- Rui: I don't know why but... Ichijouji-kun is not a bad person.
- Daisuke: How's that possible tho? He's a meanie to the digimon and us, Rui.
- Rui: He... I think that Wormmon said he was pitying me before...?
- Daisuke: Huh...
- Rui: He... gave me this new outfit. And he was researching this eye thing too. I think it was to... help me.
- Rui: Let me try to talk to him, please.
- Daisuke: Do ya think it could work tho? He's unreachable, and won't come to help us. And Wormmon, he's...
- Daisuke: ... He sacrificed himself to save Ichijouji.
- Rui: I see... So he's like me now...
- Daisuke: Well, Ukkomon may be alive...! Because that eye is still in your face.
- Rui: Yeah, but... I mean that he's lonely now. I feel bad for him...
Another √02 comic, now about the post-Kaiser arc (between ep 22 and 24) and then Daisuke and Rui talking about Ken and how Rui thinks Ken was kind and helped him out of kindness. Daisuke is not so sure if this means anything, but remember that Daisuke says he heard something coming from the Digimental of Miracles before :).
So yeah, HERE he starts to get what the Crest of Kindness meant. It's just an extra flavor in this AU interquel.
