But R.A.B. seemed to know Voldemort from the letter he wrote. He also seemed to know that Voldemort would have him killed soon.
However, it doesn't seem to make any sense that Voldemort would let ANY of the Death Eaters know about hi Horcruxes. He didn't tell Lucius Malfoy and even Lestrange doesn't seem to know about it. I do just hope that R.A.B. is explained well, because right now its a very confusing thing to me...
