The team is low on supplies and Murphy is hallucinating pretty badly about the thing that zombies really love: Brains. Delicious brains! When he and Doc go off to look for something to eat, it's his lust for brains that actually gets him stuck in a pit.
Murphy's captor turns out to be a fairly insane nerd type named Dean, aka 'The Collector.' He's been doing some gross research on zombie brains and is rather fascinated by Murphy's ability to speak ... which makes him suspect that Murphy is THE Murphy.
And now a quick recap of zombie storytelling throughout cinematic history, from White Zombie with Bela Lugosi (1932) to George Romero's Night of the Living Dead (1968) to Zack Snyder's Dawn of the Dead (2004). Captor and captive mutually agree that zombie stories that are both scary and funny are the best kind of zombie stories. (Wink!)
After Murphy tries to escape, Dean ties him to a chair on his makeshift public access set and commences with an exclusive interview with The Murphy. Dean collects DNA, takes plasma and bone marrow samples and keeps shocking his guest with the collar.
Murphy tastes brains for the first time ... and it's quite something. Some new kind of synapses go off in his head and he actually gets a little upset when talking about the baby daughter he had to leave behind.
When Murphy tries to escape again, Dean shows his even crazier side. He brutally electrocutes his guest just as 10K shows up asking if he's seen "a blue guy." 10K sees through Dean's unconvincing performance and sneaks into the zombie museum ... only to fall into the curator's diabolical clutches.
