Ron, Harry and Hermione’s arrival at Hogsmeade
Harry Potter, Ron and Hermione decide to figure out a method to get into the Death Eater controlled Hogwarts at Hogsmeade. However, the trio triggered a caterwauling charm that made a large cat like noise and alerted the Death Eaters of a trespasser.
The Death Eaters sent dementors in the novel to search the trespassers. The Death Eaters assumed that Harry, Ron and Hermione arrived at Hogsmeade.
While the dementors were right at them, and Harry repelled them with his stag patronus, they were at the brink of getting caught. However, Aberforth Dumbledore the younger brother of Albus Dumbledore let them into his house.
Aberforth Dumbledore then lies to the Death Eaters that his cat sounded the caterwauling magic alarm and he had to defend himself with a patronus against the dementors.
Aberforth Dumbledore and the Two-Way Mirror
The Two-Way Mirror was a means of communication for James Potter and Sirius Black. Sirius Black gave it as a gift for Harry Potter which Harry Potter opened after the death of Sirius Black.
Harry Potter has been looking into the mirror whenever he missed Sirius Black but he noticed that there was someone over the mirror.
Aberforth Dumbledore earned the other piece of the Two-Way Mirror by Mundungus Fletcher when Mundungus Fletcher was looting 12 Grimmauld place.
Aberforth Dumbledore was able to see Harry Potter trapped at Malfoy Manor by the two-way mirror so he has sent Dobby for the rescue.
Harry Potter became angry when he noticed that the two-way mirror was at Aberforth Dumbledore’s possession while Aberforth Dumbledore struck back with how he got it from Mundungus Fletcher.
Aberforth Dumbledore also bashes into Harry Potter if he didn’t had the two-way mirror, he would have been sitting ducks at the Malfoy Manor.
Aberforth Dumbledore’s persuasion of the trio
Aberforth Dumbledore persuades Harry, Ron and Hermione to escape Hogsmeade and told the trio that he thinks the Order of the Pheonix is over and admitted Voldemort’s victory.
Harry Potter argues that Albus Dumbledore counted on him to destroy all the horcruxes of Voldemort but Aberforth Dumbledore asks why Harry Potter must do so and asks if Harry Potter knew anything about Albus Dumbledore.
Harry Potter stutters and listens to the stories of the Dumbledore family from Aberforth Dumbledore.
Dumbledore Family
Albus Dumbledore was the first son of Percival Dumbledore, his father and Kendra Dumbledore his mother. Aberforth Dumbledore was the second son and Ariana Dumbledore was the youngest daughter of the Dumbledore family.
Three tragic accidents have split up the Dumbledore family which portions were described in The Life and Lies of Albus Dumbledore written by Rita Skeeter.
Muggle attack on Ariana Dumbledore & Imprisonment of Percival Dumbledore, Albus Dumbledore’s father
While Ariana Dumbledore was six, she was attacked by muggles that feared her using magic. Ariana Dumbledore lost her mind and became extremely mentally fragile and developed an obscurus inside her. Furious on the attack on his daughter, Percival Dumbledore attacked the muggles and was imprisoned into Azkaban.
Percival Dumbledore didn’t defend himself because if the fact that Ariana Dumbledore developed an obscurus was revealed, she would have been sent St Mungo’s Hospital and locked up permanently as an obscurus poses an extreme danger. Percival Dumbledore unfortunately passed away during his service in Azkaban.
Death of Kendra Dumbledore, Albus Dumbledore’s mother
After Percival Dumbledore was imprisoned, the Dumbledore family relocated to Godric’s Hollow which was a relatively peaceful village so they could look after Ariana Dumbledore unnoticed from others.
However, the uncontrollable obscurus within Ariana Dumbledore caused an explosion one day that killed Albus Dumbledore’s mother Kendra Dumbledore. Ariana Dumbledore became even more mentally unstable after Kendra Dumbledore’s death and Albus Dumbledore
Ariana Dumbledore – younger sister of Albus Dumbledore
Ariana Dumbledore was the only daughter among the Dumbledore family. She was jumped by muggle boys when she was six while practicing magic.
After this muggle attack, Ariana Dumbledore was never able to control magic properly and developed an obscurus which was a dark magic energy produced by the repression of a young witch or wizard’s magic.
Kendra Dumbledore was killed by a sudden leash of energy by Ariana Dumbledore and Percival Dumbledore was imprisoned in Azkaban for attacking the muggle boys that assaulted Ariana Dumbledore.
Ariana Dumbledore was also tragically killed during the brawl of Aberforth Dumbledore, Gellert Grindelwald and Albus Dumbledore. Albus Dumbledore feared to confront the truth of Ariana Dumbledore’s death and lived from guilt every day.
Aberforth Dumbledore blamed his brother Albus Dumbledore and had an uncomfortable relationship with his brother although they did keep in touch.
Albus Dumbledore relationship with Ariana Dumbledore and Gellert Grindelwald
Albus Dumbledore was initially not fond of Ariana Dumbledore because she was involved in the death of his mother Kendra, and the imprisonment of his father Percival in Azkaban.
Albus Dumbledore had to take responsibility as the eldest son but he thought it was unfair and dragging him from his road to glory.
Then Albus Dumbledore befriended Gellert Grindelwald who visited his great aunt Bathilda Bagshot. Albus Dumbledore and Gellert Grindelwald both recognized each other and had great ambitions to triumph on the world.
Later on, it was revealed that Albus Dumbledore and Gellert Grindelwald actually loved each other. Aberforth Dumbledore was unpleasant of Gellert Grindelwald as he thought Grindelwald was urging Albus Dumbledore. This got up to a fight between the three.

Albus Dumbledore’s lifelong guilt and fear of Ariana Dumbledore
Albus Dumbledore always feared to know the truth of his sister Ariana Dumbledore. He was always afraid that he might have been the one who struck the spell at Ariana Dumbledore.
The boggart of Albus Dumbledore was Ariana Dumbledore’s corpse and he saw Ariana Dumbledore and him making up with Aberforth Dumbledore in the Mirror of Erised.
Also, Albus Dumbledore was extremely alert on dementors because he feared that if his positive emotions were sucked by a dementor that he might collapse by seeing dead Ariana Dumbledore.
While drinking the Drink of Despair in the Cave Island for the horcrux Slytherin’s Locket, Albus Dumbledore was in immense pain as he saw visions of dead Ariana Dumbledore.
Albus Dumbledore has regretted his actions with Ariana Dumbledore his whole life and does one more mistake because of his guilt.
Aberforth Dumbledore
Aberforth Dumbledore was the owner of the Hog’s Head Inn and the younger brother of Albus Dumbledore. Aberforth Dumbledore was bit rash compared with his brother Albus Dumbledore but he never gave up on Ariana Dumbledore and almost even quit Hogwarts school because to take care of her which Albus Dumbledore refused.

Although Albus Dumbledore and Aberforth Dumbledore did come and forth, Aberforth Dumbledore never forgave Albus Dumbledore while Albus Dumbledore felt guilt and feared the truth of Ariana’s death for his whole life.
