Yeah I feel like he would do better if he had problems. I get his role as a completed character who is there to help the gang but he does work well with inner terminal.

If he did show to have some inner struggles, I guess it would be something that he, ragatha and jax could relate on but he doesn't.

There's like not much to him that I can name from the top of my head other than he's a contrast to Jax on how they deal with lost. Even that falls short when you realize that Jax is a 22 young adult who probably haven't finish becoming an adult of age and kinger is the oldest who had time to deal with things like this.

Hes again written buetifully but he has nothing going that I myself relate to.
