I think that Snape is the one who will defend and protect Harry 
until the end. There is a reason that has not been revealed yet. It 
seems that whenever Harry is in trouble or danger Snape is there but 
Harry always comes out okay. As for the half blood prince; in The 
Order of the Phoenix wasn't the prophecy that there were actually 
two boys born in July; so would it be logical to think that maybe 
Neville is the half blood prince? Or should I read OP again? Please 
respond. Thank you.
