Ebonies are highly specialized dittos that are good at intelligent data analysis; platinums are only used by the very rich, and closely resemble real people.

The second gray gets involved in a plan to infiltrate Universal Kilns to see if they are illegally withholding technical advancements to the duplicating process.

He is a dupe of unknown forces, and is actually carrying a bomb into the UK factory, but he realizes just in time and manages to minimize the damage done when he blows up.

The green comes out of the kiln and starts doing the chores he was made to do, but soon displays a lack of motivation to complete his assigned tasks and instead heads off to the beach.

Once there, he decides that he is an imperfect copy of Albert, or a "frankie" (a fictional slang word derived from Frankenstein's monster).

On the way to investigate Yosil's cabin, where the eccentric scientist spent much of his time, they both are made aware of an attack on Albert's home.

The green and the real Albert join forces to destroy the apparatus and disable the bioweapons that would have been used in an attack on a nearby city.
