Ultimecia's background and motives *SPOILERS*

[Ryushikaze]

The R=U theory has an interesting implication, but A: It's totally unjustified speaking element wise, and B: that implication already exists in the form of the 'Matron' dilemma.

As I was talking with SoS about earlier, I do think you and OK might be taking the phrase 'from beyond time' regarding the witches fought during time compression too literally, especially (if I was reading correctly) the Japanese version said something else there. In any case, even with the original game and its scan info, I've always thought of the Succession of witches as just that, a succession, that you strike down- though not necessarily kill, as Ultimecia controls them when you bleed into their time for brief moments.

I also think that you might technically be overthinking TC's 'mechanics' such as they are. I find a phrase used by the 10th Doctor explains the nature of TC well- 'Wibbly Wobbley ball of Timey-Wimey... stuff'. It's not that all time is a singularity, it's that all time is now touching and infringing on itself, so that time periods bleed through each other and one could 'trip' through time. Incidentally, I think temporal 'bleedthrough' as it were explains the hippie weirdness well enough.

Speaking of the Doctor, I'd describe him as 'from beyond time' too.
