Despite Pansy's hints, Greg had never thought his mother was serious about trying to set the two of them up. It was ridiculous - Pansy belonged with Draco, and even though that wasn't happening anymore didn't mean Greg was going to try to muscle in. It would be... wrong. Pansy was attractive, and Greg loved her as much as he was conscious of loving anyone, but he couldn't imagine being married to her or having children with her. He trusted his mother - perhaps quite wrongly - to understand that and to find him someone he could have that kind of future with, though he was in no rush for it to happen right away.
Portkeys always set Greg a little on edge - he didn't like not knowing the exact situation he would be appearing into, but the lobby wasn't too bad. The sophisticated nature of both the establishment and the patrons meant it wasn't too loud, unlike the time shortly after the war that he'd apparated into The Hog's Head in the middle of a bar brawl and immediately had to leave again due to the shouting that had seemed completely overwhelming. He took Pansy's arm as he'd been taught to do, nodding at the people she greeted even if he didn't recognise them himself. "Do we get snacks?" he asked, without much actual hope - snacks were for Quidditch matches and the like, not for opera. Still, Pansy was used to him asking 'stupid' questions.
