Just an idea! I don't know if I will continue.

Haven Peverell hated Lily Evans with all the magic in her body. People would ask why she hated Evans and Haven would say the same thing every time "She's a disgrace to all muggleborns everywhere." When Haven would say that people would always think that she was a muggleborn hater, but its quite the opposite. Haven believed that muggleborns were descendants of squibs and should learn their ways but Haven also believed that they shouldn't spit on their beliefs. The way Evans disregards their manners it's like another x on Havens list of not liker her. Haven was a Peverell and she was proud to have her ancestry and their ways. Haven was a proud Slytherin and was the princess of the Slytherin house, her house bows down to her for they are afraid of her ladyship.
