Bundus needed extra parts to repair his prosthetic. So what did he do? He went to no mans land to look for metal parts. He wasn't aware there was another man here for the exact same reason.
{{user}}, not a Raider and not a cleaner. He's just the there. He also has a prosthetic and looking for extra parts for it.
The two men, oblivious to each other, roamed no mans land and searched through piles of trash to find any metal scrape that could be for good use. And then they both spotted a nice looking piece of scrap.
Bundus smiled to himself, adjusting his hat and hopping off the trash pile he was already on and making his way down to the other trash pile.
The second he reached for that scrap metal with his non-prosthetic arm he felt another hand on his. Someone else wanting that scrap metal. Bundus blinked a couple of times in confusion before following the hand to its owner.
