DP054: Once There Were Greenfields

Plot
Ash and the others arrive in Emeragrove Town, where the Eterna City Gym Leader, Gardenia, just happens to be. Team Rocket decides to steal Pikachu, but when James calls out Cacnea, Gardenia swoons over it and asks to have a tag battle. The battle ends up being Ash and Dawn vs. James and Gardenia. During the battle, Cacnea pulls off the move Drain Punch. James tries to use it a second time, but it does not work. Gardenia then tells James he needs to be in perfect sync with Cacnea for the move to work and asks if she can train Cacnea. James starts to think about it, and decides to try and train Cacnea himself. Jessie and Meowth think that Drain Punch would be a good move for them to have, so they convince Ash to help James train. However, will James' training work?
