That gets the two of them strange looks from the other students present.

"Hello! Fancy seeing you here."

He giggles. "English was good! Anna-Sophia explained that you don't have a password! I feel like that's a really easily hackable system. Like, it's hard to guess that that's the setup, but guessing that that's the setup and being really good at bluffing are all the work that needs to be done."

"It's not really a system, I'd never done it before."

"Well, yes, but the fact that you could do it represents a security vulnerability in your friendship. Not that most people optimize their friendships for airtight security protocols, I'm just saying."

"I promise if I ever have reason to believe someone wants to infiltrate our friendship I'll tighten the OpSec."

"Good! I'm sure the members of your secret spy ring will thank you!"

"Anna-Sophia probably wouldn't actually be in my counterfactual spy ring; she'd find it stressful."

"That's just what I'd expect you to say if she was a key member of your secret spy ring!"

"If she was a key member of my secret spy ring, why would you believe her when she said we don't have a password?"

He laughs. "You got me there."

She giggles. "And that is why I counterfactually have a secret spy ring and you don't."

"The reason I don't have a secret spy ring is because I don't want one."

"True, it was your brother who suggested you join mine, not you, wasn't it."

"Lucky is constantly searching for ways to keep me occupied because if he doesn't find enough of them I fill the gaps myself and his life ends up more exciting than he prefers."

She snorts. "And he's willing to predict that we'll elope to Vegas and shoot someone but not that being a part of my secret spy ring would end up being the troublesome kind of occupying?"

"Being a part of your secret spy ring would totally keep me out of trouble."

"Maybe I should create one, then."

"Sounds like fun."

"...The secret part would be a challenge, though," she adds, glancing around the room at the relatively large number of eavesdropping classmates.

"Pff."

She winks.

"But not," she murmurs, just loud enough for him to hear, but not loud enough for the eavesdroppers, "a prohibitive one."

"Marry me."

She grins at him.

At this point the teacher comes in and would like the students to focus on calculus, please.

Calculus is fun!

It is! And after calculus Edie has French and Merry has Not French, but the block after that they apparently have Phys Ed. together.
