This chapter consists only of conversation choices, though it can conclude disastrously if the wrong choices are made. If you chose to take the rebreather in Depths and succeeded at all QTEs, an achievement/trophy can be obtained here. When the options come up, choose to tell Junior that there was a mist, but the survivors didn't breathe it in. The player characters will then present the rebreather as proof if available. Choose grab pistol to then save Junior. Take note that when attempting to obtain a bad ending, Junior can shoot the player characters if they choose to remain silent.
The next chapter depends on the events of Revenge and Distress Signal. If Alex decided to search for the generator, waited by the radio by himself, or died, then Olson will be the next chapter. If Alex is waiting by the radio with another character, then Matters of the Heart will be the next chapter. Both act as a finale for the game.
