[*]I'm still not quite sure how the age thing gave the whole switch away.
This shot of the Psalm of the King clearly gives Louis year of birth as 1710, the proper and historical date. So I really don't get how Lia deduced from that the whole secret. Maximilien's date of birth is given as 1700 which makes little sense given his age in the series but I don't see how that shows he's the real king.
-I have no idea what was the purpose of sudden revival of Saint-Germain. It only brought more confusion to the final confrontation.
-The powers of Poets and of the Psalm of the Kings, as well the connection between them were kept as vague as possible. Where did the latter come from ? Why was the Versailles the supposed source of Psalms ?
-On that note Robespierre survived getting killed by Dashwood but it only took single stab from Broglie to do him in.
-If Louis XV wasn't of the royal blood then how was he able to lift and flip the pages of the Psalm ?
-Why would Louis XV of all people dispatch 3 men with close ties to Lia on a mission to find her murderer ?
-The motivations behind Teillagory's betrayal and Robin's sudden 180 flip are weak. <Rant> Louis XIV left France in worse state than his successor, he conducted more pointless wars and in his youth was as big a womaniser as his great-grandson. So to betray D'Eon just because Louis XV is supposedly bad king makes no sense.</Rant> As for Robin he takes on the name and cause of murderer of Durand after a very short time spend together with him. I get that Marie's death was big shock but it felt completely unbelievable. Especially since he ended up contributing to her son's/grandson's death.
-Belle served no meaningful purpose.
-The palace security still sucks. Seriously.
