The number of supernatural beings in the hit CW's series "Supernatural" seem to be endless. Season 10 has its fair share of suspense, dram, action and secrets of the supernatural world. Episode 11 named "There's No Place Like Home" will see the re-appearance of Charlie (guest star Felicia Day).

The attractive Winchester brothers scan the Internet for any suspected paranormal activity when they chance across a video that depicts Charlie beating a District Attorney. Dean (Jensen Ackles) feels Charlie is back from Oz in order to hunt demons and assumes the Attorney may have been one. They go in search for Charlie and when they do actually find her, they are shocked with the real reason of her comeback.

Teasers unveiled that Charlie would actually come back under difficult circumstances and would bring back something dangerous from Oz. The trio will have to work together and help Charlie. Speculations circulating on the Internet are guessing that Charlie may have turned dark after her stint at Oz, but some say she is just there to help. Her true nature will only be seen once the episode airs on CW. Charlie and Dean are also touted to have a fight, as seen in the episode's promotional video.

While fans are raring for the episode 11, episode 12 also has a lot in store for fans. Titled "About A Boy", it will bring a new case to the brothers as people are seen disappearing with only their clothes left behind. Looks like Supernatural promises to be a suspense-packed series this season. Additionally, teasers reveal that Dean will turn into a 14-year-old boy in episode 12, which will be quiet interesting to see.

Episode 11 will air on the small screen on Tuesday, Jan. 27, 2015 at 9 p.m. Eastern time on CW while episode 12 will air on Feb. 3, 2015.
