And when he goes to school the next day he doesn't even act hurt or anything, he won't look at Jackson at all or otherwise acknowledge his existence. Even when Jackson tries to get them alone together he just sidesteps away.
Stiles keeps glaring at him wherever he goes and suddenly his Porsche is a target for any law enforcement officer ever, parking tickets, a being pulled over twice a day (AT LEAST) become the new normal for him and Scott leaves the lacrosse team so he can't even try to talk to him after practice about anything.
Meanwhile Scott starts picking up extra hours at the vet and taking his mom dinner at night when his shifts are through. One night there's a big sad huffy looking old english sheepdog for him to care for named Jinx who has really bad tummy ache but nothing that can't be cured with a little love and some laxatives. And that's exactly what he tells her almost overwhelmingly hot owner, when he comes to pick her up.
But essentially Derek and Scott start having a fun little flirtationship that turns into a relationship (i aged derek down a bit so he's 19 going on 20 and Scott is 17 so it is underaged but not to bad as it would be legal in most states?) And they spend a lot of time together and Derek is really happy to be dating Scott so as soon as it's official he takes him to meet his family because he's so happy he wants everyone to know how awesome his boyfriend is. When he meets Mama McCall he's polite and respectful and a perfect gentleman (he brings flowers) and offers to come help out around the house if they ever need anything.
Even though Stiles is apprehensive they hit it off as well and bond over their mutual love of being snarky little shits. They toss sarcastic barbs back and forth when ever they end up left alone (Scott thinks it's good that this boyfriend is getting along with Stiles, he hated the last one)
Things are going really well for Scott and he's very happy, Jackson on the other isn't. Their team has been on a massive losing streak since the co-captain stepped down and Finstock has been riding his ass about. And Lydia keeps downtalking him about his losses and it frustrates him because he's Jackson Whittemore, he is number one, even when he's losing he's still number one, he doesn't need Lydia Martin talking down to him because his team is full of losers.
And on top of that he sees long-tan-and-fuck-him picking up Scott everyday in a goddamn Camaro (Scott always looks happy as soon as he sees him pull up to the school and he wishes that would smile like that and get into his porsche).
And between everything Jackson just starts getting jealous as shit. He barely sees Scott but he still hates this new motherfucker for taking him away (it doesn't matter that they broke up, they always break up, they were supposed to get back together two days later like usual).
I dunno I just want Scott and Derek to be cute happy little cupcakes and for Jackson to end up alone while Lydia leaves him for the cute new girl who just came to town. That's it. Jackson suffering everywhere.
