Send me a symbol and I’ll tell you the difference between AU and Canon. Then I’ll tell you which one is better.

For the purposes of this question I’m going to go with Aqua/Terra in terms of canon considering that’s what’s going on here in FRW, but I realize they are in no way 100% canon in-game even though I like to believe so 99.9% of the time, it is in this .1% that I am making this disclaimer.
In canon neither of them are really uh, doing well right now, Aqua’s been stuck in the Dark Realm for twelve years and Terra has been possessed and controlled by Xehanort for the same amount of time so... Yeah! Things are super awful but I could only imagine-- and hope-- that there’s hope for them in that Aqua will be rescued and Terra will be un-norted and they can have a really adorable reunion. Before all of that junk happened though... I think there were feelings that were unspoken, they weren’t together together y’know what I’m sayin’.
In AU the circumstances... are less horrible! [confetti] but still horrible sometimes because Terra seems to have a penchant for trouble no matter what universe he’s in. Aqua has feelings but is too dense to notice and would really, really appreciate it if Terra stopped coming back home with the shit beat out of him. Things will probably work out eventually though! Probably.
I’d also just like to say here it’s clear that while Aqua has had no prior romantic experiences in canon she’s probably??? (???) Had at least one short fling in middle or high school or something in this AU that ended quickly because she’s no fun at all.
In canon, Aqua’s future plans include:
Getting out of the Realm of Darkness
Waking up Ven and saving Terra
In AU, Aqua plans to... graduate college, and she’s still not quite sure what she wants to do yet! While it’d be fun to travel she also doesn’t want to leave her sister or her friends behind. Her plans are less concrete but also less dire so... I don’t know what constitutes as better.
