JUST A THOUGHT:
Shawn Elliot- To a certain degree seems to me, at least, similar to a soldier. By his latest appearance on 1up Yours, he has expressed himself incredibly eloquently, yet has retained to render himself funny. That said; a solider can joke with the guys, drink a bit and have some fun, while dedicate all his senses as total warfare slowly consumes the attention of him and his comrades. And by that; he is innately very competent at his craft, and carries a considerable amount of charisma along with it.
