Shadowhunters

Jace escapes Valentine, but the Clave treats him as a traitor. Valentine steals the Soul-Sword, and Clary learns to create new runes. Jocelyn's death at the hands of a possessed Alec changes everything for Clary. In the back half, Jace learns he's a Herondale and not her brother. Newcomer Sebastian turns out to be Jonathan, Valentine's real son. Magnus and Alec split. At Lake Lyn, the true Mortal Mirror, Clary kills Valentine. Jace dies in the battle and comes back through the wish Clary asks of the angel Raziel. Jonathan dies, Magnus and Alec reunite, and a woman made of demons calls Jonathan her son.
