You know the scene I'm referring to.
Well, how about a fic which takes place at any point after that scene (next day, next year, next decade) which involves Lois actually getting one?
Maybe it's a gift. Maybe the story is about the difficulties of getting one. Maybe it's a message for a certain someone. Maybe that message isn't what you'd think. Or maybe it is. Maybe it's not about x-rays. Maybe she's hiding a surprise.
Plenty of possibilities. Where does it lead you?
