I apologise if people find my interpretation of Aerith more than a little angsty, hopefully it will be explained in the end.

Aerith.
Meagre: deficient in quantity or quality; lacking fullness or richness; scanty; inadequate.
She'd always tried to help them.
Having lost someone herself, she knew what it was like to have your world crumble around you.
She'd never been trying to replace the ones they'd lost.
In the end, all she'd wanted was to make them happy.
But she wasn't enough for that.
She chided them, she made them eat, made them sleep.
She asked them how they were; made sure they talked, even if was just a little.
But it wasn't enough, she wasn't enough.
Rinoa… Tifa… when they'd gone, they'd taken a little bit of Leon and Cloud with them.
And her attempts to fill the gaps were meagre at best.
