Narcissa had a quick bit of small talk with Griselda Marchbanks, and the gossip was quite illuminating. She seems happier since resigning from the Wizengamot in protest of Umbridge's becoming Hogwarts" High Inquisitor and is now in charge of the Wizarding Exams Authority. And that means Tiberius Ogden's reinstatement makes him the ranking member of the Wizengamot, a well-known supporter of Albus and Harry Potter... he can help Hermione's goals in rebuilding the Ministry. The Slytherin smiled inwardly, knowing that this intel would be well-received by her wife.
