I was totally confused by their video and don't really know what to think at this point. First off, I couldn't hear and understand them very well, thought maybe they'd taken their cues from Selmar for a minute there! But they were all over the place - at one point saying if they don't get a good price - they won't sell, they could change their minds next week - and they won't sell, someone needs to run the business and it's too draining to go back and forth (and I get it...it would be a huge hassle!), so they have to sell. And as you pointed out, Carole saying "we need to sell". I thought I heard Adriane say he's putting in a new boiler as well as taken in a huge load of drywall, so he said they'll still be working on the chateau ....but if it's such a draining thing to go back and forth from UK to France, why bother and just sell it "as is" right now?
I don't know if it's because they are just so conflicted by needing to make the decision they've made, I just know that as I watched them, I felt incredibly sad for them, as this was a dream of theirs and, for whatever reason, it has died.
