Derek wasn't sure if it would be something John would want either, but he wouldn't know until the invitation was issued. He'd briefly wondered before coming here if being back in this restaurant would hurt, if it'd remind him too much of his family, but -- Talia would want him to come. His dad would want him to be here. This place was a part of their family history and he wanted to share it with Stiles -- with his mate. Maybe John would want the little place he and Claudia frequented to be a part of them too.
"I'd love to hear it," he grinned, knowing better than to believe Stiles innocent for a second. He hadn't believed it when they met years ago, and now he definitely knew better. His grin widened at the slight pulse in Stiles' scent, a sharp note of spicy that he knew meant his mate was aroused.
"Alright." His sense of taste wasn't as developed as his sense of smell was, but it was still far more acute than a baseline human's. The wine was delicious, and the only thing in the world that could make it better was to have it mixed with Stiles' taste.
The interruption forced Derek's gaze away from his mate, but he still held onto Stiles' hand as he got a little piece of the alpha's story. It was a huge difference from yesterday and walking through the police station, but that's what Derek wanted. Someplace safe, someplace they could both enjoy, where Stiles wasn't treated differently for his presentation. "Thank you," he said warmly, offering up a genuine smile to the older man. "May you have many more, long, happy years together."
He laughed a little at Stiles calling out to them. They were a handsome couple, and would likely have decades more together, but there was something in the fondness of their eyes that spoke of a long life already spent together, and something warm curled up in his middle and settled there, happy.
One day that would be them. One day they might be watching kids, maybe their own kids on their first date with their mates. It was common for mates to be young if they were close prior to presentation; if they didn't know each other previously, it took longer.
His gaze finally returned to Stiles and he volleyed back, quietly, "What makes you think I won't be desperate by the time we get home without you having to do anything more than breathe and talk?" It had nothing to do with Stiles' scent, though that certainly didn't hurt, and everything to do with Stiles as a whole. "You don't have to do anything special -- though I won't object if you want to."
