Holly.

'My parents are alive. I have a baby sister… My parents are wizards, and so am I and so is she, and my - our - parents are seen as magical terrorists.'

Harry was holding the crying baby girl in his arms, scarcely able to believe that the little girl was his baby sister. He was trying, and failing, to stop her from crying. She had appeared on the doorstep as he had, only instead of being found the moment the front door was opened, there was a knock on the doors as the Dursleys and Harry had been eating dinner.

And from there, Harry's entire world had been turned upside down.

"Shh, please, it's okay," Harry whispered to the little girl, but right now all of the plans he had prepared for over the months seemed to have been thrown out of the window.

For years the Dursleys had told him his parents hadn't wanted him, that they were criminals, layabouts, and whores. They had never failed to remind him that he had no family. They were relatives, completely different. They had told him he was unnecessary and unwanted.

But reading that letter, hurriedly written by his mother, Harry knew the Dursleys were wrong. He and Holly were wanted, but they couldn't look after her as it would endanger them all and while the letter was brief, it was enough to convince him they were telling the truth. Harry had never really given his parents much thought.

The Dursleys' lies had seen to that; at first, he had been sad and horrified by their lies before he'd realised they were lying, and he had just been forced to accept that over the years. Later he had decided to just care about the now, where such things didn't really matter that much to him anymore.

But now everything had been thrown out of all proportion. Now he knew that magic existed - the magical photograph enclosed in the letter, the same photograph Vernon had tried to destroy, showing a loving couple holding little Holly with a scribbled note on the back saying how much she was loved and how much they loved Harry, with their smiles tinged with sadness as if the photograph copies of Lily and James Potter knew they would have to leave her in Britain, Harry was more worried about the future.

The Potters' letter with Holly had made it clear they had been on the run following a war they'd been fighting in before Harry was even born and they had been accused of being terrorists, the servants of the Dark Wizard terrorising the country at the time. While they hadn't expected Lily to become pregnant with Holly, they'd known they couldn't leave her in some orphanage somewhere, with no hope of knowing who she was, and where she came from.

They had risked their lives and their freedom bringing her to the Dursleys, and then they'd been forced to leave as quickly as they could. There was no mention of where they were, or where they'd be going. Harry was saddened by that, but he understood.

Harry felt a small hand on his cheek, and he looked up. The little girl, the precious little girl was patting his cheek, gurgling. Harry thought his heart would shatter into little bits when she snuggled into him, to find warmth and to share her own. Harry cradled her gently, and he brought her closer to him.

"I will look after you for the rest of my life," he vowed.

Harry gently put her down, eliciting a surprised gurgle and sob from the baby, but he ignored her for the time being. He had no intention of staying here, and he definitely had no intention of leaving Holly here. Harry knew he could have stayed for a bit longer, and delayed his plans, but he decided now was the time to leave.

After grabbing his stuff, Harry picked Holly up and opened the bedroom door after making sure she was bundled up. As he trudged down the stairs, Harry waved his hands, focusing on making the Dursleys fall asleep. Once he checked on them, and saw them snoring away, Harry smirked at how well that had worked before he opened the front door and walked out.

Walking through Little Whinging, Harry was ignored thanks to his magic. He had no idea where he and his little sister would go from here, but they would never come back. In the open air, it was easy enough for him to make a plan. The Potters had made it clear they'd found him through a ritual, and since they'd left Holly behind with him since they believed she should be with her brother, that meant they could have other kids. He would need to keep watch on the Dursley's house.

But right now he had other things to worry himself with; he had to take Holly into London. He would need to find a place for them to stay and he'd have to learn how to look after a baby and fend for them both, but Harry Potter was good at learning and surviving.

The Potters had made it clear to him in their letter that he and Holly would be attending their old magical school when they were both 11 years old respectively, and Harry planned to be ready for that day.
