The following day has class as usual, their fears of Argent discovery not having caused anything unexpected overnight.
"Right, you didn't notice I was hitting on you when I literally told you I was. I don't know, I just had a feeling."
"I'm not sure what to do with this information. Do I say something?"
"I'm not sure. I might be wrong. And besides, you're dating me and as far as she knows - and I know - we're monogamous."
"...yeah. This is that talk you wanted to have. Want to cut class? Very romantic."
"- what are the actual consequences of cutting class, here?"
"Probably we get written up. As long as you don't skip Mr. Harris you're fine."
"Eh, sure, why not."
So Stiles suggests they head to a nice spot behind the bleachers to talk.
Sure! Off they go.
"Okay, so, how does this work? Do you have a girlfriend, do we have barbecues together? Does she have a boyfriend who goes camping with us? Do I kiss boys?"
"Okay so there's a separate point here which is that watching you kiss other people would be extremely hot. That said, I don't actually feel jealousy but don't otherwise have a very compelling desire for nonmonogamy that goes beyond 'more experiences and opportunities for the both of us to be happy.'
"So the first hurdle is, are you comfortable with that? It's okay if you're not, I can drop the subject."
"I'm pretty sure I'm the opposite of immune to jealousy but I'm also pretty sure I can do it if you want to. It would be kind of hot to watch you kiss other people. That's where I am."
"Hmm. Wanna give it a shot?"
"Maybe a trial run? Or would that be worse than saying no?"
"Well, the problem with a trial run is that it would likely be limited to, like, only casual stuff."
"...yeah. Okay. I think I can handle it, let's do it."
So she grabs his face and kisses him.
He picked a good place to talk, then!
He flails his arms around before realizing he can also hold her!
Yes, that he can.
"Hopefully I can get you out of this jealousy habit."
"You're pretty convincing."
"Aren't I just," she says, and now's back to kissing.
There's some giggling and-
"Oh, sorry, is this spot taken?"
She pulls back, grinning, and looks Lydia and Jackson up assessingly - her mind was just there - then says, "It is presently occupied but I'm not opposed to company."
