S8, E11: FELICIA DAY returns! Sam and Dean investigate the mysterious deaths of two LARPers (Live Action Role Players) who were engaged in a game entitled Moondoor. The guys are thrilled to discover the Queen of Moondoor is none other than Charlie Bradbury (guest star FELICIA DAY), their quirky hacker friend who helped them fight Dick Roman last season. The three learn that an actual fairy (guest star TIFFANY DUPONT) has been enslaved and commandeered to harm people – and the only way to stop her is to find her master, an overzealous participant in the game.
