What else?

The first thing she wanted to do was chase away Harry's problems. Of course, she could not write that. She had to think it through first. She did what she always does: she made a list.

1. Chase away the toad woman.
2. Make the ministry acknowledge the return of Voldemort.
3. Vanquish Voldemort.
4. Clear Sirius' name.
5. Make Harry relax.

The first one was easy enough, but she was feeling vindictive. She could easily make the toad woman not exist at all, but it would not bring justice to her crimes.

Delores Umbridge could speak nothing but the truth.

She stopped at that. She could not be naive enough to think that the truth would bring her to justice. It would make her life uncomfortable, but she no longer believed in authorities.

Delores Umbridge could speak nothing but the truth and is so magically weak that nobody respects her.

Delores Umbridge cannot consume anything in Hogwarts.

Delores Umbridge does not feel safe in Hogwarts, and her paranoia is higher than that of Alastor Moody.

Delores Umbridge has the habit of revealing everyone's secrets.

Hermione put her quill in her mouth. While this was good enough, it needed something more.

Karma has come for Delores Umbridge. She will feel the result of all of her actions.

Now she felt it was good enough. She looked at the clock and sighed. It was late. Maybe Harry went back to his dorm after the detention ran late. She decided to call it a night. She will need to see the result before making further plans.
