DP055: Throwing the Track Switch

Plot
Continuing the journey to Veilstone City, Ash and the others are at a Pokemon Center watching a contest on TV, where they see Kenny win his second ribbon, which upsets Dawn. They then reveal that the next contest will be held in Solaceon Town and Dawn decides to start training for that contest. Ash also decides to train for his next gym battle. Zoey arrives at the center and decides to help Dawn train. During the training, Ash's Aipom and Dawn's Buizel are distracted by the other's training, and so Zoey suggests that they trade them. Ash and Dawn start to think about the trade, and when Team Rocket attacks, they decide to use the other Pokemon as a test to help decide what they should do.
