Jin couldn't agree more. A good rival is the best thing for honing one's skills. Even if he's not on the best terms with his normal rival these days. I vote the backstabbing comes in the form of a PR battle as each tries to convince everyone else that the other is really a villain without outing himself.

Oooooh, you know Xenosaga? That's rare. And this isn't just any Jin, this is a mirrorverse Jin who is the commander of U-TIC, as anti-Federation as they come and generally all around untrustworthy. Slightly more moral than Margulis but much more willing to set aside his pride and do things the quick and dirty way.
