Thought:
1. The whole point of my post was to make the connection and show that both games exhibit the same "paradox", if people still choose to call it that. I suppose one could get away with saying that "Ayla" might not be the CT Ayla, but either way is stretching something.
2. I'm assuming that the Chrono Cross put everyone in their proper place in the "Ideal" timeline. Or, perhaps, the "land anger" was connected to the Chronopolis stuff somehow, which then ceased to exist.
3. Lucca almost DEFINITELY existed in Home World, as basic arithmetic with people's ages implies that Kid was found BEFORE Serge was bitten. One could argue that the dimensions actually split before then, or that Kid rewound significantly enough to mess up her age (not likely), I guess.
But do we actually know that no humans existed in the later Reptite timeline? I mean, it's a bit of a stretch but there COULD be...
Well, we could count the Green Ambler as well as his counterpart in the Reptite ending of Trigger.
