Ascended Fanon: Konaka gave this response when confronted with the fan hypothesis that Alice is a ghost.
Actor Allusion: Possibly to Bridget Hoffman, the voice actress for Jeri, also worked on another Chiaki J. Konaka production, voicing the eponymous Lain. Definitely in the case of Yoko Asada, who voiced Jeri in Tamers and Alice in Lain.
Creative Differences: Tamers owes its very existence to this. To recap, many of the staff including Konaka which were originally apart of the main staff for Digimon Adventure 02 were upset about the Executive Meddling and so they were about to quit the project even though they were under contract. So instead of letting them just leave and break contract, Bandai gave them and Konaka the next series, and then gave them the room to plan it out the way they wanted.
Depending on the Writer: Although at first glance the Ryo that appears in Tamers has a different personality from the one in the game, he was in fact written by the same person who wrote his character in the games, according to the main writer.
Mako is is T.K. in Digimon Adventure and MarineAngemon in this series for the English version.
Keep Circulating the Tapes: If you want to get the original Japanese dub but live outside of HULU's supported territories (the USA and Japan), you'll have to get it online from unofficial sources as the Japanese DVDs are out-of-print. The American dub got a complete season Region 1 DVD release in June 2013.
Marth Debuted in Smash Bros.: In the West, Kai's first appearance was a cameo in one of the later episodes. The Battle of Adventurers movie (were Kai is plays a role) wasn't released until years later.
No Celebrities Were Harmed: Notably Pajiramon, whose English voice is a homage to Kate Mulgrew - Captain Janeway of Star Trek: Voyager. Mary Elizabeth McGlynn, who voiced Pajiramon and was this season's voice director, had guest starred in a Voyager episode.
Shrug of God: Chiaki J. Konaka on whether or not Alice is a ghost.
Talking to Himself: Aoi Tada as Terriermon and Lopmon; Yuka Imai as Renamon, Rika's mother, and Rika's grandmother; Steve Blum as Guilmon, Kenta, and Yamaki (all except the latter are in Japanese version). Ebonwumon has one head does most of the talking, including on behalf of the other.
Jeri and the D-Reaper, naturally. That was kind of the point.
Word of God states that Impmon was originally conceived as Takato's Digimon! When that was shot down, Impmon/Beelzemon was originally intended to be the Big Bad of the series, but was replaced by the D-Reaper and became The Atoner instead. This may explain why Impmon is portrayed in typical Big Bad fashion in the earlier promotional material.
Tamers was originally planned to be a direct sequel to Adventure continuity.
The earliest design notes referred to Rika's partner as "Lunamon." That name was used years later for a different Digimon.
Word of God: Arguably has the most All There in the Manual info out of any Digimon series due to Konaka's blog being publicly available and packed with information, and with an English translation to boot so that non-Japanese speakers can read.
Writer Revolt: Konaka wasn't pleased when Bandai forced him to includeRyo Akiyama in Tamers. While he did comply by adding in Ryo as they wanted, Konaka deliberately minimized the amount of screen time and importance that Bandai wanted him to have in Tamer's plot.
