On a serious note I would say that there maybe something not ok mentally. He’s working in a foreign country, that speaks a different language from that of his birth. So he may not have the words to convey how he feels. In addition he lost his Dad, did he not? That’s a lot to deal with a s a relatively young man. I have lived and worked overseas it’s difficult to be separated from your family at times and I had the big blue blanket of the RAF to support me.
It could be that it’s better all round if he goes home to France. Pity, because when he was on song he was magical!
