Quotes
"If my calculations are correct, it's all your fault... The others needed D-3s in order to compete with you, so their subconscious minds must have somehow willed their digivices to chance, although I'm not sure Davis has a subconscious mind."
 * —Izzy theorizes about the existence of the D-3s.

"Huh? Tell me I'm not seeing what I think I'm seeing!"
 * —Yolei, reacting to seeing BlackWarGreymon appear in Kyoto.

Ken: "All right, Yolei, the rest is up to you now." Yolei: "What are you talking about?! Come back!"
 * —Yolei's not too happy about Ken seemingly abandoning her.

"When everything happened three years ago, I was right in the middle of the battle. Actually, my brother Joe was a little more involved. I was sort of helping out from the sidelines. It's not that I couldn't help them fight, it's just that I wanted to give the kid a chance to learn on his own."
 * —Jim has an interesting take on the events of Digimon Adventure.

Other notes

 * Izzy and Ken, while discussing issues concerning the human subconscious, cite fictional books and authors such as Singvold's "Theory of Ultimate Brain Power" (on which Ken had taught a class), Tissaro's "Strengthening Your Mind", and Korsky's "My Buddy, My Brain".
