Tale's suggestion worked. Thanks
I think the game has some sort of cache I can't delete based on what quests you've done, before I had him stuck in the spot, even if loaded a save where I killed him and loaded back to a previous save(before my character was aware of the quest) he would still be in the same spot. I loaded the same where I killed him did the Helios quest(holy crap, I had to cheat and use pulse grenades, I could not make the turrets kill the robots), reverted and did what Tale suggested.
Um, are stealth boys cannon in Black Isles' Fallout?
