Supernatural returns after 3 weeks of hiatus. The preview shows Dean playing a "pacman like game" with Charlie (Felicia Day) where if they die in the game dream they will die in real life. There goal in this arcade of nightmare is to save and protect a patient who happened to be Sam.
Concerned about the physical toll the second trial took on Sam (Jared Padalecki), Dean (Jensen Ackles) benches his brother from hunting until he heals up.
So, when geektastic hacker Charlie (guest star Felicia Day) stumbles upon a case and finds the boys, Dean decides it’s time to teach Charlie how to be a hunter-in-training.
While happy to see “her highness,” the boys suspect Charlie is hiding something, a secret that could get her killed.
