Dung:
No, I meant what Pippin said. Nobody can be sheltering R.A.B. with 
DD's knowledge, or DD wouldn't have gone haring off to the cave.  
*If* someone has been hidden and their death been faked then I think 
it's ... Um. I'm Sorry I haven't a Clue. It could be that she wanted 
the line taken out to stop this kind of speculation altogether 
because it's confusing, rather than too big a tip-off. 

I *do* think RAB is Regulus, boring though it is. I suspect the 
realisation will come at Grimmauld Place when they finally get that 
tapestry off the wall, and it will be the first inkling Harry has 
that Sirius might have been wrong about something. Or someone.

It could be, as Alla suggested that Regulus is alive anyway, being 
hidden by someone else (Snape! Snape! Snape!) but ... I remember 
thinking my way through all of this last time, when we first 
discovered there was a discrepancy between editions, and I'm not 
sure much has changed. So I'm going back to my original Regulus is 
dead hypothesis, and ironing my hands in an attempt to teach myself 
not to click 'send' before engaging brain.
