Ep 2. Blue Bloody

In the second episode of iZombie season 4, titled "Blue Bloody," Liv consumes the brain of a billionaire philanthropist named Seymour "House" Levitt who has a knack for solving mysteries. This brain gives Liv a superhuman level of intelligence, allowing her to decipher clues that the rest of the team miss.

With Liv's heightened intelligence, the team begins investigating the murder of a wealthy woman named Lila whose body was found in her mansion. The initial suspect is Lila's husband, but as Liv examines the crime scene, she discovers a clue that could point to someone else entirely.

Meanwhile, Major continues to work on his job with Fillmore Graves. His team is tasked with rounding up and executing all the remaining zombies who have not taken the cure. Major has a difficult time with this because he knows many of the zombies personally, but he believes that it is better for the city if everyone takes the cure and is no longer a threat to humans.

Elsewhere, Blaine is starting to show strange symptoms that could lead to zombies losing their memories. Don E. notices these changes in Blaine and becomes worried for his friend. He seeks out Ravi to ask for help and the two of them come up with a plan to try and slow down the memory loss.

As the investigation into Lila's murder continues, Liv and Clive discover a shocking connection between the victim and Seymour Levitt's estate. They quickly realize that the murderer may not be who they thought it was, and the case takes a surprising turn.

In the end, Liv's intelligence returns to normal, but she manages to solve the case with the help of her team. Major, on the other hand, struggles with the morality of executing his zombie friends while Blaine's memory loss continues to progress. The episode ends with a cliffhanger, leaving viewers wondering what will happen to the characters next.
