|Episode(s)||8.11 LARP and the Real Girl|
Gilda is a fairy from the Hollow Forest of Arkhmoor. She is brought to Earth and put under a spell by Gerry, who forces her to injure and later kill those who stand in his way of becoming king of Moondoor – a LARPing game. She uses magic to injure and kill the victims in the style of medieval punishments – hobbling, drawing and quartering and the plague. Gilda can only be released if a hero destroys the spellbook, breaking the spell.
Under Gerry's orders, she captures Charlie so he can "rescue" her and become a hero. While Gilda holds Charlie prisoner, Charlie becomes attracted to Gilda and kisses her. Sam, Dean and Gerry arrive and Gerry forces Gilda to use a suit of armor to pin down Sam while he tries to kill Dean with a sword he has Gilda transform to real. In the fight that follows, Dean knocks Gerry's spellbook from him and Charlie stabs it with a knife, destroying it and breaking the spell. Dean knocks out Gerry.
