My Harry Potter questions and ponderings

Found this little list of questions I put together while reading the Harry Potter books for the third time through.

The first list is questions that I'd like to see answered in the last two books:

  • Why does Snape not get the defence against dark arts job?
  • Why does Dumbledore trust Snape so much? What did he do on his "first chance", as mentioned in book four?
  • Where did Harry's parents' money come from?
  • Why is Voldemort so anti mudbloods when he is one himself?
  • What about making things work just by thinking about them? No wand or words like when harry blew up Marge or made the glass disappear at the zoo. Surely if he could do that powerful wizards could make things happen just by thinking them?

    And the next list is more just inconsistencies (there's stacks more, some of which I've read on other sites)

  • How could the kids practise quidditch on their holidays if they couldn't do magic outside of school? What about Fred and George making joke stuff all the time? What about the floo network?
  • When do the kids bathe?
  • How did Tom Riddle's diary know Ginny was talking about him as Voldemort? - presumably she never would have written his name...
  • How did Dobby disapparate from the hospital at Hogwarts?
  • If Dumbledore and Moody were such good friends, how come Dumbledore took a year to recognise the imposter?
  • How come you can't apparate inside the grounds, but you can use unauthorised portkeys?
  • Why is there no mention of the thestrals at the end of book four as Harry is leaving?

    And finally, one I may just have missed..

  • Who's the head of Ravenclaw?
