Yes I agree to that mgc66. Also as to those theories to colin creevy or Justin Flinch-Fletchley... they were both attacked in COS. Well put 2 and 2 together. Lets see attacks means, muggle borns, means not half blood, means CAN'T be Half Blood Prince!! And Hagrid is a half breed. Not Half blood. Tom Riddle is it. Lucious Malfoy has his diary and if anything survived, any of his memory, Lucious will get it out. Also to Dean Thomas, she says "He story is too much like Neville's But Neville will play a much bigger part in later books." Don't get any bright ideas, they say already that Neville is pure blood. Ohh if you have any time search for Harry Potter's Future Question. Waiting for an answer
