Seeing as his second lesson with the younger students didn't go as planned Sean had decided to carry it on in the third lesson; it would enable the kids to actually learn something and it would also show them that he wasn't above carrying on with the previous lesson instead of showing them something new.
Sitting at his desk, the board behind him was empty except for the one word that he had written on it the previous lesson; Freezing Charm. If he had to teach the students that not attending his lessons meant that the kids that did would suffer then so be it, he wasn't going to let them fail after all and not attending even one lesson would make the child suffer during the end of year exams.
Relaxing in his chair, Sean decided that he would just get on with the lesson instead of forcing the kids to go through theory; they could do that in their own seeing as his was wasted pretty much.
