'Dear Diary,
I was taken outside today. I love the wind, and the smell of the plants. I love the outdoors. I wish Albus was with me.
Ariana'
Aberforth looked at the diary entry sadly. It was from when she was thirteen; only a year until she had killed their mother over the same book. Aberforth re-read the very first entry of the diary, and ran his wand over the page.
He saw the words transform before him, changing the simple sentences to Ariana's deepest most secret thoughts. Aberforth smiled remembering how Ariana always wrote to the right of the page...
'Dear Diary,
I love my brother! Aberforth, thank you so much for teaching me this spell! Now I can write down everything I can't tell mom...
So today, I was taken outside. Finally. It had been weeks since I last sneaked out, and that time I was almost caught, by Albus.
I can't believe my own brother, my own brother, might sell me out. I would think he would be happy that I was a normal kid; not the worst-than-dead disaster-waiting-to-happen! Aberforth totally understands, he's practically living in Albus' shadow at school.
I swear, Aberforth is the only person I can trust! He even knows what really happened when I was six.
Obviously, I don't remember entirely what happened, but I do remember that some boys came up to me and asked how I was doing magic. I said I was a witch, but something happened. Aberforth tells me it was because of the Statue of Secrecy; there was this huge bang, and my magic imploded. It hurt like hell, I definitely remember that.
After that my magic was really sporadic. My family thought it was magic at random, but Aberforth noticed that it was really just power being specifically focused.
He told mom, and she got scared, so she kinda denied me, but she still took care of me; she knew I was powerful, and she tried to hide it. Dad was convinced that the boys had caused my random magic, so he went after them, and...Well, we know what happened next.
Aberforth then became my closest friend, since he knew the truth. And Albus; he didn't care about me; all he cared about was that he could live down the shame of our father. Sometimes I wonder what it would've been like if he had just listened...
Ariana'
Aberforth looked at the diary sadly, remembering his sister. He had found it in the old house, right where she had hid it before her... passing.
Ariana was a brilliant witch. She had managed to enchant everyone--- including him--- to believe she was an unstable; a hazard. She even made Aberforth believe her magic was 'broken', and thus giving Harry Potter the wrong information, all those many years ago.
Ariana had treasured her diary, and even killed the apprehensive mother who cared little of her, over it. She convinced everyone that it was accidental, but Aberforth now knew the truth thanks to the diary.
But despite all the magic she had, she still died that night.
"I'm sorry," Aberforth whispered.
He was the one who cast the killing curse.
