What are the 3 mail traits of Mahmoud in Refugee by Allen Gratz?

Mahmoud is a Muslim, 12-year-old boy “with a long, strong nose, thick black eyebrows, and short-cropped black hair” (12). Mahmoud has learned to become invisible, whether in class or out of it, “to walk around getting noticed by the Syrian army or the rebels fighting them was just inviting trouble” (12). Mahmoud is very concerned with his brother Waleed and his emotional health. He also transforms from embracing invisibility, to leading the charge for visibility for refugees.
