A ghost from “Supernatural” past will be making her Season 10 debut when episode 11 airs on Tuesday, Jan. 27. Do you have any guesses of who might be making their reprisal in next week’s installment? Well, one major clue to help you figure out the answer is hidden within the episode title, “There’s No Place Like Home.”

That’s right! Charlie Bradburry, portrayed by Felicia Day, will be returning to the hit CW series next week on “Supernatural.” The last time fans saw Charlie was in Season 9 when the “Hobbit” loving, adventure-seeking character wandered into the unknown land of Oz, hand-in-hand with Dorothy (Tiio Horn) herself!

“You have no idea what’s in Oz. There could be flying monkeys, armies of witches -- there’s all kinds of danger,” Dean (Jensen Ackles) warned Charlie before she entered the supernatural world.

“Promise?” she responded, enticed by the thrill.

But according to the synopsis of episode 11, it looks like Dean may have been right to be fearful of Oz.

“Sam (Jared Padalecki) is scanning the Internet for suspicious paranormal activity and comes across a video of Charlie (guest star Felicia Day) beating up a district attorney,” the summary for “There’s No Place Like Home” teases. 

Dean will suspect that their old friend is back from Oz and hunting on her own, “assuming the district attorney must have been a demon.” However, when the Winchester brothers do reunite with Charlie, they’ll be “shocked when she tells them why she really came back” from the Land of Oz.

When TVLine first reported that Day would reprise her role of Charlie in 2012, it was teased that the character would return from Oz “under precarious circumstances” and that she would be bringing back something “very dangerous” to the real world with her.
