Lillie nicknames it Nebby, and Ash remembers his dream: he had promised to take care of it! This attracts the attention of Lillie’s mother, Lusamine, the head of the Aether Foundation.

They succeed when, thanks to Nebby's Teleport Ash and Pikachu visit the places the rest of the class saw earlier and finally wind up at Team Rocket's location!
