The other's story
Albus Severus Potter
He hadn't been very old when he lost count of how many times people had told him how much he looked like his father. It was true, he knew, being the only of the three Potter children to have inherited his dad's green eyes the similarity between them sprang to the eyes of everybody. It still could get rather annoying, after all, when people used to say it to his father they always added the "but you have your mother's eyes." With him it was all "You look exactly like your father."
Sometimes, when he walked the corridors at Hogwarts, he was sure some of the ghosts and pictures couldn't figure whether Harry was back or what. Yes at one point he was sure the mad knight Cardogan had yelled "Harry" after him.
At the train him and Rose had found a much unexpected friend; Scorpius Malfoy, at first it had been rather awkward, here they were, two boys; both looking amazingly like their fathers who had been rivals at school but in the end they had realized that being enemies because their fathers had been was completely idiotic.
He'd told the Hat to, please, not put him in Slytherin and it had said he was just like his father before it announced his placing in Gryffindor.
He soon found out he was really good at potions; it was just so fun to see the cauldrons bubble and simmer when the ingredients were added.
At one point he'd been taken to the headmistress's office and been left to wait for a while. Not knowing what to say to the portraits of the two men he'd been named after he told Albus Dumbledore that his father had said he'd been both brilliant and a little mental, and Severus Snape that he'd been the bravest man his father knew. They both seemed really proud.
