I was rooting for either Hermione or Luna Lovegood but either would have given harry a good understanding of Logic or the magical world's oddities eitherway. Still I see how this will go and am anticipating them going to Hogwarts and see what bumbles Sniveling and Tommyknocker will react to the bond!
P.S. I suggest allies would quickly come up if the Trio would knock the three holier than thoughs on their arses!

I would think Snape is going to make a remark at Hermione or Daphne in first Potions class and Harry'll knock him on his can.
