It had been awhile since Roger had gotten back on the broom. But it was his old Quidditch pride showing, that he was happy to be Captain of a team again. And he was equally pleased that Alicia was his opposing Captain, since she probably hadn't played a game in awhile.
And this was just for fun. It was to honour a friend. But Roger was still competitive too. He was quite pleased when Adrian and Cade wanted to play for his team. They weren't on his team during school, and they weren't Chambers and Bradley, but they worked together, and as an Auror, you needed to work well with your colleagues.
When Alicia called the start of the match, Roger kicked off and lead the formation. He heard Angie calling to Cade, and Roger just yelled back, "Don't let the girls intimidate you."
