Carmine and the BB League's Elite Four, Drayton, Lacey, Crispin, and Amarys become concerned when he begins using his new authority to bully other students out of the club.
Now humiliated in front of the school, Kieran scrambles to come up with a way to get back at the player.
However, upon reaching the furthest point in the Area Zero Underdepths, Terapagos shows more interest in the player than Kieran, forcing him to use a Master Ball he received during his time as BB League Champion to effectively steal it from them. However, when the player is still able to defeat him, Kieran, under a glory-blinded Briar's instructions, Terastallizes Terapagos and demands it battle the player again. This proves ruinous, however, as Terapagos turns on and attacks Kieran, destroying the Master Ball he caught it with and forcing the player to intervene. Terapagos soon proves to be too powerful for the player to battle on their own though, so Carmine and the player convince the guilt-ridden Kieran to help out, ending with it being caught by the player.
The shock of Terapagos attacking him forces Kieran to finally realize the error of his ways, so he resigns from the BB League's rankings and requests that he and the player start over as friends. The player presumably agrees, and they return to Blueberry Academy. Following these events, it is mentioned by an NPC in the Terarium's Central Plaza that Kieran has also begun taking time off from school altogether to try to rebuild his life.
