They track Black to a restaurant in Striaton, where they spot him having tea with a girl. Bianca is immediately indignant, unable to believe that Black's been slacking off, dating a girl, while they've been struggling to catch up to him. Cheren comments that it doesn't look like a date him, but Bianca wants to follow White as she leaves. Cheren pulls her into the restaurant, and Bianca immediately begins to interrogate Black.
Cilan, Cress, and Chili watch the trio and decide to give Black his gym battle, as he's been bothering their other clients. They skillfully make tea for the three as a prelude to the battle. Cheren and Bianca have barely a moment to enjoy their tea before Black leaps up, ready to fight.
The gym leaders reveal a stage curtain with a water symbol on it, telling Black they'll be waiting for him in the back once he's finished the gym puzzle. Black moves to step on the grass button but Bianca reaches the fire button first. Black and Bianca begin to argue fiercely, escalating to a brawl between Tepig and Oshawott. Snivy soon joins in.
Cheren interferes, calling Black out on his thoughtless, selfish behavior. He tells Black about the broken pokédexes.
The conversation is interrupted by Chili appearing on a screen, telling them that Black has been disqualified because someone other than the challenger participated in the puzzle. He waits a moment for Black to slump over before revealing that he's joking, and that they, the gym leaders, have decided they want to have a triple battle against the Nuvema friends. Chili tells Black to teach Bianca as they go.
Black demonstrates Oshawott's resistance to fire and weakness to grass. They and their Pokémon begin to cooperate, quickly reaching the back where the gym leaders are.
