The Diary Tom Riddle, now reduced to a tiny ghost, flew up to the sleeping Tom Riddle, and went inside his head. Albus Severus struggled, clutching his forehead. Finally, Tom managed to subdue him.
Albus woke up and talked in Tom's voice, "This will only work for five hours when he is asleep, three hours when he's awake. I'm not strong enough for longer."
The eldest Voldemort said, "That's enough. Make sure the image given is perfectly realistic. He must believe that he is being mocked, and then locket Voldemort will act perfectly sweet to him, while slowly enchanting him to make the potion. Do you understand?" "YES!"
The next morning, Albus went to class when he was asked a question by Professor Binns. "What was the first wizard to discover wandlore?" "Um, was it Alve Sona?"
"WRONG AGAIN MR.POTTER! Just like your father. Both of you are good for nothing! But at least he saved us! You are disgracing him!" Professor Binns shouted.
The Slytherins and Gryffindors both jeered at Albus, leaving him in tears. He ran up to his dorm and went to bed, skiving of his classes and cried away. The next morning he woke up, with people laughing at him.
Rose saw him in the Great Hall. "Albus what is wrong with you? First during the whole of History of Magic you had a glazed look on your face and then ran out crying to your dorm and we didn't see you since!"
Albus was puzzled. He just remembered that Rose was laughing at him and he knew she would never do something like that. He pondered over it with the Voldemorts watched in fear. When Tom fully recovered he went back inside Albus's mind, and erased the memory of his meeting with Rose and placed more bad memories into his mind. Next week, Locket Voldemort, then went up to Albus's dorm. He saw him crying over another false incident. He said, "Hey, little boy, don't cry. I know what you're going through. I went through it at your age, dear boy."
"Huh?" That piqued Albus's interest. Over the weeks, Albus got closer and closer to the cute little ghost.
One day, Locket Voldemort told him, "I've helped you so much over these past few weeks. I was wondering if you could do a small favour for me. It's really simple actually. All you've got to do is make a potion. First, put ¾ water, and then add boomslang skin, one drop of Runespoor blood, skin of a Puffskein, and finally eye of a Demiguise. Stir counter-clockwise three times and leave it there for one night. The next morning it will be gone."
He began to disagree, so Diary Tom possessed him. "Yes! I shall make the potion!"
So he began, stealing items from the Potions cabinet, dodging Professor Patil, working feverishly day and night, preparing the potion and ingredients, as the Voldemorts took turns possessing him.
When the potion was ready, the diadem Voldemort flew out of Albus's body, who promptly fainted, and dipped himself into the potion. A whooshing sound was heard and he vanished. The other horcrux Voldemorts dipped them in the potion. Slowly, Voldemort became full.
"Yes! Finally I am one! Harry Potter defeated me once, but then I was only 1/8 of myself! Now, with all of my horcruxes and me combined and his security lax, I shall defeat him. But first, the boy must unite all three deathly hallows, so that I can rule forever immortal! Wahahaha!"
