*can't believe there hasn't actually been a thread about him*
Well, I'm not really sure about Stan's history. Harry describes him as a teenager. Do you think he's fresh out of Hogwarts at that point? Maybe trying to make some money, and then never leaving? I think he's still there in OotP, isn't he?
Or do you think maybe he dropped out of Hogwarts? Failed his OWLs, perhaps? He doesn't seem to be the sharpest knife in the toolbox, if you know what I mean ...
So, yeah, if someone could speculate about his history for me, that'd be great.
