"And he only thinks he's good at keeping secrets." Derek knew better, but he also knew it was in Stiles' nature to try. At least his mate wasn't a quitter.
Still, all the conversation made him feel cool, like he was missing the addition of Stiles' warmth tucked into his side and he reached out, hand closing around his hip and nudging him against his body.
This close, yeah, it was all warmth and happy scents coming off the both of them and they still managed to keep their clothes on. For now, at least.
"Yeah, he smelled like them when he's come home the past couple of days." What Scott was trying to say and not trying to say -- Derek got it. Besides, Derek also knew that his pack wasn't interested in sex with Stiles, nor his mate with them. "And Stiles isn't wrong. When you take a mate, your pack is going to want to put their scents down on them as well. And you're going to want that." Of course Derek wanted Stiles to smell of him, and of them together, but he also needed to smell of pack. It was good, and right, and maybe Deaton could explain all the stuff behind it, but Derek knew that it was simply wanted.
He went a little quiet as he listened to them. Scott might not accept, but for Stiles, the invitation had to be made. "You're always welcome here, with us Scott. I know you're still figuring things out, but I'm not going to keep you from seeing one another." Stiles probably already knew that, but Scott -- he probably needed to hear that, to have that reassurance.
"I know he's your family; he's my family now too," Derek said quietly.
