Tristan wheeled over to the nearest table and rested his elbows on it, his head in his hands. He needed a moment. Just a moment. Time to sort through his thoughts. If Alec was Dark's son, and Tristan his uncle, did that mean Dark was accepting Tristan as a part of his family? A brother-in-law, as it were? He wasn't sure how he felt about that. Part of him yearned to be a part of this family, a real part. He knew that Dark and Daizi had both made comments in the past about accepting him, or something similar, but he'd never really taken them seriously. Why? Because he was afraid. His only real, defining example of family had been the one he'd grown up in, and he was terrified of that sort of commitment ever again. Which, logically, he understood was completely a failing on his own part and why he'd never been able to really keep a girlfriend for more than a few months (though there were often other valid reasons to end the relationship). He let his own fear guide his life, cutting out people who cared because he was afraid. Yet, here was someone who'd shown up every single time he had a need, who'd never asked for something in return, and who'd now gotten involved in something potentially dangerous, and why? To help him. To be there for him. Dark was a hero in Tristan's life, and Tristan could never, ever tell him that. For one thing, Dark would probably give him one of his withering looks if he did. But Dark... Dark was family. Tristan was finally seeing that, finally accepting that in a way he'd never been able to before. Alec and Xander were easier - Xander barely felt like he had a relationship with him, though he was always very civil now that they'd gotten past the bumpy stage - and Alec was more like a younger friend. It was a little easier to feel uncle-ish with him. And Daizi was always loving and caring. It was still strange to think, but maybe, just maybe, he could accept it.
He took a deep breath and straightened. He felt ready to go home now. Ready to drive responsibly. He wheeled to the separation and pushed the bead curtain aside. "Could you, if it is not too much trouble, lock up for me?" he asked Dark meekly. "I think you are right. I should head home. Are you okay here?"
