This sparks an argument between him and T.K., who remains hopeful. Davis lunges at T.K. and when Kari and Yolei try to break them up, it reminds Tai and Matt that one of the reasons they are such good friends is how much they fought when they were younger.

After a while of travelling, Cody's D-3 starts beeping and they notice the Crest of Friendship carved into a cliff face nearby. They soon find a Digi-Egg with the same symbol on it. Matt is the first to try and lift it, but he has no luck. He is followed by Cody, Tai, T.K., Kari and Yolei but no one is able to lift it. Finally, after being somewhat forced, Davis tries, though clearly not as hard as the others, and it yields the same result. Suddenly, a terrible screeching noise fills the air and it turns out to be from the bug Digimon Flymon, who immediately attacks the group, injuring. quickly armor digivolves to and counters back. follows suit but neither can finish him off because of the ear-piercing noise. While everyone is busy covering their ears, the wounded Patamon is kidnapped. As everyone chases after the Flymon, Ken appears on MetalGreymon and attempts to put a Dark Spiral on the kidnapped Patamon.

and armor digivolve into  and  to help Garurumon try and destroy the Dark Spiral on MetalGreymon, though Davis is still too scared to fight, in fear of hurting Tai's partner. Flamedramon then reverts to Veemon, claiming that Davis doesn't understand true friendship. When Veemon is put in danger and Davis does nothing to help, the others scold him about his lack of trust in his friends. He has an epiphany and the Digi-Egg of Friendship appears in front of him. Veemon uses this new Digi-Egg to digivolve into. Everyone is surprised, including Ken, who has MetalGreymon attack. Raidramon counters with Blue Thunder at the Dark Spiral, but it doesn't break. With some encouragement from the group, Davis rides on Raidramon and the two continue on the offensive. Garurumon uses his Howling Blaster, distracting MetalGreymon long enough for Raidramon to use his Thunder Blast, which is powerful enough to shatter the Dark Spiral from MetalGreymon's arm. Tai is thrilled to be reunited with the now normal Agumon and Ken flees on an Airdramon. After the group returns to the real world, Izzy sends Tentomon to spy on Ken. Davis is happy to now be in possession of two Digi-Eggs and Matt gives him a noogie, saying that he's officially part of the team now.
