The Titlings

Hi, I'm Chris from Indonesia, I've joined this group for more than 6 
months but this is actually my first post..lol.

Anyway, there somethings bothering me, the titles of the books.

Sorcerer's Stone : a stone that lead Harry to meet Voldemort for the 
first time.

Chamber of Secrets : a hidden chamber where Slytherin and some of his 
selected pupils practice the dark arts, or something like that.

Prisoner of Azkaban : a man that turns out to be Harry's godfather.

Goblet of Fire : a goblet that turns out to be a portkey and brought 
Harry to meet Voldemort, again.

Order of the Phoenix : a group of people lead by Dumbledore to 
against the dark lord.

Now, we know that the next title's going to be 'Harry Potter and the 
Half Blood Prince' which seems to be like a pattern:

SS,GF : an item that brought Harry face to face with Voldemort
CS,OP : a place or group of people in which the people, if not pros, 
against the pureblood idealism
PA : a man that's related to Harry

If this pattern is true and I don't make mistake on drawing the 
conclusion, then this halfblood prince would surely has some relation 
with Harry also.

We do know that every title brings up new items, place, group and 
character, which mean this halfblood prince is someone who's not our 
well-known character. Short to say, he might be a whole new character.

But wait, Sirius was introduced in the first book at the very first 
chapter and yet brought under the spotlight after the third book. If 
this is also a pattern, would that mean who ever this halfblood 
prince is, he was already mentioned in the third book and later 
brings to the attention in sixth? Would he be the replacement of 
Sirius after his death?

waiting for reply,
