Good point,a lot of them are unknown.But are main man Cedric was cool,and of course Harry's beloved mum was a Hufflepuff.So those two are my fev. Huffs.And I always thought of Luna as more of a HufflePuff than a Ravenclaw.I'm not sayin' she is not smart,I'm sayin' that to me she seems like a more sensitive person,kind,warm-hearted,loyal,BRUTALLY HONEST and all around sweetheart.In other words a true HufflePuff.
