It’s "The Last Joust" for King Henri in 'The Serpent Queen'

Episode 6, “The Last Joust,” of The Serpent Queen opens with an ominous, twisted fantasy. An injured King Henri is carried on a bier by Montmorency and Francois. The processional is followed by Catherine and Diane, walking hand in hand. The two women turn to each other; the series seems to suggest the two are going to kiss, but then the image fades, and we see Diane fall from a high castle window. (Sorry, it’s not real.) The scene changes as Catherine sits beside her husband. Blood trickles from under his bandages, but it’s not blood, but something else moving, turning into a snake that bites her. When she looks at Henri again, the bedsheets have turned him into a marble effigy.

Diane: I’ve always hated church bells. Either someone’s getting married or someone’s dead. Either way, a soul is lost.

Back in present-day reality, Catherine visits Rahima, imprisoned after being caught in Mary’s chamber. Despite Rahima’s being there on Catherine’s orders, the Queen proceeds to thoroughly gaslight her. Whatever was Rahima doing there? Catherine didn’t ask her to do anything of the sort!
