"I thought you went home."

JJ turned around, smiling at Reid as he joined her on the roof. "It's a nice night out," she said, shrugging her shoulders. "Wasn't quite ready to go back inside."

He moved closer, hands in his pockets. She marveled at how much he had grown up since she had first met him, how much older the new hair cut made him look. They had all changed so much in the past few years...it was a wonder she didn't notice it more often.

"Aren't Will and Henry waiting for you?"

JJ shook her head. "No."

He didn't know what to make of that, and she didn't want to explain. Finally coming up to stand beside her, they both stared out over the city.

"I love when you can see the stars," she murmured. "You usually can't in the city, but this..." She shook her head. "Tonight it's clear enough."

Reid just nodded, and she glanced over at him, nudging him slightly with her elbow. "No statistics on cities and the pollution they cause?"

He returned her smile, shrugging. "I never feel the need to give statistics with you, JJ."

Nodding, she slipped her arm through his and rested her head on his shoulder. "I'm glad, Spence," she whispered.
