When ED-E's circuits burned in the fires of the Divide, there was one small part that held on until the end. It was the fragment that held the Old World memories and the words of his creator in his last moments. At lest that would've happen if a weird man didn't pluck ED-E out of Earth and drop him in the middle of a strange place for some bizarre reason.
Rated Everyone (yes a Fallout crossover that's rated everyone). This is just a silly little idea in my head. Hopefully y'all will enjoy it. Also thanks for HeavyMetalCommunist for proofreading.
