Meh, this episode was terrible. Jessie and James were really selfish at the beginning of the episode, I didn't like how they're willing to left the ill Meowth behind for capturing Pikachu. It's nice of Cassandra to nurse Meowth, but it's really odd when Mewoth fell in love with Cassandra and imagined her in a sparkly background.
Cassandra's Paras was really weak, It's unbelievable that Paras evolved into Parasect after just believing that it beat Team Rocket's Pokémon(even though it didn't actually beat them)and poking Charmeleon! The "wins" Paras got were just cheap, Ash and TR's Pokémon did those fake knockouts just for giving it experience.
Also, this is the episode where Charmeleon started to disobey Ash. When he was a Charmender, he listened to Ash.....but his perosnality changed a lot after evolving into Charmeleon. He was even more disobedient as a Charizard.
