During the time when the machine was being built , as I told you earlier about it that people wanted the stone so the would creep up to the top of the building to steal the stone. So one person who wanted the stone really hard he had many times almost had his hands on the stone. While these things were happening he saw that the stone was going to be used on Dave which made him very angry . This person was the Trainer's grandfather Robert . In order to take the stone away he made a few people turn against the trainer .
