The Beginning
Harry walked into his bedroom kind of zoning out. That's how he had been for the past while. Since...since Cedric died. Once he walked into his room however he was quickly thrown out of his brain.
There was a baby, a crying baby laying in a basket on his bed, wearing nothing but a dirty diaper. The baby didn't seem very old probably a month at most though he didn't think it had had a very good life for however long it had been at the Dursely's. Harry did have a bit of experience with babies as the Dursely's had forced him to babysit when he was younger. Just so they could take the money of course, but still it did give him experience.
-1 hour later-
After Harry had fed, bathed, and changed the baby (then waited about half an hour after it fell asleep) he went down to the living room.
All three Dursely's where there as he expected so he quickly went over to confront them.
"Why was there a baby on my bed? Who's baby is it? Where are the parents? What's it's name? How old is it?" Harry asked all these question in less than a minute, not letting the other three people in the room interject until he was done.
Vernon began speaking first "The baby is on your bed because it is yours now. Some evil women seduced Dudley then once pregnant forced us to take the child. And of course the devil child end up being one of your kind, which is why you're taking it. The child" Vernon said as if the baby was no such thing "is a month old it's birthday is May 2nd according to the mother. And it doesn't have a name because it doesn't deserve one."
Harry exploded with anger, a newborn, how could they do this to a newborn. He wanted to yell and curse and give them the punishment they deserved. But, he couldn't because right above them was a baby. His baby. And he was not letting his child wake up to him screaming.
So instead Harry walked upstairs, grabbed the basket with the baby in it and his trunk before walking outside and away from his childhood 'home' for the last time.
