was, and responds, "It's why I had you", so Cassandra agrees to fight her to the death once more. After a closely matched battle, Cassandra manages to break Shiva's neck, paralyzing her. She appears ready to place Shiva in the Lazarus Pit, but Shiva pleads with her not to do so. Instead, Cassandra impales Shiva on a hook hanging over the pit, apparently killing her.
