She had been called 'the younger Evans kid', 'Lily's sister', and worst of all, 'the other girl'. The quiet one, in the corner, wearing her sister's hand-me-downs, everything but forgotten while Lily herself laughed and chatted, with a smile for everybody.
She wished she was like that.
She was dark instead of light, wistful instead of laughing. And jealous. Jealous of her sister's friends, her looks, even the extra attention her parents said they didn't pay to her.
When Lilygot her letter, was special, was magic, she supposed it was like everything else. Lily was always better.
But Lily faded out of her life, only coming in in short segments in winter and summer break, and even then, always talking to and about her friends, and later, her boyfriends.
The summer that Lily brought home James Potter was the summer that she met Vernon Dursley. She hated him. But he brought her flowers, and she made herself pretend that the greedy look in his piggy eyes was the look that James gave Lily.
Lily was always better.
She pretended she didn't care when she found out her sister was dead. She didn't know what she felt: sad, happy, jealous, thankful. She was invited to the funeral. She went, but didn't tell Vernon. There were her kind there. They didn't know her except what Lily had told them. And she was gone.
The other girl.
Lily's sister.
That wasn't her anymore.
