Crossed my mind while watching the World Tour mini-arc that a couple of pairings should have been switched
Most of them made some amount of sense
Mimi/Davis- Both always say what's on their mind. Also the show probably wanted the lead of 02 to be in New York
Joe/Cody- Both have water Digimon and Cody inherited Joe's crest and you have the oldest with the youngest. Cody seemed to look up to Joe as a big brother like Yolei saw Mimi as a big sister.
Tai/TK- TK idolized Tai in the 01 days. Plus the leader of the first season and the real leader of season 2. (Well rewatching season 2 if often alternated between TK and Yolei,
Davis was a figure head. A leader in name only)
Matt/Ken- The lancers/lone wolfs/pretty boys/the ones who dabbled in the dark side.
But Yolei and Sora; um yeah Yolei inherited Sora's crest but they don't have much in common other than that and bird Digimon.
Kari and Izzy is even more random.
Personally it should have been Yolei/Izzy because they were both the computer whiz of their respective teams (and Yolei seemed closest to Izzy) and Kari and Sora because they're the respective team moms and have had been teased with both their team's respective goggle head and Ishida/Takahaishi brother
Also reminded me of how Cody should have gotten Love and Reliability (Sincerity in Japanese) and Yolei should have gotten Knowledge and Sincerity (Purity)
