One of the children's Dark Spores grows into a Dark Flower, which is harvested by Oikawa despite the DigiDestined's best efforts to stop him. Cody's grandfather tries to convince Oikawa to give up villainy, but fails. Before Oikawa can kill him, however, BlackWarGreymon takes the fatal blast. The dying mega uses the last remnants of power to seal the digital gate at Highton View Terrace. Also, its revealed that Oikawa is actually possessed by a dark force, one that BlackWarGreymon recognizes but doesn't identify before his death.
