*** There is an overarching plot line that did not totally make it into Chrono
Cross. It suggested that if Serge did not stop the Time Devourer, he would
inevitably merge with it too, and that this would complete the being and result
in the death of spacetime. Lynx's calling him the "Assassin of Time" is very
suited for describing this outcome. For more on this plot line, read:

Ideal Timeline

-The dimensions merge, perhaps creating an ideal dimension. Serge lives.
