From 2006 to 2007, Vincent adopts the disguise of the "Blackmailer" to rape, murder, and blackmail several of the show's characters. Alistair (who was presumed dead at the time), had manipulated Vincent into performing these criminal actions. Vincent's first act as the "Blackmailer" is to repeatedly rape his paternal half-sister Fancy Crane; he frames Fancy's boyfriend Luis Lopez-Fitzgerald for the rapes by planting his semen inside her. After his maternal half-sister Simone Russell's girlfriend Rae Thomas learns the truth, he murders her and frames Luis for the crime. As the storyline progresses, Vincent begins to harbor an obsession with Theresa's love interest Ethan Winthrop and blackmails Judge JE Reilly into sentencing Luis to death by lethal injection. Vincent's aunt Sheridan Crane was the only person to identify him, but she keeps his secret on the sole condition that he brings her niece Pretty Crane back to Harmony to destroy Fancy's relationship with Luis. Vincent convinces Sheridan to kill Theresa with an electric chair, but she is interrupted by Theresa's rival Gwen Hotchkiss.
