We have two stories by Mary Ann, the first of which takes place in an alternate universe / furture AU, entitled
One Soul and featuring Vin as the main character. The second is a short OW with some Chris-Buck interaction,
Silence is Golden.
In Kemmae's fic,
Close Shave, Vin sacrifices for a noble cause, with a some "vinjury" to please the h/c fans.
In JIN's latest Chris / Vin slash offering, Paint the Sky, Vin is near death after saving JD's life, and Chris confronts his feelings for his best friend. This lovely angst-fest can be found at the
M7 Slash Archive.
