Detailed walkthrough
Upon entering the Vault-Tec Agricultural Research Center, whether or not during the Fertile Soil event, a small Vault-Tec holotape case will be on the counter, collecting the holotape from it starts the quest as the player characters learn of the Vault 76 overseer's journey to becoming overseer in the first place.

Once the first one is collected, head to Sutton to get the next one, from the Overseer's old house in the northern part of town. From there, travel to Morgantown to pick up the third one from Morgantown High School, and the fourth from Vault-Tec University in the lecture hall upstairs. Head down to Welch in the Ash Heap to collect the fifth one, and the sixth and final one around Abandoned mine shaft 6 near the Rockhound and summit of Mount Blair.

Listening to the holotapes, it is revealed that the overseer sacrificed her fiancé Evan to remain in Appalachia as Vault 76's overseer instead of transferring to Vault 101 with him due to Vault-Tec having been unable to give Evan a spousal exempt to enter Vault 76 with the overseer. When the overseer found him after leaving the Vault 25 years later, she was horrified to find he had succumbed to the Scorched Plague and become a Scorched. She could not bring herself to mercy kill him, so she locked him away and hoped that the Vault Dwellers could do what she couldn't and put Evan to rest, as his fate only steeled her resolve to secure the Appalachian Automated Launch System and its nukes and put an end to the Scorched Plague once and for all.

Grab the keycard next to the case where the overseer's last journal holotape was, use it to enter the door down the stairs next to it, find Evan sealed in a room behind a barred door as a leveled Scorched enemy, and give him the mercy he deserves, completing the quest.

Bugs
Upon entering the room in Mount Blair where Evan is found, he may already be dead, preventing the completion of the quest. This occurs if another player character in the same world instance completed this stage of the quest beforehand and the server has yet to refresh Evan's state. This maybe be resolved for some players by logging out of the server and logging in again.
