When Leslie Morgan, a sunny coffee shop owner, is murdered, Liv eats her brain and becomes positive and optimistic. Blaine comes face to face with Mr. Boss.
- The Bad Guy Wins: Leslie's daughter Cher is the villain, and convinces her boyfriend Gilbert to take the fall so she can sell the coffee shop to Stan and go to Paris with the money she made from it.
- Bait-and-Switch: Ravi recognizes a (reasonably famous) Gandhi quote. Not because he's Indian, he jokes, but because he's British, and "that manky old git cost us the crown jewel of our empire."
- Continuity Nod: Liv remembers the events of when she met Pam when she was under stalker brain effect in The Hurt Stalker
- The Cloudcuckoolander Was Right/Properly Paranoid: Pam acts like a crazy woman and is high when she met Clark and Liv, nonetheless, she is the sole coffee shop employee that believed that Leslie was murdered, and the only one that knew that Cher did it.
- "Eureka!" Moment: Mr. Boss has one when he realizes Blaine is the informant who's been working with Peyton to bring him down.
- False Flag Operation: Blaine arranged one in the backstory to cause a police crackdown on a rival gang.
- Foreshadowing: Blaine loses his taste for wine at the beginning of the episode, and is revealed to be a zombie again at the end.
- Gretzky Has the Ball: Ravi says that Major might have heard of Jonas Salk (who invented the polio vaccine) "if he scored a touchback for the Huskers."Major: Or a touchdown for the Huskies.
- Internal Reveal: Liv finds out that Gilda is Rita, but does not finds out that she works for Max Rager.
- It's All About Me: Cher is up to steal money, manipulate and get her boyfriend arrested, kill her mom, screw over the employees of the coffee and sell the shop to Stan, just to get her trip.
- Lampshade Hanging: Liv remarks on how weird it is that it took this long for Major - who she was getting pretty serious with for several episodes and is a major person in her life regardless - to meet her roommate "Gilda" - who she's been living with since the start of the season. The audience has been awaiting this event ever since Gilda was revealed as the roommate, and especially since Major started hooking up with her.
- Love Makes You Dumb: Lampshaded by Cher, as she convinced her boyfriend to take the blame for the victim's murder.
- The Mole: Drake is revealed to be an undercover cop.
- The Pollyanna: Leslie, and by extension Liv after she eats Leslie's brain. It's why she's hesitant to buy Cher as the villain even after her visions show a strained relationship between Cher and her mother Leslie, allowing Cher to get away with it.
- Pop-Cultural Osmosis Failure: Ravi loses interest in the barista he's been flirting with when she reveals that she's never seen Star Wars.
- Pretty Fly for a White Guy: Gilbert, Cher's hipster boyfriend, is obsessed with French culture, speaking with a faux-French accent and plenty of Gratuitous French and pronouncing his name as "jil-BEHR" rather than "GILL-burt", despite being the son of a realtor from Bellevue.
- Properly Paranoid: Based on the timing of her arrival at the police station to stop Gilbert from giving her up, Cher must have already been assuming he would do that from the moment he got arrested. She was right.
- Rise from Your Grave: Blaine does this at the very end of the episode, after Mr. Boss slits his throat and buries him in the middle of the woods.
- Self-Made Orphan: Cher, who killed her mother.
- Shipper on Deck: Having imbibed Leslie's incredibly upbeat brain, Liv turns into one. Of course, she's absolutely indiscriminate and basically ships everyone with everyone and assumes it will work out regardless.
- Shout-Out:
- The title is a reference to the movie Eternal Sunshine of the Spotless Mind.
- The subplot involving Blaine and Mr. Boss has several Chinatown references.
- Liv references Singin' in the Rain while talking about how wonderful rain is.
- The Sociopath: Cher.
- Status Quo Is God: Blaine reverts back into a zombie.
- The Unreveal: Once again, Liv comes close to the truth about Rita, only to fall short. She learns Rita had slept with Major, but concludes that she was a sick bitch, and doesn't learn she's a Max Rager employee.
- Your Head A-Splode: Leslie's head gets splattered by an AC unit. Liv winds up having to pick pieces of the sidewalk out of her brain.
