Unrequited Petunina/James
She didn't hate Lily because she was a Witch she hated her because James chose her.
James had always wanted Lily and her the less pretty sister was someone he used one summer to make Lily jealous.
She had meant nothing to him, but he had meant everything to her.
Because for the first time she had genuinely believed that someone preferred her over her pretty perfect sister.
But it was all a cruel lie and she blamed Lily and Lily wasn't there to blame anymore she blamed her son.
The son that looked like the man she loved and the eyes of the women she hated.
