And then there’’s the fact that the whole Alex-and-Seth combination is pretty dangerous: if Seth drains Alex of her power, he’’ll become the God Killer and the most powerful being on the planet. The one person needed to stop the impending destruction has been dead for centuries - and Alex will have to search for him in the Underworld.
