'Supernatural' season 10 spoilers: Charlie helps Sam and Dean find the cure for the Mark of Cain in episode 18
A fan-favorite character returns to the tenth season of "Supernatural" in its 18th episode.
Several spoilers claim that Sam (Jared Padalecki) and Dean's (Jensen Ackles) friend Charlie (Felicia Day) will join them in a very important quest in the episode titled "Book of the Damned."
Reports claim that Charlie will call the Winchester brothers to inform them that she found the Book of the Dead that they can use to remove the Mark of Cain on Dean. However, her life was put in danger as she tried to bring the book to her friends.
The official synopsis for the episode reads:
"Charlie will call Sam and Dean to tell them she found the Book of the Dead which could help remove the Mark of Cain. The Winchesters will race to her after she tells them she's been shot by a man named Jacob Styne (guest star Jeff Branson) who says the book belongs to his family and he won't rest until he gets it back."
Meanwhile, Castiel (Misha Collins) will be joined by Metatron (Curtis Armstrong). They will go on a road trip together to look for Castiel's stolen grace. But their journey will be disrupted by several hurdles along the way.
What could possibly stop Castiel and Metatron in their quest to bring back the missing grace of Castiel?
In another note, recurring cast member Jim Beaver talked about his latest appearance in the show as Sam and Dean's beloved advisor Bobby Singer during the previous episode of "Supernatural" season 10.
The actor said that he is actually not surprised that the series creators never runs out of ideas to bring him back to the show despite dying in Season 7. And he might also be called again to appear in other episodes of the show.
"They haven't specifically said anything about anything more, but I do know that they're very fond of the character and they're always looking for a way to make use of him in a way that fits in well for the show. So I have little doubt that I'll be back as often as it's practical," the actor said during an interview with TV Line.
"Supernatural" season 10 episode 18 airs on April 6.
