If I Only had a Heart - S2.E32

Having developed a consciousness, BlackWarGreymon comes across Agumon and seeks his advice on his purpose in life. With BlackWarGreymon refusing to obey, Arukenimon creates Knightmon to destroy one of the Digital World's Destiny Stones. Though the DigiDestined attempt to stop Arukenimon, Mummymon, and Knightmon, the damage to the Destiny Stone attracts BlackGreymon and he shatters it.
