"How..." Sirius Black looked surprised. "Lily never told me any of that."
"Harry's mother seems to have been a very well-bred lady, one who didn't go around airing her sister's private affairs." Allen shrugged, pointed at himself, and said with a grin, "But I'm different. I rather enjoy speaking ill of other people... so it looks like I'll have to tell you some things... You know I can learn a thing or two from the Ministry of Magic's intelligence files."
Allen used the Ministry of Magic as his excuse for why he knew these things. Harry first nodded, then, afraid Allen would misunderstand, quickly shook his head. He was shocked. Having spent seventeen years in that house, he knew full well how much they rejected magic.

Ever since she was little, she had many unusual abilities—for example, she could make the petals of a flower open and close in her palm without touching it. That left Petunia with very mixed feelings: jealousy, and disdain as well. And your grandparents loved praising Lily's abilities. I think that may have been one of the reasons her jealousy formed..." Allen spread his hands and praised Lily, which made the two wizards before him, one older and one younger, look rather pleased. Allen continued, "Your Potions Professor, Severus Snape, lived in Cokeworth back then, just like your grandparents. Severus had abilities similar to Lily's... After they met, Petunia and Snape looked down on each other from the very first encounter. Lily, however, was drawn to Snape, and the two of them quickly became good friends... But while the three of them were spending time together, your aunt clearly felt even more encouraged. She wouldn't admit it aloud, but it was obvious she learned more from your mother
