Title: Follow You
A/N: Written for the Birthday Surprise Competition. Happy 18th Birthday Kaia (acciohope15)!

Rose had known Lorcan forever. Not just in the way people had known their best friends since nursery school: this was the literal version of always. When she was born (seventeen whole years ago, can you believe it?!), Luna had been standing by her mother rocking the two month old twins.

They had shared everything from toys to chicken pox over the years while Lysander kept mostly to himself. At age four Lorcan had somehow been dragged to Muggle primary school with her. They had screamed themselves hoarse at the idea, then returned home covered in paint every day.

Then the twins, who were about as alike as night and day, hit eight. Suddenly they were considered old enough to stay with Rose and her family when Aunty Luna and Uncle Rolf went on extended trips. She became so used to waking up and seeing Lorcan asleep in the next bed that it felt strange after he left.

They left for Hogwarts together, gripping each other's hands tight as the train sped away from London. Even among the enormous extended family in their apartment, butterflies swooped and twisted in their stomachs.

Rose stood in front of the staring students, sorting hat balanced precariously on her head. It slid over her eyes every now and then and she pushed it back into place. She glanced at the clock. Only one minute until she could be considered a hatstall – the first Weasley in living memory not to be instantly placed (mostly in Gryffindor).

"Ravenclaw!" It finally shouted, an explosion of applause greeting Rose as she stumbled off the stage and took a seat. People patted her on the back and shoulder, eager to see another war hero's child in Ravenclaw. Teddy had been sorted there, but no-one else. Which meant she was without her family for the first time ever.

She watched as Lysander was sorted into Slytherin, then crossed her fingers tight as Lorcan was called up.

"Scamander, Lorcan!" The hat seemed to have an intense conversation with him. Lorcan shook his head violently at one point, until the hat seemed to give up and announced him the newest Ravenclaw.

Rose cheered and clapped with everyone else and she smiled widely when he sat next to her. He returned her smile.

"What was the head shaking thing about?" She whispered.

"I wanted Ravenclaw," he muttered awkwardly.

They grew even closer with each year that passed. Fourth year saw them sneaking into each other's dorms to spill their deepest secrets at midnight, and a warm fuzzy feeling in Lorcan's heart when Rose hugged him. Fifth year was casual flirting, passed off as a joke. When they turned sixteen it shifted to kisses on the cheek and their first real date.

Seventh year had begun with a family feud; Albus had told her parents about the relationship. The adults had cooed over the cuteness of the pair. Rose had been furious at Albus. She didn't properly start talking to him until Christmas. Lorcan had been rather unnecessarily introduced to her parents, with her Dad making the expected death threats and Mum attempting to keep Ron under control. She had admired Lorcan even more for putting up with that.

But looking back on it all, Rose had been certain Lorcan would follow her anywhere at that sorting ceremony.
