Thousands of years ago, Rolf went to the Albanian forest to collect Helena's body, and accidentally witnessed the death of Ravenclaw.
There is no doubt that Helena was killed by Barrow, but there is no solid evidence whether her mother Ravenclaw was killed by Slytherin.
At least when Rove arrived at the scene of the crime, he only saw Ravenclaw's body and not the murderer.
Thousands of years later, Grindelwald retrieved the memory through the soul in the basilisk's body, and finally confirmed that the murderer... was Salazar Slytherin!
Slytherin, one of the Big Four, killed Ravenclaw. This sounds like a very psychedelic thing, but there is also a sufficient motive.
Hufflepuff once speculated that Slytherin might be trying to get the 'sealed left arm' to complement the ancient wizard's body.
But Rolf never expected that Slytherin would make a Horcrux while killing Ravenclaw!
And the existence of Horcruxes is enough to show that Slytherin himself is still alive... This is extremely bad news.
"When I was extracting memories, I also discovered something interesting."
Grindelwald stretched out a withered and spotted hand, gently stroked the skull pipe and said:
"After Slytherin killed Ravenclaw, he quietly returned to Hogwarts, let the basilisk enter the Chamber of Secrets, and began a long sleep."
"After that, in nearly a thousand years, the Basilisk was awakened three times and met three wizards."
"Corvinus Gunter, Tom Riddle and..." Rolf stretched out a finger, pointed at himself and said: "Me."
"That's right." Grindelwald nodded and said:
"Corvinus Gaunt has spent the longest time with the basilisk, and he even left Hogwarts with it..."
Dumbledore turned his attention to Grindelwald and frowned: "Where did they go?"
Hearing Dumbledore's words, Grindelwald seemed to have a great sense of accomplishment and satisfaction, and deliberately said in a nonchalant manner:
"you guess?"
"You like to talk or not."
"Then I won't say anything."
"..."
For a moment, Luo Fe felt that standing in this room was a superfluous existence. He wished he could leave immediately and leave the world for the two of them.
The two of them struggled for a long time before Grindelwald slowly said:
"They went to Ilvermorny School of Witchcraft and Wizardry."
"Ilvermorny?" Rolf was surprised when he heard the name, "What is Gaunt doing there with the basilisk?"
"I don't know." Grindelwald shook his head. "The basilisk is entangled with Slytherin's soul. The memory is very fragmented. I can't extract any effective information."
Dumbledore was thoughtful.
Grindelwald did not interrupt his thoughts, but stared at Rolf intently.
"Boy, I also noticed one thing. Gaunt and Riddle both followed the Basilisk... or in other words, under the bewitchment of the Horcrux, they learned the black magic left by Slytherin.
Especially Tom Riddle, when he was sixteen years old, he asked a basilisk to kill a female student and make a Horcrux."
Grindelwald paused, caressing his sleeves with his bony, wrinkled fingers, and then continued:
"And you... actually rejected the Basilisk and did not follow it to learn Slytherin's magic."
"Isn't it possible?" Rolf asked.
"Those are all powerful magics. Look, Voldemort has now become the best descendant after me."
Grindelwald's blue eyes were deep and cold, and he smiled:
"If you dislike Slytherin's magic, you can learn from me. I promise that you will not lose to Voldemort in the future."
Rolf held back his laughter, looked at Dumbledore and said:
"Professor, I am reporting Grindelwald to you. He has evil intentions and wants to develop me into a Umbra Party. I suggest that you transfer him to Azkaban to receive re-education as a Dementor."
"..."
Dumbledore came back from his thoughts, he smiled and said:
"Rolf, I will consider your suggestion. You can go for a walk and visit Grindelwald's prison... go ahead."
Rolf hummed, turned and left, leaving the room to Dumbledore and Grindelwald. When he went out, he also... locked the door.
Grindelwald stared at Dumbledore and smiled meaningfully.
"Why, are you afraid that I will teach him bad things and lead him astray?"
"Don't worry about that." Dumbledore said calmly:
"Rolf and I have been together for a long time, and I know this kid better than you. He still has a long way to go, but he is definitely not someone you can influence."
"Besides." The old man paused and said, "With Newt and I here, I won't let Rolf become the second you."
"Do you think so highly of him?" Grindelwald asked curiously.
"Of course, otherwise I wouldn't have brought him to see you." Dumbledore said with a smile:
"I'm not the only one who thinks highly of Rolf, Hufflepuff and Ravenclaw all do the same."
"That's just because he used the time turner to go back a thousand years ago and met them. It doesn't mean anything." Grindelwald insisted.
"Rolf can use the time turner to go back a thousand years ago and come back unscathed, which already explains a lot." Dumbledore said with a smile:
"When you and I were at his age, we were far inferior to him... He had greater goodwill towards the world than you did, and he knew what he wanted better than I did."
"Anyway, I like this kid."
Grindelwald raised his sparse eyebrows, and when his eyes met with Dumbledore's, those eyebrows softened again.
"Albus, if I had a teacher like you to guide me, everything would definitely be different.
Maybe that wrong summer would never have happened, and we wouldn’t be in this situation.”
Hearing the words "The Wrong Summer", memories came back to Dumbledore's mind quietly. Some old wounds never heal, and it only takes a few words to make them bleed again.
The old man said bitterly:
"Gellert, there is no point in dwelling on the past and regrets. Imagination belongs to an old man in his twilight years."
"But I am just an old man in his twilight years. Apart from waiting to die every day, all I have left is memories."
Grindelwald, his body hunched, stood quietly by the window, looking alone into the sky, with the cold wind whistling around him.
"I may be dying, but I have been dreaming about the past lately...especially that day, when the two of us lay on the grass and made a blood pact, swearing to never betray each other and never hurt each other.
The sun was so bright that day.”
Dumbledore fell silent.
A drizzle suddenly started falling outside the window, hitting Grindelwald's face slantingly, like tears, but he didn't seem to feel it at all, and just sighed:
"You think that day is just another ordinary day, only to find out years later that it was actually the best day of your life.
It’s just that a day like that will never happen again.”
Dumbledore remained silent, but his eyes were filled with sadness.
