How does Achilles help the younger children of Poke's crew get more to eat?

Achilles helps the younger children of Poke's crew get in line at a soup kitchen in Chapter 2. The problem had been that the older kids, known as bullies, would never let the younger children in line. The situation was survival of the fittest. Achilles picks a fight with one of the other bullies, and although Achilles has a crippled leg, he wins the fight.
