Professor Bruttenholm had provided BPRD Agent Simon Anders clues about where to start his hunt for vampires who worshiped Hecate. Now, the Professor must investigate, when news reaches him of the widespread carnage at one of those sites. Varvara taunts the Professor, asking how long did he think that he could keep his monsters in check (a reference to Bruttenholm's ward, Hellboy).
The Professor, with military attachment, tracks Anders to a mansion. Bruttenholm enters alone to confront him, and is shocked at what he sees. Anders, from having the souls of two vampires trapped within his own, has grown a connection with dark forces, and acquired both incredible power and a blood lust.
The Professor attempts reasoning with Anders, as it is clear he cannot stop him physically. Anders shrugs Bruttenholm aside, sparing his life in light of his debts to the Professor. Anders continues his hunt for vampires, who flee in anticipation; Bruttenholm returns to B.P.R.D. headquarters to consider his next move.
