Yay!!!!! But condolences on the 'puter's demise. What a nuisance.
Good luck with the scraping, rummaging around the back of the sofa. etc..
I think unless forced by circumstances she would keep it to herself. I don't think she would trust her brothers or Edwin to "be cool about it". Karl, already an outsider himself, might be a possibility especially if she thought he knew already. William has helped and protected her and I think she would feel obliged to return the favour... not that her inclination wouldn't be that way anyway. I suspect she will be delighted if her instant conviction that Willem is a bit "magical" is confirmed but I won't really find out til I try and write it....
