> Most people are saying that Harry's last hope for fighting You Know
Who and disarming the Horcruxes is Bill.  I don't get it, where in all 
the books does it say that Bill is skilled in the Dark Arts enough to 
teach HP how to fight Voldemort?

Ceridwen:
People are mentioning Bill Weasley because, since the beginning of the 
series, he has been a professional curse-breaker for Gringotts Bank.  
He is skilled in curses placed on ancient tombs and treasure stashes, 
the sorts of curses Voldemort might use to guard his Horcruxes.  There 
is some reason JKR made Bill a professional curse-breaker, and now it 
seems as if the protective curses surrounding the remaining Horcruxes 
may be the reason.
