Cat and Bones have to finally defeat Apollyon who is trying to start a war between ghouls and vampires using Cat's half-breed heritage as the trigger. Cat is also trying to adjust to being a "freaky vampire' in that she feeds on other vampires rather than humans. She also absorbs the power of those she feeds from making her very cautious in her choice of dinner. She adds another power when she sees Marie Laveau to try to see which side of the war she will be on. Great episode! I laughed and cried -- sometimes on the same page.
