As opposed to stupidly reckless and wiping out everyone. Maybe if we're past it, you shouldn't jump at the idea of telling me all the reasons why purebloods are bad.
I'm saying because compounding the problem and adding stupidity to more stupidity, let's consider the options we have. Hogwarts seems to be in charge at the moment and if we go back, does it mean that it'll bring others? Also why so many Blacks? Five of us are direct descendants. Lupin is the one that breaks the pattern. IS there a reason? What's different about him? There's so much we should find out before a) trying to go home or b) trying to get your friends back.
