Plot
While under possession by Sebastian, Jace goes missing. Clary and the Shadowhunter institute communicate with the Seelie Queen who agrees to help them in exchange for faerie rings that allow telepathic connections. While looking for them, Clary finds Jace communicating with Sebastian. In the morning, Clary wakes up to find Jace in bed with her and is horrified. Jocelyn and Luke wake up to find Sebastian in the house. Jace and Sebastian try to get Clary to join them but she refuses.

Clary decides to join them as a spy using the Faerie rings to communicate with Simon. Clary finds out Jace and Sebastian are connected with a mark that keeps healing and if one is killed the other will die. Izzy and Jocelyn talk to the Iron Sisters who say that only a blade of heaven can undo the possession and connection. While with Jace and Sebastian Clary discovers the the rune controlling Jace is fading, while free from possession he reveals Sebastian's plan. Jace plans to turn himself into the Clave to avoid any issues but Clary gets Sebastian's attention so he heals the rune to take control over Jace.

Simon makes a deal with the Angel Raziel, His Mark of Cane for the Blade of Heaven. Simon tells Clary to meet him at the Seventh Sacred Site, but to keep Sebastian from overhearing them she smashes the ring. At the Seventh Sacred Site, Clary turns on Sebastian and they fight. Sebastian defeats Clary and tries to rape her. Clary manages to get away and hides while Sebastian attempts a magic ritual using Lilith's blood to create Dark Shadowhunters with the Infernal Cup. Sebastian had kidnapped Amatis Greymark who they test the cup on turning her into an Endarkened Shadowhunter.

During a fight with the Shadowhunters against the Endarkened and Sebastian, Clary uses the Blade of Heaven to free Jace from his possession by stabbing him with the sword enlightening him with heavenly fire but sending the sword back to heaven. Sebastian flees promising revenge against the shadowhunters and that his Endarkned will change the world. Jace slowly heals from his injuries and is free from possession. Meanwhile Alec's mother Maryse shows the Silent brothers a pair of angel wings given to he by Sebastian signed with his birth name claiming that he's coming.

In a mid-credits scene, Maureen Brown hunts down the vampire leader Camille Belcourt and kills her. She then takes over the New York vampire clan and meets with Alec boasting about the death of Camille.
