The people were fighting to take the shelters that Lyneth and Edith had provided. There were too many people and so few places, and nobody wanted to give their spots to those who already got theirs. They didn't care about older people, kids, or women, they only cared for themselves.
Since there weren't that many soldiers in New York, they couldn't contain or calm the people. Their instructions were ignored, and even if they used force, nobody would care and keep fighting.
"Look at those people. They dirtied and vandalized our buildings, and yet here they are, using our facilities with no shame," Lyneth said as she looked out at the street inside the car. "Once this is over, we can finally make this whole continent ours. There will be no one that can stop us now," Lyneth continued.
"Isn't the continent too big for all of us? What are we going to do with it?" Edith asked as she drove the car.
