The original episode begins with the last few scenes of the previous episode (with the Kaiser revealing himself as Ken and departing). This is cut in the dub in favor of beginning with the scene with Wormmon and the Emperor.
Where did this "a first generation Digivice can only enter a Digiport that's been opened by a D-3" thing come from? Tai entered the Digiworld all by himself in the first episode, and nobody acted like these were unusual circumstances. Tai could enter in the first episode because that Digi-Port/Digital Gate was already open. That's why Tai tells Davis, "Never stay too long." The Digi-Ports open and close randomly all over the world (Mimi and Michael also use a naturally-open gate), and if you miss your chance, you're stranded. Izzy also points out that "the gate has never been open two days in a row." (I don't remember how well this was explained. You kind of have to piece it together, but it's All There in the Manual, anyway. The audio dramas spell it out.) As to the why: it's because the writers wanted to focus on the new characters. As soon as the "we can't evolve because of the control spires!" excuse dried up, they added the "we can't evolve because we don't have our crest powers! " excuse.
The D-3's are not always able to open the digiports as seen in episode 13. But as that episode is a Big-Lipped Alligator Moment, it is hard to tell if that happens more often. Not really episode 13 was before they really set that idea in stone, as beforehand they didn't even list opening and closing gates as one of their functions, Contrary to popular belief except for the important parts of the Digimon Kaiser arc, most of 02 wasn't written or thought up ahead of time.
Actually they point out that D-3's have that power within the first few episodes or so.
Back to the thing about the Gate not opening in episode 13, it's established that the Digital World has some guardians - Gennai's faction, the Four Holy Beasts (although they were sealed at the time, and thus probably couldn't do much), that 'entity' who spoke through Hikari back in the first season, the Crest Powers as of around two years before 02 begins, and probably more who we haven't met. Perhaps one of these factions 'sensed' that the Dark Ocean beings were on the move, but not why, and so locked the gates as a form of antivirus or something. Granted, it locks the Chosen out too, but if anything this was helpful in itself since Hikari wasn't actually in the Digital World that time anyway.
Checking back with Digimon Adventure I noted that Taichi opened a portal to the digital world in episode 21. That gate appears to be a side-effect to evolution rather than a purposely opened gate. Though in the finale of 02, normal digivices were also able to open gates (though there had to be a lot of them). My guess is that the boundaries between the real world and the digital world were a lot more damaged in season one than they were in season two, so less power was needed.
The gate opening in episode 21 was because the barrier between the Digital World and real world was weakening due to Apocalymon's influence. Hence all the Digimon breaking through to the real world...kinda.
That does not change that fact that gen1 Digivice opened the gate.
The gate was already open because of the broken barrier. The gen1!Digivice simply caused the open gate to manifest in a physical form that Taichi and Agumon could cross through.
Anyone find the original Digidestined's reactions to the Digimon Emperor lacking? You see Tai tell them that the digital world is being taken over and their response seems pretty lackluster, even taking into account that they are older you would still think that they would be more involved than they are. Apart from their cameo appearances in taking down the villain of the day in their designated episodes they pretty much leave these new kids to deal with these problems all on their own, even if they are arguably more experienced and could help more then they actually do. Matt talks about how he can't worry about the digital world anymore because he has to practice with his band and Sora just tells Izzy and Tai to "keep them updated" but they all appear rather hands off. All the while their partners in the digital world are being kicked, beaten and enslaved by a madman. What gives? You'd imagine they would be more proactive than they are considering the digital world is under attack. After 4 months of waiting it takes Kimeramon attacks for the children to set up a serious attempt to stop the Kaiser. And how long does it take to defeat him? About 2 days. They should have nabbed him around episode 5.
The Emperor was really more an annoyance than anything else. The Dark masters were a serious threat, Ken was an annoying little bitch on a power trip. Until he created an Ultimate level weapon for himself to go on a rampage with he's really just a minor nuisance. Sure, he's a problem but there's already others in place to take care of it and they seem to have the situation under control and the older kids always help out when asked or are presented with a problem. That pretty cold. That's like saying that that dictator in are backyard is only worth sending in the rookies because taking over a land area the size of a medium country is so blasé.
If you think about it, the children who act distant/prioritize the real world (Mimi, Sora, Joe) never really fell in love with the digital world in 01. Obviously they loved their partners, but besides that they probably didn't want to get caught up in the digital world again unless it was necessary. What they went through wasn't exactly pleasant. However, Tai and Izzy were always more interested in the digital world. Matt wasn't, but he's more invested because his brother is one of the new Digidestined.
Which actually goes against a very big part of their development in Adventure, when EVERYONE decided to return to save the digital world because they felt that it was their RESPONSIBILITY. Bad experience or not it doesn't erase the fact that they felt that digital world was their responsibility. However, come 02 this was thrown out.
The main purpose of a Digidestined is to aid his/her partner in digivolving via a Digivice and/or Crest. I think it was mentioned here somewhere that the original partner Digimon had gotten strong enough to be able to digivolve to Champion on their own without the use of a Digivice as shown by the presence of Greymon, Birdramon and Kabuterimon without their partners. Without the requirement of a digivice for digivolution, the original Digidestined's presence in the Digital World becomes moot. The new Digidestined, on the other hand, are needed since their Digimon are incapable of armor-digivolving without the Digimentals stored in their D-terminals and later their Digivices for digivolving which is why they were assigned to the Digital World. In addition, there's also the matter of a D3 being needed to travel between worlds. Supposing one of the original Digidestined came along with the new ones and got themselves separated from the rest, they would find stranded themselves without a way to get home. Besides, it's not like they're completely apathetic to the fate of their partners. Tai didn't hesitate to go back to Digiworld when he heard Agumon calling out for him and after Agumon was captured by the Digimon Emperor and the same thing for Sora.
This isn't true, while the original chosen children's Digimon can evolve to champion on their own, that only because they have the experience to go that far. They can't go beyond that without the help from their partners, which actually isn't a problem if one of them destroys a dark tower/control spire. Not to forget, Hikari and Takeru then technically use all of the digimentals, while Izzy can is compatible with one of them. Also that doesn't do much to excuse the half of the story either, In other words the new kids really weren't needed, that's the reason why the show added the restrictions, that previously were not there.
A few things. First, the children didn't know at that point that Digimentals were interchangeable - they only ever discover it in one of the drama CDs, which may or not be canonical, but even if it is it doesn't seem to happen until at least post-Kaiser era if not post-season. Second, the older kids didn't seem like they could really do much about anything. They couldn't Evolve their partners in Kaiser-controlled areas, which at the start of the story seemed to be a pretty decent part of the Digital World. Mimi in particular was in America, without a D3, and so had to wait for natural gates to open if she wanted to do anything in the Digital World at all; she certainly couldn't show up on a regular basis, not unless she flew out to Japan every week or so instead of just the one or two times, or started staying there until the crisis was over, and there are plenty of reasons why that may not have been an option for her. Koushirou seemed to be doing what he could to help out in a support role, even if he couldn't do so every episode. That just leaves Taichi, Yamato, Sora, and Jyou, and they can be forgiven for relative inaction since not only are their partners mostly useless until areas start clearing up and they can use the Evolve-first-enter-area-after strategy, but they do try to show up every so often.
Let's remember just because Bandai created official evolution charts for all of the 02 partner Digimon and every responding Digiegg doesn't mean that's how it works in show. Let's also remember that just because the story seems to think things work one way in one episode doesn't mean it won't change its mind later.
