Forget about Chad, Numbuh 19th Century was the real martyr. Served loyal for his entire tenure, became valued and reliable enough to be trusted as a pivotal piece in one of the most important operations of his time, and when it goes ploin-shaped, he gets the worst of it and is trapped for near a century, his family and friends all moving on and dying, never knowing what became of him.
Then when gets woken up, and dragged into the middle of another conflict in the name of the KND, what does he get? Mindwiped and left fend for himself, a stranger in a strange land. What a fine recompense for heroism.
