Okay so I count three different sets of Raiders telling the same story from a different perspective about this guy. He makes sound effects, pulls imaginary pins out of imaginary grenades, throws said imaginary grenades at Raiders which turns out to be rocks, then hops on his imaginary motorcycle -- which by the way doesn't start the first time he tries to start it -- then escapes on his imaginary motorcycle while making shifting noises.
All three Raider crews watch on in disbelief and through their stupification allow him to survive. Who is this unsung hero of the Commonwealth Wastes? There needs to be a random encounter in upcoming DLC. That is all.
