James turned to Alastor without even thinking, and then looked out to the crowd, smiling again, hoping that very few people had caught his surprise.
He was already thinking of the consequences of this little announcement, and the fact that Severus would never be able to reach the podium for any reason ever again seemed a likely possibility. However that didn't mean that he couldn't have some fun.
He stood up and used to Sonorus spell. "Since Severus has decided to share the news with everyone, I'd like to propose a toast. To my brother, Albus, who's sitting right there. Al, stand up, I'm sure everyone here will want to congratulate you when we're done... with hugs, and of course, to Severus, my newest brother-in-law. I am very happy that you could find happiness in each other during such dark times. We wish both of you a long and happy marriage, and I'm sure that everyone in the family can't wait to tell you in person how they fell about this momentous occasion. Cheers."
