do Voldemort and the other Death Eaters know Snape is a half-blood? cuz if they do..it's a damn miracle (well not really lol) he's even in the DE's to begin with XD makes you wonder why he was even put in Slytherin. he seems more like a gryffindor, tbh.
i know the basics of HP, i just don't remember every single tiny little detail. i have a horrible memory :/
