oh i'm a moron i definitely already saw you wrote he's the unknown nephew lmao sorry but that all sounds so perfect to me! vash has been all over the place so whatever timeline works for you can fit in for him and he def could have saved him at the last minute during some job gone awry in the past and that's why they're buddies now. i cannot wait for koz to pull a hamlet or something on korso and vash will absolutely wanna be there for it
