Tag had no idea when Arresto Momentum was used. So, rather than answering and making a fool of himself he sat quietly in his desk. As well, so far, Tag liked this guy, and this class. He seemed relaxed and chill, Professor Fuller, so that put the little boy at ease. And once the Professor got a good round up of the answers, and whatever he would right on the chalkboard Tag would simply scribble it into his notes.

Class participation right there.
