Umbridge, the malicious Hogwarts Inquisitor whom we meet in Harry Potter and the Order of the Phoenix, is eventually put on trial for her heinous treatment of muggle-borns in cooperation with Lord Voldemort’s reign.
Ironic, considering Umbridge herself had a muggle mother.
3. Voldemort's Soul Is Forced To Exist In This Creepy State
The only one of the trio to go back and complete her Hogwarts education, Hermione attains high status at the Ministry of Magic and eventually goes on to assist Kingsley Shacklebolt (who becomes Minister of Magic after the second wizarding war) as Deputy Head of the Department of Magical Law Enforcement, and is eventually elected Minister of Magic.
Despite their loyalty to Lord Voldemort throughout the series, the Malfoy family never faces punishment, as Lucius Malfoy provides copious information on his fellow Death Eaters, helping to capture many of them.
7. The Jinx On The Defense Against The Dark Arts Position Is Lifted
With Voldemort’s death comes a sense of relief in the world. Azkaban Prison no longer uses dementors as guards and even the muggles start to notice that the world is looking sunnier again (as the dementors tend to influence the weather for the worst).
Remember those little cards Harry and Ron first traded in the Sorcerer's Stone that featured prominent witches and wizards like Albus Dumbledore and Godric Gryffindor? The trio eventually gets featured on the cards for their triumph over Lord Voldemort.
Most recently in the Harry Potter universe we’ve gotten The Cursed Child and Fantastic Beasts and Where to Find them. Now what will J.K. Rowling come up with next?
