^Disagreed.
Nothing Squall ever said or thought even slightly pointed to him being head over heels in love with Rinoa. It literally goes like this.
Beginning of disc 1: This girl is hot, let's dance.
Most of disc 1: This girl is nothing but an annoying burden.
Disc 2: She's annoying, but ok I guess.
The VERY end of disc 2: Why should I waste my time saving her? I have other priorities. She's no more important than any of the others. You do it Zell.
The VERY beginning of disc 3: I CAN'T LIVE WITHOUT HER!!!!!!!!!! I'D DIE FOR HER IN AN INSTANT!!!!!!!!!!!
Me: No... just no.
The Orphanage Twist wasn't foreshadowed either. Hell, the GFs causing memory loss was just a convenient Deus Ex Machina to cover up the fact that it's never foreshadowed. Notice how the memory loss thing is never brought up before or after this "twist" is revealed. Not to mention, that they don't even really cause memory loss. It's like their memories(of that single thing) were placed into a folder, and all immediately come back once Irvine brings this up.
It was just poorly written any way you look at it.
