"I don't want Mommy and Daddy to get divorced!" Lily yelled at her brother, stamping her foot. "We're supposed to be a family!"
"Lils…" Before he said anything, James grabbed his little sister in a tight hug. "You know that they'll always love you right? Regardless of if they're together or not, you'll always be their baby girl," he murmured into her hair.
At that, Lily broke into tears. "But-But-they're supposed to always love each other!" she wailed loudly. "If-If they stop loving each other, maybe they'll stop loving me too!"
Listening to his sister cry broke James' heart. He would have done anything to make it all okay for her, but he knew he couldn't sacrifice his parents' happiness for Lily's. so he'd just have to make her see the truth.
"Hey hey hey Lily," he whispered, bending down to look into her eyes. "Who said they don't love each other anymore?"
"Why else would they get divorced?" Lily asked, hiccupping.
"You love me, right?" James asked her, changing track abruptly.
"Uh-huh," Lily replied, looking confused at James' question.
"But you don't want to marry me, do you? You love me like a sibling. That's how mom and dad love each other – like brother and sister, not husband and wife."
"Ohhh," Lily said, a look of understanding appearing on her face. "But then why did they get married?"
"Because they didn't know how they loved each other, Lils. They thought it was like a husband and wide, even though it wasn't."
"Mommy? Daddy?"
At the sound of Lily's voice, Harry and Ginny's heads snapped up from where they were bent in deep discussion with each other.
"Lily, if you don't wan-"Ginny began.
"It's okay, Mommy," Lily said, running to her mother and hugging her tightly. "I know that you and Daddy will always love me even if you get a divorce. I don't mind anymore."
Ginny sent James a grateful look over Lily's head. "I'll always love you, baby," she said, holding her daughter tight. "Always."
