"No, well-- the night before. The night before, I could tell, but before that--" he shook his head. "I didn't know. And you could have been a beta. Could have been an alpha." IF he had been, they would spend hours on one another's knots, maybe found a surrogate to have children, but Stiles wasn't. He'd presented as an omega, and he'd be the one having their kids. "I think you would have, eventually. But -- you've got instincts too. They led you to where you felt safest." To him, even though Stiles hadn't known what they were to one another yet.
It was only a few days ago, yet their friendship stretched in the months before that. And maybe he should have known weeks ago, maybe if his family was still alive, they would have known, and smiled, and smirked every damn time Stiles came over because they knew.
But it hadn't happened that way, and Derek didn't regret the way it did.
He noticed that little flush, the alteration to Stiles' scent and grinned. "No, no, I'm not down on one knee and I think, I think I'd like to be." He blinked and finally ate his bite of food. "Maybe more declaring my intentions to ask you. It's important to you-- I can tell it is. And I don't-- don't want to be one of those alphas that doesn't give you what you want. Especially when I can. When I'd be happy to. When it's something I want too." He brought Stiles hand up to kiss again, only his lips paused on the knuckle of his ring finger for a moment.
It reminded him of something else Stiles had said a few days ago, and he squeezed the fingers in his grasp before lowering them back down to the table. "We are a team. The only reason I'd ever let you go is because you asked me to." Because Stiles wasn't Kate, he'd never hurt their family. He'd never betray Derek the way she had. "I trust you. You're my mate and you always will be." He inhaled sharp and leaned forward, craving more contact and pressing the tip of his nose gently into his throat.
"I'm glad it's you. I don't regret this -- I don't regret that it's you. I never will." His eyes drifted closed as he inhaled, his mate's scent flooding his senses. "I'm gonna marry you, Mieczyslaw Stilinski."
