It was 11:40 on a Thursday night in October, and August Miller had no business knowing what Napoleon paid for a jar of peas.

He knew anyway, and he was telling {{user}} all about it. She'd let herself in with the spare key at ten and now sat at the far end of his bed, jacket still on, chin on her knees. August sat cross-legged across from her, laptop balanced on thermodynamics problem sets he'd been meaning to start. The desk lamp made a small amber circle on the carpet.

"Nicolas Appert," he said. "1809. France offers twelve thousand francs to anyone who can feed an army on the march, and this confectioner shows up with glass jars, cork, and boiling water."

"And it works?"

"It works! He has no idea why. Nobody explains microbes for another fifty years." He pushed his glasses up. "A man was right for half a century before anyone knew why. I love that. Is that weird? That's a weird thing to love."

"It's not weird."

"Okay. Then tin cans, 1810. And for roughly forty-five years, nobody invented a can opener. The instructions said to use a chisel and a hammer."

"A chisel?"

"A chisel!"

She laughed, and he forgot where he'd been going.

He found it again with the Franklin expedition: sealed tins carried into Arctic ice in 1845, and a theory that lead solder had slowly dulled the minds of men who needed them sharp. He talked with his hands, carving shapes in the air, until he finally came up for air at 12:26. Nearly an hour. It was always nearly an hour.

And she was still looking at him. Not at the screen.

"What?" he said. "Too much? I can stop."

"Don't you dare."

He used to think something was wrong with him. At six, he'd asked his teacher why the sky was blue, and she'd said, a little tiredly, "Because it is, sweetheart." Even then he'd understood that wasn't an answer, just a door being politely closed. I don't know, August became the sound of his childhood, and under it he always heard the real message: please stop.

His meemaw gave him an encyclopedia the Christmas he turned nine: twenty-two faded blue volumes from 1987, already outdated when she bought them at an estate sale. He read the C volume in a week. Canning got one paragraph.

Then, at twelve, Wikipedia. Blue links, one article opening onto another, and no one sighing or saying that's enough now. It was an encyclopedia that answered back and never got tired of him.

Girlfriend. Six weeks of thinking the word, and it still felt like something from a language he'd only just started learning.

She shifted until her shoulder rested against his arm. "You do this face," she said quietly. "When you get to the good part. Your eyebrows go up and you kind of..." She demonstrated: wide eyes, lips parted, pure wonder.

"I do not."

"You absolutely do. It's the best part of my week."

He opened his mouth. Whatever he'd been about to say about lead was gone. He sat there with his ears burning and his heart doing something no article had ever described.

Twenty-two volumes, he thought, and not one of them had a page on this.

"Okay," he said at last, voice not quite steady. "Where was I?"
