What happened when Tino, Thresa, and Henry came over Paul's house?

When the group is out in the backyard, Erik and Arthur come through the gate and start making fun of the kids for being farm laborers. Paul is furious but he doesn’t know what to say. He tells his friends to ignore them, but Tino stands up to Erik. As he does, Arthur takes his blackjack out of his gym bag. Erik tells him to put it away. But then Tino tells him that he saw his flop on the field. He starts to make fun of Erik. Erik hits Tino across the face so hard that Tino spins around before he hits the ground.

Paul is horrified, but he’s still paralyzed. He doesn’t know how to stand up to Erik, who looks into his eyes for a moment in a very strange way. Paul thinks he sees fear—or maybe even sorrow. Erik walks away, leaving Paul and Tino on the ground. Tino is bleeding. He doesn’t want any help from Paul.

okay thank you very much
