iZombie's Liv Moore will play a little mix and match when it comes to concocting her episode 12 meal.

The undead of The CW took a dark turn through the last two episodes as Lowell's (Bradley James) death and new Max Rager secrets peppered the landscape. While Blaine's (David Anders) brain enterprise and the energy drink cover up will continue to hang over Liv (Rose McIver) like the Emerald City's notorious storm systems, iZombie will amp up the humor as it's heroine heads back to high school.

"Liv eats two brains. She eats the brain of a stoner and she eats the brain of a cheerleader," McIver said of "Dead Rat, Live Rat, Brown Rat, White Rat," according to IGN. "That was one of the most fun. There's a lot of drama happening but there's some really great humor that happens in that episode."

Some of that drama will stem from Major's (Robert Buckley) continuing investigation. In an effort to combat his alleged hallucinations, the social worker checked himself into a psychiatric ward during Mr. Berserk. Unfortunately, his "solution" only managed to help him make the leap from cannibalistic steroid users to the zombies. Truth is stranger than fiction, after all. Once he leaves the hospital, Major will start to look into Blaine's deadly deli.

"Dead Rat, Live Rat, Brown Rat, White Rat" will air on Jun 2.
