As for RAB, there's a new theory going around that there's no way Regulus could have gotten the Horocrux alone (DD couldn't do it alone even), and the other person with him would have the same initials (or it's a combo of their initials). So I think the theory is that it's Amelia Bones who was with him.
BTW, this is a ridiculous theory. Like our "
simplytruly outrageous" friend pointed out, his name had to be translated in foreign versions and they changed the initials accordingly.
Ah, thank you. I was more of a He-Man/Transformers/Thundercats guy. I think if a dude watched Jem he'd be promptly dropped (not like he was hot, though).
