Chapter 9 Ryan refuses to be bitten by Laura
At the end of chapter 9, Ryan has to shoot the monster Chris? Ryan bled to death.

Chapter 10 Play Max and walk to the other side of the island? The scene that triggered Laura's reunion with Max (Laura went to the island because Ryan and Travis died)? Dance after watching the scene.
