DISCLAIMER: I do not own Harry Potter.
It was forbidden. He vowed to never. So why did he? Yes, he was a 7th year Slytherin, but he knew he should never! If anything - anything - went wrong, his plan would be ruined. His future would be drastically changed. The Wizarding World would know something more than he had planned. His personal life would change even more so.
He would be graduating from Hogwarts School of Witchcraft and Wizardry in just over 7 months. He would never be able to know the threat that would arise before it came. His life would be very nearly ruined, if this came to be. If there was a slight chance of this not happening, he wished very much that the 'slight chance' happened to go into effect.
But he would have a better chance of preventing this if he talked to Albus Dumbledore.
But, he reminded himself, Dumbledore was an old fool. Accepted every last creature that walked into this school with wide arms and a big smile. He never saw the darkness in any of his students. Or the teachers. Not even himself. Dumbledore's foolishness was his advantage, though. This let him get away with starting his plan earlier than anticipated.
This new threat would ruin his chances. But there was one other way to prevent this threat from becoming dangerous. And the threat would be made more... helpful. It would take a lot less energy if it didn't come.
But it did. The fateful news came two months later.
Tom Marvolo Riddle was going to have a daughter.
