Oh, one other thing, the musing of Tom Riddle bring up something I've wondered about. We know that he and Harry had very similar childhoods and that Harry appears, even in canon, to have been manipulated by Dumbles. I've started wondering if Tom had also been manipulated by Dumbles to become his "weapon" against Grindelwald, saving him from going against an old acquaintance, and when that failed and Dumbles had to take care of Grindelwald, he ended up needing a new weapon against a very angry Tom Riddle/LV.

That's pretty much where I'm going with it. It's too late to redeem Tom, but its never too late to bitchslap Dumbles.
