This entry shall contain spoilers that relate to Harry Potter and the Half-Blood Prince.
That's right, mothafuckas, spoilers.
I've been thinking about RAB. Me and Katie have pretty much only guessed Regulus Black. Since that is the only known character with the initials 'R' and 'B'. No one knows, except J.K. Rowling of course, the middle name of Regulus Black. I ran into a Harry Potter forum and heard some people speaking off 'Aberforth' being Regulus' middle name. Highly unlikely. But I found this interesting post by a bloke named 'barkley':
"SPOILER (On a Tale of Two Cities by Dickens, just in case you have not read it!)
Do any of you remember a "Tale of Two Cities" where a less than reputable man named Sidney Carton looked identical to the guy who was in love with the heroine of the story (been a while since I read it, can't remember his name)? Anyway, Carton stepped into the shoes of the other guy, who was about to be hanged. He ended up dying in his place, allowing the lovebirds in the story to return to England and lead productive lives, and no one else knew of his sacrefice.
Now, would it not be interesting if a character we know and love but would hate to see die, had a brother. Sometimes brothers resemble each other. What if the person WE THINK died smelled strangely of goats?
I have not read the books and this is speculation. But I really don't think Regulas Black's middle name is important. (thanks for the clue R.A.B.) I guess we'll know in a few hours."
Aberforth is Dumbledore's brother. Dun dun dun!
