"You sure your ancestors won't be offended by my wearing this?" Hermione asks softly.

While she waits for his answers, Hermione concentrates on her happiest memory, which include the first time she got a potion right without Severus correcting her, and the romantic interlude that she just shared with Draco.

Her Patronus, which is still an Otter, forms quite solidly with the happiness that she was able to manifest. It swirls around, waiting for instructions.

"I need you to get a message to Harry." Hermione thinks of him first, naturally. Not only is he an Auror, but he is still a good friend. "The Morsmordre spell has been cast by Rutton. Send a support team."

The Otter Patronus flew off to deliver the message.
