Simply put... I'm verifying the nature of the relationship between humans and Digimon. Supposedly, we were called here for some great crisis, but we've seen nothing of the sort yet. Gazimon, take it, this is your bit.

Digimon can naturally evolve on our own without humans! But no matter who it is, each Chosen Digimon is stuck as a Child-level forever, unless the human is there to let them evolve, it's a stupid system that keeps us weak!

Right. What we're getting at is, in exchange for temporary strength, the bond between humans and Digimon seems to actually weaken the Digimon overall by blocking off their natural ability to evolve and hold an evolution permanently. You, at least, have a model of Digivice that allows you to be of actual use, showing powers a Digimon can't use alone, but those of us with this useless model have no such bonus. Which leads to my current theory, but as I couldn't test that properly on that... What was it?

Greymon. Will you learn the stuff I tell you already?!

Yeah, that. I'll acquire my data by watching you other kids do it instead. All you need to do is fight and prove your worth as a partner.
