Neville's right, we need to hear from Hermione. It's her and the Professor's necks on the line more than anybody else's. Other than that, well, guess Perks knows her best, and the Professor thinks it'll be all right. Hope you're right about that, Professor.

We do think the protections on the lock would help to keep her from passing on whatever she might learn here.

Don't like it a bit, though. It would help a lot if she could give us a secret of her own.
