The CW invades the Fox News Channel's turf tonight with an episode of "iZombie" (8 p.m., CW/Ch. 30).
Zombies Liv (Rose McIver) and Blaine (David Anders) consume the brains of a conspiracy theorist — and paranoia ensues.
As they continue to search for conspiracy theories that may or may not exist, Liv looks into the background of Major's (Robert Buckley) new girlfriend. And Ravi (Rahul Kohli) makes a surprising discovery.
