This is a little... disjointed, sorry. The quotes are from Advent Children, by various characters, and don't really have any significance other than they reflect what Aerith is thinking.

She wanted him to be happy ...you're alright now?
He'd come back from wherever he'd disappeared to with him ...the nightmare.
He seemed lighter ...I think my burden has lightened.
But not quite complete ...it's okay to die. Is that what you think?
She wanted him to be happy ...more than anything.
She wanted her to come back ...you were there for him all along, weren't you?
For his sake ...I'm not alone.
And for her own ...we can help each other.
For all their sakes ...there's not a thing I don't cherish.
She would come back ...I guess they must be fond of you.
She had faith it that ...no giving up!
