On a different world, a kidnapped agent awakens in a very small room. An ominous voice seems to come from everywhere, telling him of the atrocities he has committed upon the innocent people of the other superpower. The room is equipped with a pourous wall that allows the vengeful relatives of the dead as much or as little access to him as the voice permits. One of the relatives is able to reach inside the room and throttle the agent before the voice solidifies the wall.
The voice wants the agent to switch sides, which he refuses (as any good agent would). After the agent's mind is read and copied by the other side's equipment, the agent is of no further use. Given one more chance to switch sides, he refuses.
The wall is opened, allowing his fellow agents entrance. The agent figures they have rescued him, but it was all a loyalty test. Insulted by the lack of trust, the agent seeks out someone truly from the other side, asking about what he will receive by switching sides or acting as a double agent.
