 I'm rather under the impression that Neville will somehow betray 
 Harry in one way or another, whether he does it conciously or not.  
 There's a part in PoA in which Harry is imagining (this is prior to 
 him finding out the truth about Sirius and Peter) Sirius killing 
 Peter Pettigrew.  In his mind, he imagines that Pettigrew looks 
 something like Neville Longbottom.  I can't help but think that JK 
 was trying to drop a hint here.  Maybe it's just me
 
Ehren: 
 I had forgotten about that dream, but if Neville betrays Harry I 
think it will be inadvertantly. I don't think Neville would betray 
his friends like PP did though. The DE's have don't to much to his 
family that he would go to their side. 

Another thing I cannot help thinking about is that Neville's wand 
contains unicorn hair. I cannot help but fear that this is a bad omen 
for Neville. 

"There's a unicorn been hurt- you seen anything?" (Hagrid)
"Always the innocent are the first victims" Ronan said, "it has been 
for ages past, so it is now." SS pg253 (paperback).

Cedric had unicorn hair in his wand (GoF, Weighing of the Wands) and 
he was definetly an innocent person who was in the wrong place at the 
wrong time. 

Also, another person who has Unicorn hair in their wand in Ron. It 
also common storyline plot in Good vs Evil stories where the best 
friend's hero dies in some sacroficial way. 

Do we know of anyone else that has unicorn hair in their that has 
died or is still alive?
