Piece of mind ()

After colliding with debris on a prog-speed lane, John, a time-traveling scientist, and his robot companion, Orb, crash land on the deserted planet of Ganymede-003. John knows the only way to escape is to disassemble Orb and build a communication device, and while he refuses to do this, Orb insists he does. After a fatal wound, the question of whether to save himself, or let his friend live on becomes pressing, but who's life is more important, and is Orb even alive?
