Next Tuesday will see Felicia Day returning to 'Supernatural' once more as her ever-popular pop culture junkie hacker Charlie Bradbury, throwing a "Slumber Party" with Sam and Dean that takes the trio to 'The Wizard of Oz,' of all things. We've seen the photos, but check out Day's return in the first clip from next week's all-new 'Supernatural' installment "Slumber Party!"

Working with the boys from the Men of Letters base once more, the latest clip from "Slumber Party" sees Charlie referencing some classic 'Supernatural' series history, namely that the entire collected Winchester works are available for purchase, courtesy of Carver Edlund. Makes you wonder, will we ever revisit Chuck's role in the grand scheme of things?

From The CW’s official press description of “Slumber Party”:


Sam (Jared Padalecki) and Dean (Jensen Ackles) discover that the table in the Men of Letters house (the one that lit up like a Christmas Tree when the angels fell), has an ancient computer attached to it. They figure if they can get the computer on, they can track the angels. Who better to call for help than the best IT girl there is, Charlie (guest star Felicia Day)?

While moving the massive computer, they dislodge a hidden hexbag that unleashes a magical green-webbed wall. Sam and Dean break through it and discover the one and only Dorothy (guest star Tiio Horn) from Oz. She had trapped herself and the wicked witch (guest star Maya Massar) in the web years ago to stop the witch from finding the key that would open the gate that connected their world with Oz. With the wall broken, a massive and magical fight ensues that threatens to destroy the Men of Letters house.

Will Charlie drop a house on the wicked witch? Will her association with the Winchesters finally get the better of her? You can check out the sneak peek of Felicia Day's return from “Slumber Party” above, and give us your predictions for ‘Supernatural”s trip to the magical land of Oz in the comments!
