Liv investigates the apparent suicide of a mental patient, while Major does some investigating of his own into the existence of zombies.
- Bad Boss: Blaine stabs one of his mooks' throats when his supply of Alan York's brains are taken by Major.
- Bath Suicide: Scott's murder was made to look like one.
- Brick Joke: There's a news report about the astronaut who was mentioned a few episodes ago. He's gone missing.
- The Ending Changes Everything: Liv was hallucinating the Johnny that was hanging out with her and the Major she confessed to. Which doubly sucks since the real one barges in with bags of brains, telling her that zombies are real... and he's going to hunt them down.
- Foreshadowing: There are a couple of hints early on that "Johnny Frost" isn't really there. The most obvious one is his repeated misreporting of the weather. It's the same incorrect report every single time. There's also the scene where Liv requests his help climbing through a window and he refuses. His excuse is a rotator cuff injury, but in retrospect, it's actually because he wouldn't be able to touch her.
- Find the Cure!: Ravi found the cure to the zombie rat.
- He Who Fights Monsters: What Major has become.
- Red Herring: Twofold. Soon after Liv eats Scott's brain, she hears a voice, which turns out to be that of a little devil on a packet of junk food. So we're going into haha-funny-hallucinations, with only a little side-order of creepy when her detective friend sees her argue with a snack vendor. Nope - those are only distracting you from the real hallucinations, which are a) Johnny Frost appearing by her side (still comical) and b) her imagining patching things up with Major (with an utterly tear-jerking reveal afterwards).
- Side Effects Include...: Liv eats the brain of a drug dealer, can't expect less from it.
- Shout-Out:
- "Hey, I don't have to tell you not to talk during Vertigo, right? I don't want to hear about how any of the deaths are scientifically inaccurate."
- "So I'm gonna guess that no one's gonna let me watch Harvey, either? Some real Jimmy Stewart haters here."
- Houston, we have a problem.
- "It's not going to be The Dark Side of the Moon cold, but, yes, we are definitely in for some sweater weather".
- Liv's hallucinations resemble those experienced by the protagonist of Wonderfalls, right down to their cryptic nature and the use of a gruff-sounding voice actor, and the fact they come from inanimate objects. The hallucination even has an "I told you so" moment similar to what Jaye in Wonderfalls occasionally experienced.
- Show Within a Show: Peyton comments that she and Liv are fans of a zombie show named "Zombie High".
- Through the Eyes of Madness: What Liv goes through after eating Scott E.'s brains.
- Wham Shot:
- The Johnny Frost Liv has been talking to was all in her head. So was the Major she confessed to.
- The zombie rat is back to normal.
- What Have I Become?: When Liv finally opens up Scott E.'s phone, she finally sees how she looks in Full-On Zombie Mode.
