Okay. Keep your heart rate down, Marillë. Yes, this is the Prince Curufinwe. Yes, he's the most genius Elf in all Aman. But he liked your paper, he asked you to be here. There's nothing to be nervous about.
She knocks on the door.
"Yeah.
It hadn't even occurred to me to ask before you brought it up but do you think it's likely he'll break her heart?"
"Not as long as he's upfront about his feelings, which I'm guessing won't be a problem."
"So that's fine. Of course, I'm plausibly extrapolating way beyond what I have any right to be confident in..."
"He does in fact flirt with people pretty readily. You know your sister better than I but I am not surprised they get along."
"Very well. Should I take a moment to figure out how to summarize it in non-technical detail?"
She does this! She is very enthusiastic about her summary. There is excited gesticulation.
He's good at that. She appreciates it.
Eventually she leaves, trying not to worry too much about their siblings.
All of her clothes go missing one day and turn up with stunningly pretty hot pink lace frills added, three days later, on the clothesline.
...Nice.
She wears the newly-lacy clothes around, and a few days after that his shirts start disappearing and turning up in places Huan's likely to find them embroidered elaborately in multicolored designs with sparkly thread.
This seems like a strict improvement! He plants a bunch of really vibrant fast-growing flower seeds in cobblestone-looking squares of dirt and replaces the ones on her walkway so one day she comes outside to a flower path instead of a stone one.
She picks her way carefully through the flowers and replaces nearly every object in his room with one exactly like it except its chromatic opposite.
