I see Dan as more of a realist observing the fluffy, mythical world of Lalande. He is no fawning peasant doffing his cap to the gentry, as in Downton Abbey. I think he gets on with SJ, there's quite a bit of banter between them, but he can see the reality of life there with its problems, and mismanagement, but as he has made it clear, he has signed a non disclosure agreement, now SJ has a following on YouTube and is on a TV programme. They need to keep the fantasy of love and laughter going. The perfect world of Lalande.
I used to, many years ago, work in the gardens of a castle, owned by a couple of aristos fallen on hard times. Death duties swallowed the inheritance. The lady of the house wore charity shop clothes, the husband squeezed into his dead grandfather's suit for occasions, only a couple of rooms were heated in winter. You get the picture. They had gorgeous gardens, and so opened the gardens to the public with cream teas and later a farm shop. The reality was still far from the idyll the public saw, as the house was deathly cold in winter, the revenue paid the bills, but money was tight. There were still the problems of large old buildings to deal with, rodents, water ingress, roof tiles coming off in storms, rising damp, failing radiators, cold and estate staff wages to find every month . Lord knows how they've managed over lockdowns., but at least they had a nice place to be confined in, unlike many poor folk during the pandemic.
I wouldn't want to inherit or buy one of these old places. The house owns you, you don't own the house. Nowhere near as many people would subscribe to a vlog about the reality of Lalande without "the magic" thrown in. I think Stephanie just hit the zietgeist, the pandemic left a lot of people isolated and lacking in hope and joy. She is very personable, enthusiastic, beautiful , good at vlogging, despite the "narcissistic" personality and the manipulation she pulls off, and she made the early vlogs so interesting. Maybe this popularity will recede as the pandemic recedes?
Dan is a pragmatist, he wants his job, but he really needs to keep it now for his YouTube content, as his channel is taking off. He will have a certain loyalty to SJ, if only for his increasing subscribers. His vlogs wouldn't work without the chateau. SJ is smart enough to see how popular Dan and his family are. It helps her vlogs to have him featuring the chateau in his trendy vlogs . They have a symbiotic relationship. He'll be fine.
