Shadow Hunters Season 01 Episode 09

Following the Forsaken attack, the Institute is on high alert. Lydia arrests Meliorn for supposedly leaking Shadowhunter information to Valentine. During his interrogation, Meliorn let's slip that Clary is in possession of the Mortal Cup. Jace, Isabelle, and Clary decide to take matters into their own hands to prevent the Cup from reaching the Clave. With the help of Magnus, the three Shadowhunters sneak the Cup out of the Institute. Later, Isabelle, Clary, Jace, Simon, Luke and Raphael team up to rescue Meliorn from his impending torture in the City of Bones. Afterward, Meliorn informs Clary that he can help find her father. Alec's siding with Lydia and the Clave causes rifts with his personal relationships, and Simon makes peace with his newfound status as a vampire.
