unless its infinite?

When DD says he believes that Voldy had the idea to use Nagini as a 
HRX around the time she killed an old muggle man, are we supposed to 
assume that this is Frank Bryce? If so, that isn't how it reads in 
GoF. 

Voldy could be a HRX for Nagini, it would explain his snake like 
looks.

RAB / Snape, it's a ship! 

Is the secret RAB mentions in the note not the HRX secret but 
another secret altogether?

I may be as woefully wrong as Humphrey Belcher, who believed the 
time was ripe for a cheese cauldron.
