"Lilypad, what do you want to be when you grow up?"

It is halfway a joke, something passed around by the adults at Sunday dinner. Because Lily Luna and grown up go together like Weasley hair and Slytherin. This baby of the family with dragon dreams, glitter falling from her curls and adorning her cheeks, she could could never grow up.
Predictably, she chooses a child's answer: Lily Luna is going to be a dragon tamer, thank you very much. The only one to take her seriously, to read to her from his old Care of Magical creatures textbook and get her parents to talk to Uncle Charlie about visits when she's older, is the calm boy with ocean hair who stays closer to the petite redhead than her glitter.

And then comes Hogwarts, and it seems at first that Lily will never grow up. The glitter stays, joined by short skirts and deadly heels that just barely make the dress code, and most importantly, a Slytherin tie.

(it turns out that Weasley hair and Slytherin can get uncomfortably close)

But seventh year something changes. An invitation arrives, dripping glitter and lace, proclaiming that the boy with ocean hair and the girl with veela eyes are getting married.
(He'll have no more time for silly little girls with glitter in their curls and dragons in their eyes, is what it means.) So Lily Luna grows up, quite suddenly. She brushes the glitter from her hair just in time for the old question to resurface.

"What will you do after school, Miss Potter?"

The answer she gives is the one that is expected of her, of the new-and-improved Lily Luna. She'll be a Healer then, isn't that nice and grown up?

(And maybe she'll learn how to fix her heart, because it seems to be a tiny bit broken)

So she signs up for Healing school and yes, of course she'll be a bridesmaid, if that's what Victoire wants.

(Named for victory, she'll get what she wants anyhow, no sense in fighting)

Yet on the day of the wedding, as she stands where she's directed Lily can feel the little girl with glitter in her curls fighting to get out, yelling at her to

runrunrun

So she does.

And when Lily Luna grew up, she became a dragon tamer.
