"Ya know, Evans," James said casually, putting his arm around Lily's shoulders, "theoretically, if I got down on one knee, what would be your reaction?"

Lily froze, but only for a second. Her eyebrows raised. "Theoretically?"

"Yes."

"Well," she mused, leaning into James' side, "theoretically I'd give you a weird look, since I'm fairly sure I don't have a dick."

James looked at her blankly. "Wha - "

"Ask Remus to explain. Or Sirius."

"I..." He cleared his throat. "Okay, then. So, say I took you hands and started telling you how much I love you? Theoretically, of course."

"I'd probably laugh at you."

"Ouch."

"Sorry not sorry."

He huffed. "Well, say I pulled out a little box?"

"Theoretically, it could be a bomb."

He looked at her, straight-faced. She grinned back. "Continue?"

"Yes, erm..." James looked at the floor. "Well, just - say I... asked you to marry... me?"

Lily swallowed. "Theoretically?"

"Theoretically."

"Well, I'd theoretically say yes."

His eyes shone. "Really?"

A smile pulled at her lips. "Really."

He sighed in relief, fingers fiddling with the little box in his pocket.

"Of course, this is all just theoretical... right?" Lily asked, looking to the side.

"Yes, of course. Completely theoretical."

"Yes. Completely."

"Unless..."

"Unless...?"

He got down on one knee.
