Belle studies. She really doesn't get as lonely as Beast - and maybe he and Chelise can fall in love if she stays out of their way, and then the curse will break and Belle can ransack the library and go home, that would be fine. She works.
"Yes," Charlie acknowledges. "How are you going to go about retrieving your title? Can you prove your identity if you can't remember your name?" he asks Beast.
"And I suppose casting spells at the problem won't help, since I've an obvious motivation to wish you declared a marquis," Belle muses. "Oh well. The forest is largely unclaimed anyway. We can live in a castle and not be marquis and marquise, or at least not acknowledged as such by the Crown."
"...I suppose you may."
Charlie looks vaguely suspicious about this phrasing.
Charlie nods, mouth a thinning line. "Sounds past time."
"Is it, now."
"Yes," says Belle.
Charlie chews his lip, then settles his arm around Belle's shoulders and heads for the door.
The church is a small affair, and the priest is in fact prepared to perform a wedding right then if they want to. Belle looks inquiringly at the Beast.
The wedding is fairly summary, with Beast's name given as Jean of no last name who'll be taking 'Cygne' as his surname, and Charlie and the priest are the only witnesses. Charlie cries and pretends not to. Belle looks fondly at her father, and then properly beams at Beast, and kisses him when the time is correct.
Belle isn't really paying attention to him. She's busy kissing her new husband.
Then he murmurs in her ear, "Your papa is crying."
And presently, "Let's go home and start looking through books, shall we?"
Eventually she has her supply of magic books extracted. Including those that are in foreign languages. "You can read again without hurting your eyes, I assume," she observes.
Belle hands him one of the foreign language books that they never got around to categorizing, and then consults her index for which of the categorized books is most likely to contain castle-building instructions.
Eventually Belle finds something. "Here we are," she says. "I think if I do this right, I can even get it to organize the library in the process. I do need to design the layout, though, and decide what it should look like."
