At the rest stop, Team Rocket is sitting on a bench disguised as senior citizens to get a free food discount. However, when they see Ash’s group and Simon coming, they hide under the bench they were just sitting on. Simon directs the group’s attention to a bicycle and explains that it will help Pikachu recovery from his exhaustion. Ash hooks up Pikachu to the bike with the electrodes attached to it. The more Ash pedals, the more electricity is pumped back into Pikachu’s cheeks. Simon asks if they have any other Electric Pokémon that need to be recharged, but Misty and Brock tell him that Pikachu is their only Electric-type. Simon later explains to Misty and Brock that he won’t charge for the “recharge” and he’ll waive his translation fee, leaving Misty and Brock surprised. Overhearing the conversation, the Team Rocket trio decides to catch Pikachu while he is still low on electricity. The trio promptly bursts out from under the bench, sending Simon, Misty, and Brock flying up with the bench. The trio starts reciting the Team Rocket motto, but is interrupted by Simon, still thinking they are senior citizens, who offers them some more tea. The trio tells Simon that what they want is Pikachu before revealing themselves as Jessie, James, and Meowth. Meowth soon has an idea and orders his teammates into a huddle. He tells them that Simon has the ability to speak to Pokémon and says that he has never seen a human who could do that. Jessie and James ask Simon if he really can talk to Pokémon, to which he demonstrates by communicating with Pikachu, though Meowth can’t understand the pair. Ash asks Simon what Pikachu is saying, however Simon says that Pikachu needs to save his energy and then says that it’s almost impossible for most people to understand Pokémon language.
