S20E31 The Island Whisperer! (Patreon)

After 30 episodes, we finally meet the Kahuna Olivia! Irene is a big fan and talks about why in this episode. We also can't help but notice this episode has a lot of awkward dialogue choices and decision making from the characters. 

On the boat to Akala, Ash and Olivia discover a Wailmer, trapped in the rocks by an angry Bruxish! Everyone works together to drive Bruxish off and get Wailmer free, and when it starts to sink, Popplio comes to the rescue, floating it up to the surface in an impressive balloon. That night, Nurse Joy hosts everyone at the Pokémon Center, and there are more exciting adventures to come!
