First of all, feel free to move this/change the title/whatever as necessary, as I am covering a handful of topics.
OK. After spending hours reading the
Principles of Time and Dimensional Travel page and days contemplating, I have a few questions. Let's get right to it.

Kid1) For clarification, how many versions of Kid exist in Chrono Cross? From her birth in 1004 AD (KT-2) to 1020, that's 1. She then travels back in time to 1010 to save Serge and ... I'm lost. I presume she returns to 1020* of the new timeline in Another World, while a new Kid continues to live in Home World. We're now in Mid Dimension Timelines (I'll refer to this one as KT-3). The Kid of HW, according to Kato, is up on Zenan doing who knows what; probably being a pirate. Meanwhile, the Kid of AW is the same who saved Serge in 1010 and calls upon him in 1020 ... right? The story progresses until Masa and Mune send Serge to 1015 to save Kid (of AW only). When he returns, Serge is in KT-4 and a new Kid (the one he saved) now lives. That's 2 in AW and 1 in HW (in total, among KT-2 to KT-4). Activate Chrono Cross, shit happens. Am I getting this right?
*The Compendium states she traveled back in time sometime after 1015. I'm saying 1020 for ease of reference.
2) How did Kid travel to 1010 to save Serge? I do not believe Belthasar ever contacted her, because she does not recognize him at Viper Manor. So my only conclusion is that she used a Time Egg, the same in her possession when Masa and Mune saw her in 1020.

Dimensional Split1) Is the split between Another World and Home World a branching of the dimensions, starting at 1010; or is it a division of the dimensions throughout all time, with pre-1010 identical in both? I've found two Compendium theories that work on both.
The dimensions split at 1010 A.D. Does this mean that if two people travelled back in time from either dimensions after 1010 A.D., there'd be two of them in a single dimension?
Probably not. It is suggested that the dimensions are now complete, separate entities. Since dimensions are self-contained universes, Home World simply has the same history as Another up to 1010 A.D., after which it diverges. The Chrono series avoids paradoxes and probably would not create a case where the dimensional split literally happens at a branch on one worldline.
Another World always existed; it is the original dimension, but Home World only extends from 1010 AD onwards. In 1000 AD, Crono exists in Another World. If he travels through time, he can only reach a destination within his own dimension. When Crono defeats Lavos in 1999 AD, or any other time, the battle takes place in Another World.

Sky Dragon Isle Error1) Under the
Time Crash Shift theory, both Chronopolis and Dinopolis work under the same proposed method of time travel (consult the link, I'm not going to explain it). If such were the case, then not only those who enter/leave Chronopolis would experience TTI and TB, but so will everyone who enters/leaves Sky Dragon Isle, as
it is the same as Dinopolis. I haven't fully thought about it, but this could have serious repercussions to the timeline, right? I argue that the "time travel" used by Dinopolis (er, the Entity) is different than that of the Time Crash used by Chronopolis.
