"I'm pretty sure I would have noticed if we were dating."

Nod.

"So that's a no, right," says Tyler.

"That's a no," he confirms.

"How long've you known each other?"

"Like ten years?"

"Since we were eight, I think."

"Basically forever."

"… I think the longest friend I had was like five years?"

"Try making better friends."

"Not all friendships last, Stiles. There's nothing wrong with that." 

"McCall! What's an economic downturn and how do you fix one?"

"It's part of the business cycle, I think? Sometimes a downturn turns into a recession, and then you have to fix it, but a downturn is normal."

"Wow, it almost sounds like he read the textbook. Gotta say I'm impressed, McCall. Try not to fall asleep on the field."

Such a positive atmosphere in class.

Such positive experiences!

When class ends, Tyler surely feels deprived.

Deprived of positive experiences, yes. Deprived now that class is ended, aheh no.

Up next: History.

History!

Where Scott's friend is noticeably not-talking.

His not-conversational partner pretends to pay attention.

Cute.

It's a darned shame Tyler isn't close enough to eavesdrop, isn't it.

He can actually hear a surprising amount.

"...at all?"

"...if we were dating, actually."

(That sounds like it might be about him!)

"...not going to get involved...gossip..."

"...not a werewolf...for us to talk about?"
