Phanpy quits her alliance with Corphish, while Harmony tells Gastrodon about her success to join Kricketune's alliance as double agent, much to Tyrantrum's worry. The Final 17 (except Phanpy) have to do a surfing race, with Absol taking over Medicham's role as host.
Tropes
- Beach Episode: This episode's challenge is a surfing race.
- Both Sides Have a Point: Harmony had a point to ignore Tyrantrum's warning about exposure, saying that he's underestimating her and should be fine as long as Kricketune's alliance was focused on their conversations. At the same time, Tyrantrum had every right to be worried about Harmony's actions and learning the hard way from it despite Gastrodon's trust in her.
- Big "WHAT?!": Gliscor, Monferno and Mawile's reactions upon Tyrantrum revealing a Division Idol.
- Screw This, I'm Outta Here: Phanpy does this when the challenge started upon not being noticed as per usual.
- The Reveal: Just before the elimination ceremony, it is revealed that Absol is partially responsible for spreading the Delta Pokémon across the island on his commander's behalf.
- You Have GOT to Be Kidding Me!: Monferno upon losing the challenge.
