I am playing through Aza's quests and I am at the n ray range. While going through it I killed everyone that I could find. When I got to the room that has the barred door with archivist trammell inside there were 2 people in the big room and 2 behind the door. I killed the 2 in the room and proceeded through the rest of the building and talked down Victor and had aza cut him up. Then as I was leaving I remembered there were 2 people left so went back to see if I could get into the room. After searching the entire building for a couple hours I decided to look it up. I find that archivist trammell was supposed to be alone. While all this was going down the enemy that spawned in the room with trammell had killed trammell. So my question is, is there a way to rectify this or am I cut out from Aza's quests. ps I dont have any saves from before killing Victor.
