Sergeant Anthony Ceccoli was an Afghanistan war veteran with severe post-traumatic stress disorder (PTSD) which he was cured of in exchange for a five-year contract with the Dollhouse.
In S1: "Echoes", under the effects of the psychoactive drug N-7316, Victor (as Tom Voran) experiences a memory glitch: a flashback where he is a soldier trying to save a young woman in a war zone.
When Victor and Sierra put paint on one another's faces in S2: "Belonging", he flashes to Anthony's memory of another soldier asking him for orders in the middle of a war zone.
When he is released in S2: "Stop-Loss", even the blank state Sierra is able to say he's not ready yet, indicating that his PTSD lingers with Victor at least until he is restored to his original personality.
Topher first notices something more suspicious than herd behavior when, in "True Believer," he observes Victor's erection when in his doll state, which is not supposed to happen.
Topher and Dr. Claire Saunders review the surveillance footage of the showers and notice that Victor responds to Sierra's presence, not to any residual imprinting from his engagements with Miss Lonelyhearts.
"Spy in the House of Love" shows that "Miss Lonelyhearts" is actually Adelle, who has been hiring Victor secretly as "Roger," a suave Englishman.
The evidence seems stacked against him: she screams in response to his touch, she is found to have been having sex recently, and she tells the staff that Victor likes to "pretend they were married."
The detention confuses and upsets Victor because, as he tells Echo, he can't understand why Sierra screamed at him, and nobody has told him what action had gotten him into trouble.
In "Needs", Victor notes to Sierra that he is aware of what is happening to him while in the Dollhouse but is unable to do anything, in a sense being trapped in his own body and mind.
In "Briar Rose", Victor is imprinted with Laurence Dominic's personality to answer a question about a mysterious flash drive.
In "Belle Chose", Victor is imprinted with the mind of Terry Karrens, a comatose serial killer, in order to find out where his victims are.
Kiki's college girl behavior in Victor's male body leads to an altercation with some club patrons which Paul rescues "her" from.
In "The Left Hand", Topher imprints Victor with a copy of his own mind to stay in Los Angeles and assist him in recovering Echo from the D.C. Dollhouse.
In "Meet Jane Doe", Matthew Harding has Victor and Sierra are imprinted as a research & development scientists working under Topher to perfect the remote wipe technology.
In "A Love Supreme", Victor is programmed as a Jewish psychologist (nicknamed "Dr Freudenstein" to analyse the new, wholly self-aware Echo's mental state.
He is then captured by Scytheon, a Rossum Corporation-sponsored paramilitary group which recruits ex-Actives into a hive mind supersoldier unit.
Programmer Topher Brink notices when Anthony's biolink feed went offline (still in his 'adjustment' period), so Boyd investigates with the Active Echo, who is self-aware and can access multiple personality skills.
The three track a shadow creature called "Arcane" into Priya's nightmare; when they catch it, the group meet Clyde Randolph, a Rossum founder and the first victim of the Attic.
Clyde reveals the Attic is a network of brains that form a supercomputer; by killing off consciousnesses as Arcane, he reduces the "CPU count" and impairs Rossum's progress.
