Vincent was already bouyed by Owen's excitement, and he grinned before being positioned. As soon as Owen knelt before him, he guessed what was coming. Watching his progeny grabbing a box didn't surprise him at this stage, though his heart - already filled with love - swelled in his chest, warming him. Vincent took his time with the moment, holding the box and taking note the material that was used on it - whether velvety or shiny. He looked into Owen's eyes and grinned more broadly at his impatience, then did as requested, opening the box to savour another kind of moment. He lifted it out and saw the engraving, and the workmanship of it was impressive - though obviously done with mortal hands. He wouldn't have it any other way, because the imperfections of the work reflected a time when this was created for him by a mortal Owen.
"Maybe," he agreed, not thinking about 'cosmic' because all of his thoughts were about love and equality. The vampire who'd planned for this to happen (though knew the frail structure of such plans because it had depended very much on the human part), would not consider anything cosmic. He'd worked hard for this, not the universe. Him. He could hardly share such things with Owen however, who would only take it the wrong way and not understand it made him even more special. Perhaps it was cosmic then, that he'd been the one selected.
He slipped the ring onto his finger and could feel the engraving against his skin. Looking at it and admiring the fact he had a matching ring with Owen made this night more special. He'd not considered Owen would've planned such a thing. He was a beautiful, warm-hearted and compassionate young man - no, young vampire. The best kind of vampire to be.
"My love for you knows no end," he said quietly, and leant down to scoop Owen up to his feet, standing with him, so they could embrace tightly.
