[Tifa catches her breath. Now that is a loaded question. Possibly the most difficult question Aerith could have asked. It's something she's avoided confronting herself, because does it really matter? The important thing is what needs to be done to fix this mess and save her family, and in the meantime she's just trying to keep them as safe and happy as possible.

So she looks away again, then shrugs.]

It's been two years. I've had the chance to see people I never thought I'd see again... Make friends I never would have met. I've... made a home here in Luca. It'd be easier to settle down if people weren't always coming and going.

You've disappeared and come back so many times, Aerith. So has Cloud, and Zack. Almost every time you forget that you were here, you're a little further behind than I am. Nothing's constant. That's the hardest thing.

[She's... probably permanently damaged by all this. Not that she sounds upset exactly. It's just the way things are.]
