Takato sputters a little at that.

"Guilmon, that wasn't.... I just got younger. Humans don't evolve or de-evolve like digimon." He turns to Ken and Wormmon and quickly explains. "There was an incident on the train recently where a lot of people became much younger for a day."

Guilmon wasn't convinced. "Takato got much smaller, just like Guilmon became Gigimon. And now Takato is back to being Takato, just like Gigimon is Guilmon now."
