NARRATOR: Oisri Dig Base, Medical Wing...
TAGON: Well?
BUNNI: They were beyond help before you came in through the roof.
BUNNI: The nanny-cloud went straight for the central nervous system.
TAGON: How come they look all... you know, shredded?
BUNNI: Two reasons: first, the nanny-cloud used its targets for material in order to replicate.
Second, the attack on the central nervous system caused muscles to spasm at full strength, breaking bones and tearing damaged skin. Roddy and Wick died in a lot of pain.
TAGON: Now tell me why this room isn't full of flesh-eating nanomachines.
BUNNI: You mean grey goo? They probably have hard-coded limits on replication and life span.
I'm just guessing, but I think whoever designed this stuff wanted an anti-personnel weapon, not a minefield. They want to be able to move in after it's finished.
They also didn't want any witnesses. You get hit with this, your brain is lost to us.
TAGON: Roddy, Wick... goodbye, guys. I'm sorry I let you down.
SCHLOCK: So... can I have their stuff?
