S20E19 A Guardian Rematch! (Patreon)

Fixed microphone, Irene's mood. We talk about liking some of this episode, but not all of it. 

Ash really wants to have a rematch against Tapu Koko, but he’s not sure about his strategy. Sophocles, who studies Electric-type Pokémon, offers to help! After some research and training at Sophocles Lab, Ash and Pikachu are ready for battle, and so is Tapu Koko.
