I will say that she's basically a nice person. She helps Cloud in the hospital and the Lifestream which is something.

She isn't strong in terms of emphatically confessing her love for Cloud either and even at the end they don't really feel like a proper couple.

I heard Squaresoft cut a scene where it showed them coming out of the airship's Chocobo Stable, which implied....coitus :-D

But Square cut it and we are left with a weak lovestory as well as a weak Tifa.
