Fic Rec: Weapon K

Just a quick ficrec here, as I spent most of my spare time today working on a comment for the mfu_canteen post "Illya as Cutter?", which I sort of inspired with a comment on tgabrielle 's Summit Five Affair review.

Anyway. The rec: Weapon K by C Wehst on File 40. Slight X-Men crossover; I'd have written this fic myself if it didn't already exist. Summary: Ever wonder what happens to all of Illya's scars?
