Remus/Sirius + Tonks
Remus had to admit, he was extremely impressed at how Tonks and Mac had pulled this off with one day's notice. True, they already had everything since the wedding had been postponed a week, but obviously there were some things that had, had to be done spur of the moment and they had pulled it off quite well. While Remus was happy for Tonks and Mac, there was still a part of him that worried for her, because they had only been together a short time and she had still, had feelings him only eight months earlier. Seeing them together, it was clear that they loved each other, but that wouldn't stop Remus from worrying anytime soon; he was just a natural worrier.
Throughout the ceremony, Remus had glanced, quite often, at where Sirius sat after giving Tonks away, hardly able to wait until they put their plan into motion at the reception. Tonks was certainly in for a surprise. Now that the reception had arrived, Remus was sat at the table he'd been assigned to, simply watching everyone else and waiting.
