Following Simon's accident that confined him to a wheelchair, Purnell was hired as Simon's counselor to keep track of his mental progress due to the trauma he endured. Purnell notes that Simon is loath to speak of his personal life, refusing to comment on topics regarding his home or school life. Due to a lack of success in their sessions, he recommends Simon try a form of cognitive therapy by writing a book to express his thoughts and emotions, to get them out of his head.
This suggestion leads to the events of the game, a depiction of Simon's mental struggle against his inner demons. A twisted, deranged, and sinister version of Purnell in a gasmask is seen in this world, dropping false hints to Simon about a possible biological outbreak - the Doctor expressing belief that Simon isn't even real, and that everyone else around him is psychotic despite the fact he murders two individuals in cold blood.Simon comes to believe that the Doctor is responsible for all of this and chases him to a mental asylum located deep in the forest, the Doctor eventually making contact with Simon and offering to open a gate for him in exchange for Simon handing over a pistol located in the asylum's bowling alley.
The player's choice decides what ending is unlocked - if the player gives Purnell the gun, he thanks Simon for his trust and gives him the key to the gate before loading the pistol and shooting him in the shoulder. If Simon refuses to give him the gun he expresses disappointment in Simon before tossing him the key anyways, shortly after still shooting him with his snub-nose revolver.
After the encounter by the gate, Simon pursues Purnell up to the attic of the asylum and engages him in a gunfight. The battle eventually ends in Simon's victory, the Doctor laying wounded on the ground before Simon approaches him and finishes him off by stomping on his face multiple times, crushing his skull in and destroying his mask.
Following the conclusion of the game, the ending unlocked decides the fate of the real Doctor Purnell. If Simon chose to not trust him with the gun, either Ending 1 or Ending 3 is unlocked - in which Simon murders Purnell in his apartment, regarding his attempts at helping him either to be done out of spite or simply to be useless, respectfully. But if Simon trusts him with the gun, Ending 2 or Ending 4 are unlocked.
In Ending 2 Simon commits suicide following his murder of Sophie and he openly states his apologies to Purnell in the final notes of his book, stating that not everyone can be saved. In Ending 4 Simon does not kill himself and is instead convicted to a mental hospital following a psychotic break that causes him to accidentally shoot two police officers. Purnell then becomes Simon's official mentor in the asylum, working to bring Simon back to mental health (something that Simon is grateful for).
Completing the game with any ending will unlock "Doctor Mode". You play as Doctor Purnell, armed with the Taurus Revolver and equipped with a nightvision built-in gasmask. He will have to battle through armies of monsters created by Simon's mind in order to get into the apartment which Simon lives in, to destroy the book Simon has written.
