Voldemort stared at the parchment in front of him. It couldn't be true! It just couldn't! There had to be some mistake. Voldemort glared at the potions master in front of him.
"Crucio"
After a minute he released him and stalked out of the room. He couldn't let anyone find out, but one person already knew and he had no idea what they'd do. So he did what any person in this position would do. He wrote a letter.
A month later
The great hall was full as the leaving feast began. However, just half an hour in the doors flew open. Everyone in the hall jumped up, ready to defend themselves and their school. Stood in the doorway was a lone figure, his face hidden by a hood. He strode forward ignoring the wands pointing at him. As he reached a point along one of the tables he stopped and looked at the person in front of him on the bench.
"Harry my boy, who is this?" asked Dumbledore from across the hall.
Harry stood up and smiled at the lone figure who held out a piece of parchment to him.
FLASHBACK
He wandered along the street, trying to stay in the shadows. When he'd smashed into the time turners in the ministry he hadn't expected to go so far back in time, which was about sixty or seventy years he thought. All he could do was try to find a way back, but first he had to change these clothes and try to fit in.
It wouldn't do for him to be caught out, who knows what the ministry in this time would do. He wondered if he should go to Dumbledore, but how would he persuade him he was telling the truth? Then there was how to find him. Going to Hogwarts made sense but he'd have to get past the other teachers.
However, this plan was scrapped as a woman crashed into him knocking them both to the floor. Hearing the shouts heading their way he didn't stop to think, he pulled her up, grabbed her hand and ran. That was how he met Merope.
ENDFLASHBACK
Touching the offered piece of parchment he turned to face Dumbledore.
"My son"
And he was gone.
