Hope for the Best, Plan for the Worst (гет)

Holed up at 12 Grimmauld Place and facing charges of underage and illegal magic use, it's fair to say that Harry Potter's summer holidays aren't going well. The date of his disciplinary hearing is drawing nearer and the pressure on him is growing, but he discovers that he has one ally who's thinking clearly and knows that an ounce of preparation may make all the difference.
Which is just as well, because the rest of the world appears to have lost its collective mind!

Basically, it is written backwards from the courtroom scene later on, and suffers in the process with a bit in the middle that doesn't quite fit. Still good for a few giggles, I hope!
