And speaking of disturbing, when Cassandra is too weak to go on, the team finds a safe place to for her to lie down ... and perhaps die. But when Murphy privately says his goodbyes, Cassandra seems deeply ... well, disturbed by the zombie messiah.
And then the team finds this guy, who was once the very attractive quarantined doctor in the flashback with Dr. Merch. He shows them the video of how he came to look like this and then begs them to kill him.
Citizen Z utilizes his super-technology to discover the truth: the REAL Dr. Kurtz holds the patents on the world’s worst diseases – THIS guy, Dr. Walter Kurian, is the man responsible for the outbreak itself.
Wait! What's happened to Cassandra? Is she zombified? Or does the bite mark on her cheek mean that Murphy is controlling her? Either way, she saves the team from the soldiers accompanying the evil Dr. Walter Kurian.
Noooo!! Not Doc! He's a real favorite, right? He got stoned with a zombie in an elevator! He always has sage wisdom to share! He's the only father figure that 10K has anymore! Noooo!!! (Actually, it's cool, he lives to see the closing credits ... but close call, no?)
It turns out the facility is linked to a system that causes a nuclear missile to be shot straight at it if anyone contaminated leaves the premises. Worse still, one missile begets other missiles. The apocalypse just got a lot worse.
