Troublemaker? Naaaw, not at all. But he is going to by a little pushy with "kids" around, making sure they know what they are going into and making sure they understand the dangers. Basically, he won't go soft on the reality of things for them.

PS: Elrithos looks to be more of the cold and serious one, but not at all. He is very down to earth yes, but extremely polite and well mannered.
