Such as how did Sirius find out that Regulus had 
tried to back out from his service with Voldemort?  
I didn't really wonder about that until I read HBP.  
Lupin showed up at the Burrow on Harry's birthday 
and announced that Karkaroff's body had been found.  
He added, "Sirius's brother, Regulus, only managed 
a few days as far as I can remember."  Regulus's 
death was very likely reported in the Daily Prophet, 
and it may have been evident by the manner of his 
killing, that he had been killed by his own side, 
and it would then be surmised that he had tried to 
get out of his Death Eater contract, but how would 
anyone on the good side know exactly *when* Regulus 
had turned his coat, especially if it was only a few 
days before he was killed?  Did Regulus approach the 
Order before he was killed or is this just more evidence 
for an evil Lupin?
