Ruby and Sapphire train together with Plusle and Minun in double battles against Tate and Liza on Mirage Island, both working very hard. Sapphire's Lairon evolves into Aggron, and Sapphire manages to teach her Blaziken Sky Uppercut on Ruby's suggestion. Sapphire promises to not be a burden to him in the upcoming battle against Kyogre and Groudon.
Time has slowed, so that even though seven days of training have passed on Mirage Island, only one day has passed in real time.
Observing how well Ruby and Sapphire work together, Juan decides to start and different kind of training: training of the "mind," testing their hearts, or intuition. He puts a coin in one of his fists and has Ruby try to guess which hand the coin is in; Ruby gets two out of six right. He does the same to Sapphire, who guesses six out of six right. Juan explains to them that in the heat of battle, one cannot always make logical analyses and decisions.
After Juan notices Sapphire falling asleep where she stands, training ends so that she can have a nap. While she sleeps, Ruby approaches Juan and tells him that he hates being left in the dark. Ruby, lifting a transformed hand, reveals that he and Sapphire have accidentally absorbed the Jewels.
