AN: I've had quite a few reviews commenting on the lack of other children. I never said Alex didn't have siblings, I just didn't mention them. I always intended on him having other siblings. A few days ago (at work as normal by now), Emma came storming into my head, demanding to be introduced to the world. And so, here are the Potter siblings.

Alex stood on the platform with his wife, his baby daughter cradled in his arms. They and his parents were waiting for the arrival of the Hogwarts Express bearing students home for the summer holidays. Specifically they were waiting for the arrival of Emma and Remus Potter, Alex's two siblings.

Emma Rose was the older one at nearly seventeen. She had just finished her sixth year at Hogwarts. Remus James had just turned fifteen nearly a month ago, at the end of his fourth year. Alex missed both of them while they were at school and knew his parents did too. The sharp whistle of the train drew him from his thoughts and to the scarlet steam engine pulling up to the platform. It didn't take long for the students to begin unloading and it wasn't hard to spot the Potter siblings.

Emma was first, her long, curly black hair bouncing down her back. Her brown eyes swept the crowd looking for her family. They lit up when she spotted them. She paused only long enough to gather her trunk and to make sure her brother was with her before setting off determinedly towards them. Remus hurried to keep up with his sister's longer strides. He shoved dark brown hair out from in front of his green eyes as he dragged his trunk along. When they reached them, Emma dropped her trunk unceremoniously and hugged her parents briefly before standing before Alex.

"Hello brother dear," she said cheerfully as she stretched on her toes to kiss his cheek. Brown eyes peered down at the bundle in his arms.

He laughed lightly. "Hello sister dear. Remus," he called. Their brother turned from their parents to stand by him. "I want you both to meet Lily, your niece." Blue eyes flickered open and watched the newcomers. One tiny hand raised up to grasp the finger Emma was waving over her.

"Hello little one. I'm your Aunt Emma."

Remus looked at her as he might one of his potions. "She's so little."

Harry laughed this time. "Of course she is. She's only a few weeks old."

The teen shrugged and offered his finger beside Emma's. "I'm your Uncle Remus." She latched on to his finger with her other hand. "I'm going to teach you all sorts of pranks when you get older."

Alex just shook his head and smiled. Remus took after at least one of his namesakes with his love of pranks. "No pranks until she's many years older, Remus. She's too little now."

Remus rolled his eyes at his brother. "I know that. But one day…"

The older girl shook her head, curls falling over her shoulder. "She'll be smart too. And like reading."

"She'll be well loved, that's for sure," Hermione said, though she was shaking her head at her two youngest. "It's time we're getting home. I'm sure Lily will need feeding soon."

"And me!" Remus proclaimed.

The adults laughed. "Like I could ever forget that," she said.

"Could I… could I hold her later, Alex?" Emma asked quietly as she followed him to the floo point.

He smiled at his sister. "Of course. Maybe this summer, if you, Mum, and Dad are okay with it, you can watch her for a few hours so Maria and I can have some quiet at our house."

"Really?!"

"Of course." He leaned down the slight distance to kiss her forehead. "I'll be right behind you." He watched as she disappeared through the fire, a look of excitement still on her face at the prospect of babysitting her niece.

"Does she know what she's getting into?" his wife asked softly beside him.

"Probably not, but if it gives us some quiet, that's fine. Mum and Dad can help her if she needs it. And we," Alex said, giving her a brief kiss, "can maybe eventually try giving Lily a sibling."

Maria laughed. "Maybe in a year or so." She skipped ahead and through the fire after Hermione.

The only ones left were Alex and Harry. "Everything okay?" Harry asked.

A smile grew on Alex's face. "Just perfect. Everything is perfect."
