Sirens left alive?
Why they left alive, because by all that Cade rules, they must be first targets to be brought to hell (because they plain bad, and not work on Cade anymore)
shareThe sirens has been under Case's control for centuries. They were made immortal so that they can continue working for Case. However Sybil double cross her sister Seline and trade the Salvatore brothers for her own freedom, and to stay out of hell.
