A dungeon master keels over in the middle of a game of Dungeons & Dragons. Two of the players work at the police station: the Goth IT guy and the Jimmy the sketch artist. Everyone at the game is a suspect, as the deceased's wine is revealed to have been poisoned. Liv eats his brain and starts narrating everything, while deciding all her actions with a 20-sided die.
Meanwhile, Ravi attends the anti-zombie meeting. He claims to be working on a vaccine in order to keep the group from attempting to kidnap a zombie.
Major finds all the hate mail Ravi has been keeping from him. There's one letter whose author thinks him innocent.
Liv and Justin attend the party thrown by the mayoral candidate, where she meets Chase Graves, who grills her on the investigation. A sniper shoots the mayoral candidate, causing the latter to go into "zombie mode", but Liv manages to calm him down before anyone sees his red eyes.
Don E eats a chunk of the brain Blaine has been soaking in blue liquid and can't stop his very active and vivid visions (the deceased was a World War II vet). When he runs outside, the shooting range owner captures him and puts him in a cage to show to Ravi.
Major meets the girl who wrote the letter. Meanwhile, Mr. Boss is back in town...
- Bookcase Passage: There is a secret room behind a bookcase in the deceased's home, packed with advanced computer equipment, with the screens showing blueprints to a Russian nuclear power plant.
- The Bus Came Back: Dale returns to take the dungeon master case from Clive, when evidence reveals international ties. He tries to apologize and rekindle the relationship, but she's having none of that.
- Mr. Boss also returns from abroad.
- Call-Back:
- Clive first being skeptical and then getting utterly absorbed into a fantasy universe is reminiscent of his obsession with Game of Thrones.
- As it turns out, Liv's brief dominatrix fit has deeply affected the sketch artist, who drew her in a leather outfit with a whip.
- Conspicuously Public Assassination: A sniper somehow makes it into the building, where the party is taking place, and takes a shot at the mayoral candidate, presumably in order to reveal him to be a zombie in front of cameras. Luckily, the wound is clearly non-fatal, even for a human, and Liv is able to calm the enraged zombie candidate before anyone spots his red eyes.
- Disappointed by the Motive: For most of the episode, Clive and Liv assume the motive for the murder is either jealousy (the deceased was sleeping with a girl other male players liked) or revenge (for killing off the players' previous characters). Then, out of nowhere, they discover that he was also involved in what appears to be espionage and was likely killed by a foreign agent. Not only does this not fit with the rest, but Clive also loses the case, as it has now become federal.
- Fantastic Drug: Brains soaked in the blue liquid are treated as this. Don E ends up overdosing and starts acting crazy, unable to shake the vivid visions of a World War II aerial dogfight. He also goes into "zombie mode" right in front of a couple of the anti-zombie guys, who capture him and put him in a cage.
- Fastball Special: During Liv's game, the party is fighting a lich, who's high above the ground. In desperation, Major has his character (a human paladin) toss Clive's character (a dwarf) at the lich. Clive then attacks the lich and succeeds.
- Fate Worse than Death: Blaine occasionally visits his father in order to talk to him and toss a few brain chunks down the well, so that Angus doesn't go into a permanent zombie state. He seems to really enjoy tormenting his father.
- Female Gaze: The camera slowly pans over Major's abs and chest during his Shirtless Scene.
- Game Master: The deceased was an avid dungeon master. Liv becomes one after eating his brain. She even recreates a game with Ravi, Major, Clive, and Peyton in order to trigger a vision.
- Goth: The Goth IT guy makes a comeback, having been present at the dungeon master's death. As such, he's one of the suspects. It's revealed that he only became Goth in order to impress a girl.
- Instant Expert: Liv once again shows that eating someone's brain imparts some skills, including knowledge of D&D and the ability to read Russian.
- I Resemble That Remark!: For someone, who is most definitely not a nerd, Ravi sure knows a lot about D&D.
- Killer Game Master: The victim killed all the players during a previous campaign, under apparently unfair circumstances. Liv, after eating his brains, follows suit and tries to kill Peyton's character after the game has barely even begun.
- Offscreen Moment of Awesome: When Blaine's crew tests a World War II veteran's brain soaked in blue liquid, there are descriptions of epic battles against the Nazis. These are never shown.
- Off the Rails: Attempted; at the beginning of Liv's game, when offered a reward for going to a castle and taking down a lich, Peyton suggests just tying up the questgiver and stealing the reward from her, thus avoiding the whole danger of fighting the lich. This backfires when the questgiver turns out to be a powerful mage who almost One Hit Kills Peyton's character for her trouble, with Ravi barely saving her.
- The Password Is Always "Swordfish": Averted. The deceased's computer in the secret room fries after a single incorrect password entry.
- Shout-Out: Liv calls her players the Fellowship of the Dorks. (The sarcastic name is coined by Peyton when she thinks her character just died).
