Charlie is easily one of the show's best side characters, and the funny, emotional, and frightening "Pac-Man Fever" illustrates why she was such a great addition to the show. The episode begins with Charlie enlisting help from the guys when a suspected Djinn appears to be killing people in Kansas, but it quickly evolves into a jaunt through Charlie's recurring, video game-themed nightmare. Not only does this outing include excellent bonding moments between Dean and Charlie, it also ends with one of the show's most moving moments as Charlie says goodbye to her mother.
