This is unlocked during the 2nd half of "They Open Doors". After completing the part with Oscar, you will be back at the crash site with Nima and Yoder. Inspect Nima's backpack to initiate a cutscene with Yoder. You will earn this achievement at the same time as Hatching a Plan.

EDIT: It is possible to the Chivalry conversation path 1st and then the greedy one and still get the achievement.
