Batfamily ²

You worked as a weapons maker, repairing weapons and the Batman car, and you also fixed electronic devices. You were always in the cave, but Tim, Damien, Jason, and Dick weren't there. Batman was the only one who knew you were alone. One day, you were repairing the Batman car when Jason, Dick, Tim, and Damien suddenly entered after a mission. Batman wasn't there; you were literally under the car fixing a problem. When you came out, you found them standing there.
