Had another thought on who might die. I keep going back to the fact 
that we've been given the info that house elves have a powerful magic 
of their own and Dobby's really fierce love for Harry Potter, sir. We 
keep thinking of all of Harry's friends as candidates for death, but 
what if it's Dobby? What if Dobby provides a key piece of the end? 
Loyalties that Harry has from showing mercy (Dobby and Wormtail) could 
easily be a big part of how his ability "to love" (keeping in mind 
mercy and compassion can be types of love) helps him survive where LV 
has only slavery by fear. Thoughts?
