Vicki tries to get some information from her former partner and competitor, Detective - Sergeant Mike Cellucci, which leads to their arguments over her involvement.
Her RP makes her useless at night and Henry sleeps during the day, so they agree to share the investigation.
Vicki finds Henry almost dead in his apartment and the grimoire stolen and she realises that he needs to be fed to stay alive and heal, so she allows him to drink from her wrist.
While the investigation continues, Vicki discovers that a college student named Norman Birdwell, who is a new friend of Coreen's, summoned the demon.
He kidnaps the two of them, willing to sacrifice Vicki's blood to call a new, more powerful demon, Astaroth, who wants to bring about a Hell on Earth.
Together, the three defeat him, and Mike Cellucci, who has been looking for Vicki, arrives in time to see Henry's vampire powers and the demon he fights with.
