"You know what they’re looking for, right? It’s called frontotemporal dementia. Areas of your brain start to shrink. It’s what my mother had. It’s the only form of dementia that can hit teenagers. And there’s no cure."
Sterek - possessive kink.
Stiles can’t quite believe what’s happening. Werewolves, he’s fine with. Werewolf rules and obligations, their social hierarchy and rankings, whatever, he can deal. But this? This is something completely foreign to him, and he has no idea how to handle it. Not when someone else is hugging Derek, his Derek, like they mean something to each other.
Crossing the road without looking where he’s going almost gets Stiles run over, but the blaring sound of a car horn has Derek and whoever-the-hell-this is looking over. Derek’s eyes widen in fear, and he starts forward to meet him as Stiles comes to the edge of the footpath, Derek pulling him off the road abruptly.
"What the hell were you thinking, Stiles? You almost got run over by a van!"
Stiles is too annoyed to answer, to say he wasn’t thinking, and he probably isn’t thinking now either, because what comes out of his mouth isn’t the smartest thing he’s said in a long time.
"What the hell are you thinking, climbing all over that … that jerk?!”
Derek frowns in confusion, eyebrows scrunched together. Then he looks over his shoulder and realisation settles over his face and he smirks at Stiles, arms crossed over his chest.
"You’re jealous? Of Howard?”
Howard. The name rings a bell… Howard, human brother-in-law to someone from Cora’s pack, an old friend that had absolutely no designs on Derek at all.
Jesus, they’d even talked about him coming to Beacon Hills last week! Well. This is embarrassing. Stiles wants the ground to open up and swallow him whole. Then he rethinks that, because Beacon Hills is fast becoming the real-life equivalent of Sunnydale and that might actually happen.
