AG040: Watt's with Wattson?

Synopsis
The time has come, once again. Ash was super psyched to have another Gym Battle. This time, it was with the elderly, yet hilarious, Wattson. The battle was short as Ash's Pikachu took out Wattson's entire team with just one hit each. Devastated, Wattson gave Ash the Dynamo Badge. Will Wattson recover from this, and what has happened to Pikachu?
