So do you think he lived inside the magical world e.g. Hogsmeade, Knockturn Alley, or would he live in between muggles and wizards alike in London?
I wonder what you think about his salary- ten galleons maybe? Because if that's the case, and Tom didn't want to live in a charity room and bought (or made, don't know which) a house, then where would he have gotten the money? And how big would the house be?
About his O.W.L.s, how many do you think he had? I remember Ron unknowingly tease about it in CoS- something like "...maybe he save a teacher from the giant squid or got 30 owls..". We know getting 30 O.W.L.s is about impossible, but I want him to have more than 12 (Barty Crouch said his son just achieved 12 owls and he is very proud- GoB).
Do you think that he was already so smart that he signed up for more classes than possible to attend, but his teachers (mostly Slughorn) set up a system for him so that he only had to go to the very important ones (Potions, DADA) and just skip off the lesser ones? And when he took exams, he would already be smart enough to know everything without studying... I'm getting a bit... It's possible, he was Slughorn's class pet.
Did he murder Caractacus Burke for some reason?
