(He) looked rather like an old lion. There were streaks of grey in his mane of tawny hair and his bushy eyebrows; he had keen yellowish eyes behind a pair of wire-rimmed spectacles and a certain rangy, loping grace even though he walked with a slight limp.
Jo *from my knowlade* never actually stated that this was the half-blood prince. It could very well be the DADA teacher. Also on her website if you look at the "Extra Stuff" section. There's alot of background on Dean Thomas although she said his history might not ever make it into the book, but she had planned to put it in the CoS. Didn't she clearly state that it was supposed to be in CoS Then later added. "Stop reading the Chamber of Secrets...blah blah blah..you won't find it in there" or something along the lines of that? Also..we do not necessarily know that the Half-Blood Prince means someone who is a half-blood. It could mean anything...of course I dont know :/ but w/e 6 more days until we know for sure
Who do i thinki could be the half blood Prince. Colin Creevy is one name that comes to mind because he is in Cos a lot but afterward isnt brought up to much and jk said that there were conections to cos in this book. But even more than that i believe it is......Hagrid. I didnt come up with this myself but on another site it said that Hagrid is Half-giant and half-wizard[half blood] and if i remember correctly his mother was a Queen Giantess so that would make hagrid a Prince...so Half-Blood Prince. Makes sence. but also i think it was said somewhere that Half-blood prince could mean anything.
