She also mentioned, if I understood correctly, that the next episode will be behind a pay wall.
I understood that too.
Has anyone heard any rumours about that - that "Brigitte" might be Macron´s father?
Yes. If you want to read something about this, you can do to this page:These are assumptions based on the resemblance between Emmanuel Macron and the son of "Brigitte Macron", Jean-Jacques Trognieux, which leads one to wonder if they are not half-brothers.
and translate what is above and under the same picture you saw on X.
It really is a mess, and I can't even keep all the facts straight. But basically, nobody really knows who Macron's father was (most likely not the man who was said to be his father), and Macron's mother was a very good "friend" of "Brigitte". There was also a priest involved, who used to encourage people to transition and such. He is another possible father.
At this point, I wouldn't put it past these sick people for the story of Brigitte being Macron's biological father being true. But I THINK that Xavier Poussard had some argument against it already, though I can't remember for sure.
