Bossuet has no luck and so makes good ‘luck’ for others. When Marius does not come to class, what good luck he has that Bossuet always answers for him in roll call. When Grantaire is sad, what good luck he has that Bossuet always brings him to the Musain and sits him down with Joly. When Combeferre loses his spectacles, what great luck he has that Bossuet is interested in his daily happenings and would like to accompany him to all of them. Bossuet is everyone else’s good luck charm and he is so on purpose.
