I'm trying to do a Pacifist run in Fallout 3. I need to exit the simulation and finish the quest tranquility lane without killing anyone either way. I can't kill them as the pint-sized slasher as the run required the people killed counter to be zero and I can't kill them via the failsafe because that's against the spirit of pacifism. I tried setting the stage to just after the massacre and Betty, well, she did that thing where the screen kinda zooms in and there's no dialogue and you get ejected.
WIthout a mod to materialize the door and complete the quest I'm stuck.
