you can push any npc by kicking them. kick him to Won's door.



make sure he's on this side of the door:



kick the door. sometimes when first kicking it, the door won't open, and kicking it again may push Vlad back a little. when this happens, just kick him back in. kick the door, and bam! he should be dead.



nothing happens after, though. there will be no game-over screen, no character will react to this, not even an easter egg will appear, and when you head back from a different universe or the outside world, he will be alive again.
