-Chuckle- My, Dumbles definitely fits the definition of insanity, he failed with Tom and Harry and now he wants to try it again with Neville? Given what Neville's learned from Harry, I daresay that's going to prove to be a very, very bad move. I reckon Hannah may not like Dumbles' opening moves but I'd hazard a guess that Neville will deal with that and, then, Dumbles will have both an angry Harry & family and an angry Neville & close associates after him and the two groups likely closely allied.
Meanwhile, it seems that Ron is being especially stupid. He's been told to stay away and he's still tried to make a move after his Head of House specifically told him not to. Methinks his days at Hogwarts are rather numbered and I doubt Ginny is going to be there much longer than he will be. Molly doesn't realize, yet, just how much "judgement" is going to be visited on her. We know the twins are very ticked-off (to put it politely) and I rather imagine that Arthur is going to be horrified. Not to mention what's going to happen to her should she confront Harry/Hermione/Daphne. If -only- the trio hurt her, she'll be lucky. I'd guess that her marriage is going to be very much in the balance as Arthur may have his excentricities, but he's an upright and honorable wizard and he's going to be quite upset at the slur his wife and two youngest have cast on the family name.
I think it's just, -finally-, coming home to Tonks just how badly she's stepped in it. Not only has she lost her job but she's essentially committed treason against her Head of Family. If her mother doesn't manage to work a deal, she's in a very deep mess. I rather suspect that Harry & co. and Andromeda can work something out, but I daresay it's not going to be pleaseant for Tonks.
Tom continues in his underestimating of Harry. I still say that just because Harry doesn't wantonly kill doesn't mean that he won't when he needs to, especially since he now has two very special witches to care for an protect - though I daresay that they'll -firmly- reject any protection that doesn't let them fight alongside him; he'll firmly lose that battle if he tries it.

Neville is going to be a most angry young man... His Gran even more so, only without the young man part.
Ron has just made the second largest mistake of his life. The largest (and possibly last) comes next chapter.
For Arthur's reaction to Molly's involvement, check out the next chapter.
Tonks is going to be thankful and horrified by her punishment...
I'm not sure, but I believe I have the single most original fix for the Tom Riddle situation ever put in a fic... Wait, no I don't. The most original was a fic who's name I can't recall that had Harry and company holding a Triwizard Tournament on the QT and enrolling Tom without bothering to tell him about it, and he lost his magic when he didn't compete. Ok, so mine is the second most original ending...
