I never mentioned that Ranma accepted Cologne-- on the contrary, I
have him trying to find some middle ground between the polar opposites
of Cologne and Happousai. The time of day, twilight, between day and
night, light and dark, serves to highlight this search for balance.
	The way I see it, there are three possible stories here 1) the
obvious one is that Ranma accepts Cologne's proposal, and eventually
attains the 'soul of ice.'
2) Ranma stays with Happousai (perhaps after hearing Happi's story, or
for other reasons)
3) Ranma's search for his own way, not necessaricly based on either
Cologne's, Happousai's, or some combination of the two's, philosophy,
training, or style.

	Ah yes so Cologne is the Vorlon's, Happousai is the Shadows, and 
Ranma is Sheridan
