this is interesting and disturbing.

This is excellent. So in character, and the imagery is excellent, really disturbing in a good way. I look forward to more.

Oh wow. This is very, very good. So there are others who see the Knives/Vash implications. ^_^ I'm interested in where you take this, because finding good KxV (i.e. that keeps them both in-character and has the relationship as abusive and fucked-up as it is rather than OMG INCEST ROX SQUEE FLUFFYBUNNIES) is really hard.

Write more if you feel like it, because this is definitely one of the better fics on at this time. I'm waiting to see where it goes, which is more than I can say for a lot of fic. ^_^
