Anita initially believed that going to the Trainer's School is something that they have to do because their parents told them to do so. She felt the same way as Kenny did. However, after seeing Max and Tommy help save some stolen Pokémon from Team Rocket, her views about Pokémon changed.
Apparently, she initially disliked Tommy because he prided himself on being the star student and she was tired of all of his bragging. However, her opinion changed when she saw that Tommy had a nicer side.
Pidgey was first seen on a field trip with Roxanne's beginner class, and then again when the class was trying to get used to Pokémon. During Team Rocket's attempt to capture the Pokémon from the school, Kenny told Anita to tell Pidgey to use a Wing Attack on the Wurmple shaped mecha, releasing the stolen Poké Balls in the process.
