The District 3 male's uninspiring brown hair is nothing special in District 3, or anywhere else for that matter (See what I did there?). It is a simple color, and no one chooses to describe it as 'chestnut' or 'chocolate locks' - it is always just brown. His eyes are the color, but at least stand out a little more and carry a glint of intelligence that always tells people he might be hiding something. His short frame is what makes people underestimate him.
The District 3 male's smart. Well, all District 3 children are classed as smart, but even they know Noah is something speacial.
