Lily Luna Potter had inherited her father's invisibility cloak.
This had come as a surprise to her, as Albus was far and away Harry's favourite, but when Lily turned thirteen, Harry had given her the cloak and told her that she was the only one of his children he trusted to use it properly. James, he said, would have abused the power that came with it, and Albus wouldn't have used it at all.
Lily treasured the cloak, and only ever brought it out on rare occasions, most often occasions when she felt in desperate need of a walk around the grounds at night.
Tonight was one of these occasions.
Lily slipped out of bed, careful not to wake her dorm mates, and wrapped the cloak around herself. She tiptoed out of the dormitory, down the stairs to the common room, and stole through the castle out onto the grounds.
As soon as the castle doors closed behind her, Lily felt free, elated. She drew in a deep breath from the night air and threw off the cloak.
There was a yelp of shock from her left and she spun around.
"Jesus Christ, Potter, you gave me a heart attack!"
"I gave you a heart attack?" Lily thought she was about to pass out from sheer shock. Scorpius Malfoy was there, clutching the castle wall to stay upright, and she was met with an incredible urge to give him a smack. "What the hell are you doing out here?"
"What the hell are you doing out here?"
"Taking a walk!"
"At two in the morning?"
"Well, what are you doing?"
Scorpius hesitated, then sighed. "Taking a walk," he admitted.
"How'd you get out here without me seeing you?"
"Invisibility cloak," Lily told him, handing it over. Scorpius raised his eyebrows, then wrapped it around himself from the neck down. "Wow…" he said, eyes widening in genuine awe.
"Now give it back."
He did so, letting out a long, low whistle. "That's… impressive."
She shrugged, throwing it on the ground like a blanket and sitting down on it. "So, why were you really out here?"
"Told you, I was taking a walk."
Scorpius blew out a breath and sat down next to her, shrugging. "Looking at the stars."
Lily snorted in spite of herself. "Never figured you for the stargazer type, Malfoy."
"I guess it runs in the family. I mean, obviously my family was mad about stars or something. Why else would they name me 'Scorpius'?"
"Because they're sadistic and they hate you?"
"Thanks for that, Potter." A pause. "You know, if you weren't such a mean-spirited bitch, I might almost like you, Lily."
Lily rolled her eyes up, the stars' reflections glittering in the whites, but she smiled.
"You know, if you weren't such an arrogant prick, I might almost like you, Scorpius."
