Chapter 23 Pt 2 - The Devil's Workshop

[Eviebae]

On Lizzie's recording, it sounded like after a few growls, the zombie said, "move." (...) As far as Lizzie goes, I'm afraid to say it, but I believe she, along with Bricks, Tardust, Scratch and who knows who else, are on thier merry way to the Colony.

Or more likely being taken to the hospital. That's why you hear the zombies up close and personal in the recording.
