How would you describe Tick?

Tick Hassler is an older boy who comes from Ember. He is a charismatic and enthusiastic person who has a knack for getting people to join in his plans and projects. At first his projects are making improvements, but he then turns to organizing an armed response to the perceived unfair treatment of the Emberites. As it turns out, much of the conflict was actually manufactured by Tick. He leaves the group in disgrace after he is discovered.
