Sirius and Remus are both Professors at Hogwarts, Sirius the Astronomy Professor, Remus the DADA Professor. They're married, publicly so. There are two boys, one in third year and one in fourth who are copies of Sirius and Regulus as children. “Remus, for the last time, we are not taking them in. We can't raise two troubled teens!” Sirius sighed, pacing back and forth in their living quarters.
