Yesterday

"Yesterday" is the eleventh episode of the first season of Psychopathy. It is the season finale.

Overview

 * CJ cannot influence Reenah while she's in the presence of both Dr. Farmer and Tamina, and Reenah confesses what she's been seeing and what she's been doing; being convinced by her dead husband to murder.
 * Fearing for her job and her life, Dr. Farmer tries to leave the room to call the police, but Reenah begs her to stay, saying that being in the room is keeping her sane. She reluctantly agrees and dials the number for the police.
 * Tamina realizes that Reenah killed Calvin. Tamina bursts into tears, smacks Reenah across the face, and runs out despite Reenah's begging her to stay.
 * At that moment, CJ regains his voice and convinces Reenah to finish out her plan.
 * It's a race against the clock for Reenah to finish the job before Dr. Farmer can get the police to her.
 * Reenah arrives at the restaurant she had chosen but, the moment she steps inside, the sprinklers turn on and ruin her plan.
 * The patrons quickly make to leave the restaurant. In a crazed desperation, Reenah blocks the door and forces everyone to stay inside while she tries to hatch a new plan.
 * The police storm the door and easily capture Reenah.
 * In her mind, Reenah sees each person in her life truly rejecting her: Dr. Farmer terrified of her, her mother hating her, her brother saddened, and CJ mocking her and berating her as a failure and a psychopath.
