Sam and Dean Winchester (Jared Padalecki and Jensen Ackles) will be having computer troubles in "Supernatural" Season 9, Episode 4 "Slumber Party" and they turn to one person for help: computer hacker Charlie Bradbury. Felicia Day returns as the favorite red-haired computer expert and the actress gave fans a preview on her character's involvement in the TV series' take on the "Wizard of Oz" tale.

In the Zap2it report, Felicia Day revealed that the Winchester brothers call on Charlie to help them with a computer they found in the "Men of Letters" bunker. Ms Day explained: "The bunker is relatively new to the guys and it's such an amazing place. There's a number of rooms and you could find pretty much anything there. They find this computer that they don't really know how to crack or operate so they call on Charlie since she's obviously really good at this stuff. That's the essence of it and through that exploration they uncover Dorothy and the Wizard of Oz."

However, the gang will be dealing with a series of disasters after the revelation that "Dorothy and the Wicked Witch have been sort of entrapped in the "Men of Letters" bunker." Will the "Supernatural" fans be seeing more of Charlie in Season 9 after her return in Episode 4?

"This is a little bit more standalone, yes, but the cool part is, at the very end of this episode, Charlie is faced with a huge decision and it's very interesting to see how people react to that and how she reacts to it as well," Ms Day stated in the Access Hollywood report.

The CW network has officially released as well the synopsis for the upcoming Episode 5 titled "Dog Dean Afternoon" and the episode appears to be a really amusing one. The synopsis reads: "DOGGIE DEANLITTLE - While investigating two bizarre murders, Sam (Jared Padalecki) and Dean (Jensen Ackles) realize there is an eyewitness to both gruesome deaths - a German Sheppard. Anxious to find out if they are dealing with a witch, a skinwalker or other supernatural monster, the guys look up a spell that could let Dean "communicate" with the dog. Unfortunately, the spell comes with side effects that no one saw coming."

"Supernatural" Season 9 airs Tuesday nights at 9/8c on the CW network with Episode 5 "Dog Dean Afternoon" scheduled on November 5.
