Plot
On the rooftop of the Looker Bureau, Liko and Dot deliver a drink to a depressed Navie before sitting down with her. In an attempt to distract her from her feelings, Liko asks what kind of Pokémon she likes, but upon pondering on it, Navie cannot decide on one and instead asks the other two how they chose their first Pokémon. Liko reveals that Meowscarada was given to her during her school interview, while Dot says Quaquavalchose her when she couldn't choose on her own. Navie then explains that because she loves Pokémon so much, she couldn't decide on one, so in order to take hold of her dream, Emma gave her a Dream Ball, which became extremely important to her. Meanwhile, on the Brave Olivine, Ditto is determined to return the Dream Ball to Navie and transforms into Noctowl before flying into Lumiose City.
The following morning, Navie decides not to join Emma for her morning patrol, still depressed from losing her Dream Ball, but changes her mind when the latter suggests retracing their steps along the route they used to find Carbink to look for her Dream Ball. She energetically greets everyone else in the Looker Bureau before being joined by Emma, who ensures everyone is ready for patrol. Elsewhere, after spending the night as a rock, Ditto is woken up and transformed back after getting tickled into sneezing by a passing Flabébé. It then begins its search for Navie by asking the wild Pokémon if they had seen Captain Pikachu. As Emma said, the group retraces their steps from the previous day, but while they don't find the Dream Ball, they find a trio of Trubbish, whose path is blocked by some sludge piles. Dot is asked by Emma to have her Quaquaval clear the way, and the Dancer Pokémon does so by using Aqua Cutter, making the Trubbish happy. Later, they come across a group of Budew, who are being chased by an aggressive Litleo. Cap and Sableye step up to protect the Bud Pokémon, forcing the Lion Cub Pokémon to retreat. Relieved to no longer be pursued by Litleo, the group of Budew cheerfully go on their way. Afterward, Emma's group comes across a group of worried residents, one of whom explains their apartment building is experiencing a blackout. To help them, the detective brings out and Mega Evolves her Ampharos into Mega Ampharos to restore power to the building, to Ult's exasperation for going over the top again.
After the residents thank Emma and Mega Ampharos for their help, the group decides to take a break at a plaza, where Navie realizes it is where she met Emma for the first time, revealing that she found Emma playing with Mimi and saw them having so much fun that she couldn't help but join in. Having spent so much of her life around Pokémon, Navie decided to join Emma as her assistant when asked. At that time, Ditto, who is traveling on top of a Dandy TrimFurfrou as its hat after becoming exhausted, spots Navie and the others and directs the Poodle Pokémon to them. Emma's Espurr, Mimi, senses Furfrou coming, thinking it is a threat, and Emma warns Navie, who gets startled by Ditto launching itself at her. When the Transform Pokémon returns the Dream Ball to a grateful Navie, the others realize she must have dropped it in the Brave Olivine before Ditto collapses from hunger.
After replenishing its energy with Navie, Ditto goes to play with Meowscarada and Sableye as Liko and Navie watch. When it transforms into Meowscarada's tail, Liko explains to a surprised Navie that Transform is Ditto's signature move, making the younger girl a little envious. Ditto then invites Navie to play with them, which she accepts cheerfully. The patrol resumes with Ditto joining them and Navie taking the lead, now back to her cheerful self, before they decide to return to the Looker Bureau. On the way back, Navie expresses her desire to visit places she has never been to and see Pokémon she has never seen in order to realize her dream to Ditto, which Mimi picks up on with its power.
Once they return to the Looker Bureau, Emma expresses her gratitude for the Rising Volt Tacklers' help with the patrol and finding Navie's Dream Ball while serving Lumiose Galettes. Roy enters the building, revealing the airship is finished with resupplying, which means it is about time for the four of them to go back to the Brave Olivine. Hearing of their departure, Navie becomes sad, but puts up a smile while saying goodbye, not noticing Mimi is picking up on something and sharing it with Emma.
Navie after catching Ditto
In the evening, Liko, Roy, Dot, and Ult return to the Brave Olivine, ready to set off again, while Ditto looks back at Lumiose City. At the same time, Emma joins Navie, who is using her telescope to find the Brave Olivine. She tells the younger girl she has found her dream, revealing Mimi had told her about Navie's feelings earlier. Emma admits she has been overprotective of Navie, but realizes it's time to let her pursue her own dream. Seeing Navie's excitement and newfound purpose, she decides to support her choice even though she feels it is earlier than she'd hoped. She acknowledges that Navie would eventually leave to follow her dreams, and that moment has finally arrived. Holding her Dream Ball, Navie chases after the departing Brave Olivine with Emma's blessing.
Ditto is depressed about leaving Navie, but Pawmi and Snorunt point out something to the Transform Pokémon. Climbing onto the rail, Ditto sees Navie running toward them desperately. She cries out for the Brave Olivine to wait for her, but the airship flies off into the distance, leaving Navie devastated. As she cries, a Pokémon's cry in the distance makes her look up, and she sees Ditto flying toward her as a Dragonite. Navie embraces Ditto when it lands in her arms, tearfully thanking it for coming for her before revealing her intention to be with the Transform Pokémon and the Rising Volt Tacklers. The two are joined not only by Emma, but also the Brave Olivine, which has turned back. Liko, Roy, Dot, and Ult join the group on the rooftop, reassuring Navie she would be fine with Ditto by her side. Navie asks Ditto, after a small push from the Transform Pokémon, if it would stay with her, and it happily accepts. Navie then catches Ditto as her first Pokémon with her Dream Ball before asking the Rising Volt Tacklers if she could join them on their adventures with Ditto.
During the next morning, Navie greets Emma in a new outfit the latter bought for her before receiving a Rotom Phone in preparation for her travel, much to Navie's excitement. The two visit the Brave Olivine, where Emma entrusts Navie's care to the Rising Volt Tacklers. The airship takes off afterward, with Emma and Mimi bidding Navie and Ditto safe travel.
