It is the man that eventually comes to visit after what seems like a long time.
He does not say much, neither does he stay long, but what he does is deliver a parting gift: a new sketchpad, and a box of coloring pencils.
And while he is no longer there, she is finally put to use. She sees more of the man, and more of the others that she knew he and the man were colleagues with...or comrades.
The Organization XIII, all people without hearts.
At last, she meets the one in her pictures, and just as she had to let him go, she lets this one go, too.
They have a long road ahead of them, but their path is not one she can follow.
All she can do now, is wait.
When she sees him again, he does not seem to remember her, but for a moment, she does not let it bother her.
For at last, he is smiling like he never smiled before, just as he has never seemed this happy before. At last, he has the peace he never had before, without his memory - or loss of it - to distress him. At last, he is the child he didn't let himself be before, and she sees it all.
But that brief moment cannot last, for even though he is happy, he has to know the truth. And even though the truth hurts, she has to be the one to tell him.
And when the time comes that, she once again lets him go, to reclaim the destiny he could not remember.
Even in those moments of sadness, of meetings and farewells, she holds on to the words of that day.
"We'll see each other again...it's a promise."
And so, she waits.
