Scenario: #5 - Bygones
During this scenario you must keep Nima talking. When she looks out at the island and says it has changed, make sure you don't say "we don't have time". Now keep picking every option on the left. Do not ever choose "Enough talk". Also refrain from choosing the "(listen)" option to avoid being cut off. The achievement unlocks after Gerry apologizes about the island.
