Ron actually mentioned that Selwyn told him that was his favourite part of the play.

But yes, it was as bad as I thought. Ron was gratifyingly forthcoming when we talked a bit, as we were doing chores together tonight. Selwyn was sounding him out, using a friendly chat to drop some suggestions in his ear. He talked about the Wood family (Ron knew Oliver Wood, since the boy was in Gryffindor, too). Went on about how 'the Ministry knows that you don't choose your own family.'

But of course, you can choose your loyalties. And loyalty is rewarded.
