i think it makes perfect sence..the deatheaters do take help from others mostly forcing them to do things for them just as rab wood do to kretcher..but kretcher wood love to help his master he hated serius and mugbloods sure he even tryed help drago so it makes sence he wood help regulas..the deatheaters are not like voldy hes the only person that dosnt trust anyone and likes too work alone..i would be really surprised if kreatcher didnt have some part to help in retreving the locket

OK Sevrus say the the DE's are like the KKK well they wouldn't be below forcing people they consired BELOW them to stuff they are (not scared) not weary of doing like not knowing wether the potion would kill you or drive you insane so force someone else to do it (KREACHER) then reap the rewards for yourself

everyone bleave what ever you want I'm sticking with my therory, you all will eat your words by the time the 7th book comes out or I will hopefully not but ya never know so ya

what is your theory? i think this one makes sence but it could be a bit too easy to pick up so we'll just have to wait and see wat happens in book 7 haha

My theroy on what topic I have loads of theory's regrading HBP

RETIGULAS BLACK DUH

Well first off I don't beleave he was alone, the name R.A.B does not symbolize a name more like a group ie-Regulis/Avery/Bella thats my theory. it just fits now please don't say LV would never trust anyone to tell anyone about the basin, well I have another theory on that ie-Lv always kept a diery well Lv has to sleep sometime I don't think he would want a gaurd not even his snake rember he works alone so they could have stolen it.

First of all I think that RAB stands for a motto, pledge or oath taken between someone and Voldemort. RAB stands for a saying of some sort that is known ONLY between Voldemort and the person who pledged the oath of loyality.

As soon as Voldemrot sees RAB he will know exactly who this person is and who betrayed him. And this person could be so close to Voldemort that he is the only one LV could trust because this person is his own blood.

Regulus is a fine guess, as JKR stated herself, but it also seems a bit to easy. Regulus Black, R.A.B., and the locket most likely being the one from #12 make this an almost too easy fit.

However, to the casual reader of the books, they may not pick up on these little tidbits from JKR, so I still want to believe it all fits, I'm just having a hard time with it.

How was he able to do it alone? I personally don't think he was able to, as Dumbledore wasn't able to and he is the greatest wizard of the time and had defeated the previous Dark Lord. R.A.B most likely had to have someone with him, Kreacher is a really good guess and I love that theory. That could also be why the locket was back at #12 as I don't believe Regulus. would've lived long enough to have brought it back, nor do I think he would've wanted it to be at the house of his family. That would put his family in danger, in my opinion, and unlike Sirius, Regulus seemed to love his Mother and Father.

One of the main issues I have with it being Regulus is that he was only 18 at the time of his death. How could an 18 year old, even with the help of a House Elf, have gotten through all the barriers that Voldemort put up in that cave? I believe he was smart, as alluded to by Slughorn in HBP, but he would have had to have been exceptionally brilliant to have gotten through them at the age of 18, in my opinion.

I don't believe multiple Wizards were involved in retrieving the locket because the note was written to much from a 1 person perspective. "I" was throughout the note, in fact 7 times. Now this could be a red-herring from JKR by using "I" instead of "WE", but I think that would be a big stretch for her and very uncommon. Her red-herring's are brilliant, but I just can't see her throwing the "I" around so much without it really being a 1 person deal.

I really want to believe that Regulus is the person, but I'm having a hard time due to his age and the fact that JKR used Half-Blood Prince as another name for Snape. Just like Lord Voldemort had another name "Tom Marvolo Riddle". She could've possibly used R.A.B. as another name of a close Death Eater and we just don't know about it yet.

Whoever the person is that wrote the note, it appears to me it had to be a Death Eater and somebody that is already dead. Only the Death Eaters call LV "The Dark Lord" and the note is telling us that the person is most likely dead. There is no way of telling when this person died, it could've only been a few months before Harry and DD went to the cave, it didn't have to be 15-16 years ago. Of course that is only likely if the Locket at #12 is not the real one, otherwise it still didn't need to be 15-16 years ago, it could've only been 5 years ago.

I couldn't locate in OOTP how long the locket may have been at #12, was it ever stated? If so, could someone give me the page from the US Hardcover?

Yes, it's a fine guess but is it the right guess? I son't think so.

The only people at the cave was Harry and Dumbledore. They are the only two who ever entered the cave and Dumbledore is the only wizard who could get through Voldemorts defenses. Therefore sonce it was Harry and Dumbeldore who were at the cave that means that the locket in the basin was the real locket and not the fake. The real one was stored inside of Dumbeldores robes and he had to have had it on him when he was on the tower. If that is the case then it was also on his body as Snape AK'd him and as his body fell to the ground. Somehow during that period of time the locket was stolen and the fake was placed by Dumbeldores body. And it was done in a hurry as the fake locket was left open when RAB fled.
