It must be hard being a clone. Doubly so the cinematic sort of clone which also copies the personality and memories of the individual, not merely the physical body.

Here's an idea. Have a PC discover in-game that they are a clone. Not just a body clone, but a copy of the original's memories and personality. And the original is still alive somewhere.

Hilarity ensues!
