It did seem to me that it happened rather...sudden and out of the blue that he went from not being able to stand her to OH MY GOD MUST SAVE AND PROTECT, but then, it happened in an instance where it was a "you don't know what you have till it's gone" situation...so I still think it was well done.

But yeah, I'm sure he was dating Quistis and she was dating some dude from Deling City by the next year.
