Some more noise related stuff
Free Drones & ProtectorateYou can use sound to lure a Free Drone to opening this door which normally you can only do from the other side.
Proceed to lure them out with sound and kill them out of sight of each other. Killing Shred sets off the flag for the Free Drone faction turning hostile towards you. To circumvent this you can use traps to kill him as the territory is uncontrolled.
Later on in the Protectorate quest line you are given access to the Free Drone base. Speak with Trenton and immediately be given the Junkyard fetch quest. Alvin Bates will speak as Unknown. I'm unsure what actually happened to him. Either he was never spawned due to skipping over quests or that progressing the Protectorate quest line killed him off/escaped.
As Epione Lab has already been destroyed you cannot complete the quest as the area is inaccessible having already taken place in the Protectorate quest line.
Marcella Green will initiate the spy accusation each time she is spoken to.
