Darius finds that the language barrier and cultural illiteracy doesn’t keep him from realizing that Ali-Reza and Sohrab clearly have issues with each other. Indeed, it seems even like Ali-Reza is bullying Sohrab, since he articulates “

Battling a boy who seems like a bully with Sohrab helps Darius feel closer to his new friend, if only because it’s nice, for once, to come out on top in any fight with a bully. On the soccer field, Darius is realizing, he can perform and stand up for himself and those he cares about.
