I have been theorizing for awhile now that the Other had the ability to create machines with the spark or at the very least transfer the spark into machine. My theories started back when The other transferred the Others mind into the Robot back in Sturmhalten. But this as a whole raises some very interesting questions. I have no doubt that the Baron would love to watch and analyze Agatha and her Dingbot's since he has such a fascination with the spark in general. Of course that would all hinge on him stopping his attempts at killing her.
