Matthew's Journal

The Leaky Cauldron has revealed more evidence suggesting that Sirius Black's brother, Regulus, is the enigmatic "RAB" from Harry Potter and the Half-Blood Prince. The Dutch version of Harry Potter and the Half-Blood Prince was released, and the identity of the character is translated as "R.A.Z.". The name Sirius Black is translated as Sirius "Zwarts", with a "Z". Apparently, a similar occurrence was observed in the Norwegian version of the book as well. To me, this stands as one more clue in the strong case that points to Regulus Black as R.A.B..
