It's the look of revoltion and Dumb's pleading that makes me wonder that Dumb might have been Petigrew with Polyjuice (though it has been pointed out to me that Dumb/Petigrew would have to be sipping it every hour, which doesn't seem likely does it) hmmm.... some other kind of potion??? This theory needs work...

What do you think about this Inferi. What is it?? A curse??? They talked about the DeathEaters using the Inferi and there were Inferus's in the water in the cave, maybe Dumb is dead and was made a Inferus and manipulated by DeathEaters... ??? I'm reaching I know but it was something that was mentioned a couple of times and then... didn't come to much. Very sus. with our Jo... might be important later.

fishgurl: Totally agree with you. I reckon it may well be Reggie Black and that Voldy killed him in person 'cause he stole his Horcrux. Though, again, with our Jo... ?

Here's a horcrux theory: What if a horcrux is in Harry?
