Simon was caught in a thunderstorm and a tornado was approaching him as he watched in the field.
Simon's dad quickly picked him up and threw him in a storm celler and told him not to come out as he was going to check on the neighbors. Scared and wishing for his dad,
Simon heard Pokémon voices and he could understand them. When the storm was over, people came to get him but the farm was destroyed. It is unknown if Simon's Father died in the storm or not.
