Being a coward is a big part of Skylar's character (which he is trying to break by confronting that guy who copied his notes for example) but it's not an excuse to bring others down with you when you're entirely responsible. This being shown in comparaison to Cirrus not hesitating a second to take the blame is sad. Cirrus shouldn't have to self sacrifice (especially his education) because this isn't healthy. Skylar shouldn't avoid the problems he created out of fear and feel guilty only when he learns that there were consequences..
It's hard to see how these two are anything but *not* made for each other when the authors keeps showing how everything about them contradicts in such unhealthy, unworking ways.
