She plants a kiss on Stiles' lips and then they have Destinations to go to, apparently.

As expected, Ade has chemistry. 

Her Chemistry Friend doesn't seem to recognize her. 

She recognizes him. "Hello! What a beautiful day for chemistry, isn't it?"

"Isn't every day? I'm Matt. Are you new?" 

"Well yes, I am. Got here two days ago."

"Oh. That's some really good makeup game. Any tips?"

"None that I can really give you over chemistry, but if you like I can teach you a thing or two later."

"On second thought, I'll keep my sense of wonder. Ready to get started?" 

"Yep."

They proceed to be very educated about pH indicators, through a helpful experiment. 

Yay! pH indicators!

Look at that, the teacher is hovering over her shoulder. 

"Someone who actually seems to have a basic grasp of the material. Congratulations, Mr. Daehler, you lucked out with this one. Everyone should be moving on to their lab reports by now, because if not, I won't have anything to grade in ten minutes, and my only hobby is failing you. Mr. Iroko, please see me after class." 

"It's Ms. Iroko today," she corrects, moving on to writing her report.

"Are you on the lacrosse team?"

"Yeah!"

"Mention it to him when he talks to you, he's easier on athletes." 

"...should I be worried? As far as I know I have not yet done anything that should merit special teacher attention."

"He's impressed but he hates everyone, so he's trying to test you."

"So why's he easier on athletes?"

"I don't make a habit of actually getting to know my teachers, just find a way to work with them. Sorry."

They finish up their lab report, and turn it in. There are a few stragglers, but class is winding down.

And she stays behind to talk to the teacher.

He shifts some papers around on his desk, placing them in a drawer.

The desk is meticulously organized, and sparsely decorated. The only personal item is a plaque that reads: A cadet will not lie, cheat, steal, or tolerate those who do.

"Ms. Iroko, sit down. Any seat is fine. I'll give you a note for whatever class you have next."  

"Okay." She sits.

"Usually when a student's name is wrong on my class roster, it's administrative incompetence, but it looks to me like your name was spelled just fine, and it also looks to me like every official document I can access without actually talking to someone can't decide if you're a boy or a girl. Are you going to be announcing which one you are each day, or should I just rely on the, the visual cues." 

"You can also ask, I won't be offended. It varies day by day."
