History Recap / PsychS05E016Yang3In2D

A college student named Allison Cowley is in the police station, in tears after being kidnapped by the infamous SerialKiller known as Mr. Yin. Nobody has seen Yin since last year, but there have been plenty of nuts and false leads… but Cowley provides them with something she grabbed on the way out: a disturbing photograph of Yang smiling for the camera with Shawn as a child. The police storm the house where she was held captive, but it seems to be an ordinary place – though Allison knows enough about the house itself that Shawn is convinced of her honesty. Shawn puts her up at Henry’s house for her own safety, but she’s soon kidnapped again, from straight out of Shawn’s old bedroom. With the clock ticking, and Mary Lightly dead, Shawn and Gus get Mr. Yang out of the psychiatric prison to help find the notorious Mr. Yin, and take him down once and for all…

* ApocalypticLog: Mary Lightly left a videotape of his musings and poetry regarding the case before he was killed. Yin stole it, but left a box for the police to find. It’s mostly rambling, but near the end – only two days before he was killed – he leaves two important bits of information: Yin seems to be building up to a major finale to his career, and the more he looks into Yang, the more convinced he’s become that she’s just as much a victim of Yin as anyone.

* PutOnABus: After the last three season finales, Allison is set up perfectly to be another season finale boss in the same vein, but the show finished its eight seasons without her coming back. [[spoiler:It comes back in [[Recap/PsychTheMovie Psych: The Movie.]]]]

* BitchInSheepsClothing: [[spoiler: Allison Cowley turns out to be Yin’s newest apprentice after Yang was jailed. She pretended to be another one of Yin’s victims in order to lure Shawn and Gus into a trap.]]

* DesignatedGirlFight: [[spoiler: Juliet is ambushed by Allison, they beat the hell out of each other, and Allison is eventually arrested.]]

* DyingDeclarationOfHate: [[spoiler: As Yin lies dying, he tells Yang he never loved her. Yang knows.]]

* EvilMentor: Yin turns out to be this; Yang was his apprentice and daughter, and he was very interested in manipulating her to be as much of a serial killer as him. When she became obsessed with Shawn and his seemingly-perfect childhood, he used that against her, too. He was outraged at her capture, not only because of her failure, but because he was envious of the resulting fame that her book brought her. [[spoiler: Later, he became the mentor to Allison.]]
* EvilTeacher: an unusual variant. Yin is a well-known professor at a local university, and is also an EvilMentor to Yang [[spoiler: and later, to Allison Cowley]], but nobody else at the university had any hint of the depths of his depravity.

* GuestStar: [[spoiler:Creator/PeterWeller is Mr. Yin.]]
* HistoryRepeats: [[spoiler: As Allison is driven away in a squad car near the end, she gives Shawn a crazy-eyed look as it drives off, an eerie CallBack to a similar scene near the end of “An Evening With Mr. Yang” with Yang in the back of the car that time. The only difference is Allison’s DeathGlare compared to Yang’s SlasherSmile.]]

* INeverSaidItWasPoison: [[spoiler: Juliet figures out Allison is up to something when she mentions she’d just awakened after Yin kidnapped her, but she already knows Shawn and Gus are inside the house.]]

* NotSoStoic: [[spoiler: PlayedForLaughs. At the very end, Lassiter seems to be the only member of the main cast who was directly involved with the case who wasn’t traumatized in some way by Yin’s actions. However, when he discovers Shawn and Juliet are dating, he’s practically rendered catatonic.]]

* {{Patricide}}: [[spoiler: Yang, recognizing that her father Yin will never change, puts a poisonous syringe meant for Gus into his chest.]]

* PutOnABus: After the last three season finales, Allison is set up perfectly to be another season finale boss in the same vein, but the show finished its eight seasons without her coming back.
* {{Retirony}}: [[spoiler:For Yin. He'd intended this job to be his grand finale. He burns his identity as a highly respected professor and intended to kill Shawn and Gus rather horrifically, then disappear.]]

* VillainBall: [[spoiler: After luring Shawn and Gus into a trap and legitimately having them at his mercy, Yin grabs it near the end when he decides to lecture them with some EvilGloating – after they beg him to do it. Yin even realizes they’re just stalling for time, but decides to go through with it anyway, since it’s the only way he can really satisfy himself. [[CaughtMonologuing This gives Yang enough time to get to them.]]]]
* VillainousLegacy: Yin’s troubles with deliberately setting one up have driven his actions over the last few years. [[WhyCouldntYouBeDifferent Yang proved a disappointment]] due to her obsession with Shawn, even deliberately allowing herself to be arrested to keep Shawn happy. [[spoiler: He’s decided to replace her with Allison Cowley.]]

** [[spoiler: "I never thought you'd show up... but he did. I guess that's why he's the master... and I'm the apprentice." - Allison]]

* AdultFear: Little Shawn meets and takes a photo with a seemingly normal, affable middle-aged woman. Said woman becomes obsessed with him to the point of stalking him for an unknown length of time, and eventually puts his mother in danger.

* SelfMadeOrphan: [[spoiler: Yang, recognizing that her father Yin will never change, puts a poisonous syringe meant for Gus into his chest.]]
