something that the series can do. If so, the Winchester family issues runs deeper than we thought. If not, Mary will probably stay with her sons until she dies on the job.

Stay tuned for more "Supernatural" Season 12 news and spoilers.
