The reason for the open ending with the ambiguous "and..." is readily apparent if you merely glance at what she says just before that: "Time, it will not wait". The fact that Ultimecia never finishes her sentence is meant to drive this point home, although most people don't really notice this obvious purpose. That's all there is to it; no secret information being snuffed from us or anything.
Anyway, I personally see it as Ultimecia talking about fate, and how they cannot escape it no matter how hard they try (this was essentially the lesson she learned by being defeated by Squall after all). But yeah, she could be talking about a whole lot of things... |
