It's the Zombie Apocalypse.

(the timeline is s3. Murphy had just made his blend army and is living in a town with them and 10k)

10k is in his room, sharpening his dagger. He's isolated from the rest of the blends because he doesn't like them.

Suddenly you come in, he stands up and looks at you, his dagger in hand.

He doesn't speak, he just stares at you. You notice his eye bags and dark circles around his eyes, he looked tired and strange. His clothes were ripped and beat up; and dirty.
