Introduced to Sam (Jared Padalecki) and Dean (Jensen Ackles) courtesy of season 7's Dick Roman (James Patrick Stuart), Charlie (Felicia Day) is currently off in Oz with Dorothy (Tiio Horn). Charlie has not been seen since season 9's "Slumber Party," but the Supernatural writers are not opposed to bringing her back - whether it be in Oz or in the world of the Winchesters.

"I'd love to see more of Charlie anywhere!" tweeted "Slumber Party" writer Robbie Thompson on Tuesday.

While Charlie may be a genius when it comes to coding and hacking, Charlie is still learning when it comes to ganking the creatures that go bump in the night. Luckily for viewers, Charlie's progression towards becoming a full-fledged hunter has played out in front of their eyes - and Thompson believes it is only just beginning.

"I think her role is evolving," Thompson tweeted. "Started as a neophyte, then grew and is now on her own adventure."
