She was in a cage and had formerly housed Lola while pregnant, Estelle. Narcisse introduces her as his bridge. Hands shaking, she gives Lola a gift. Inside is a note, "help me." Yikes.
Mary is talking about propelling a child to walk on the hills where she and Francis played as children then announces she is with child. They are soon taking another tumble in bed. He wonders how she kept it a secret so long. She didn't want it to interfere with the coronation or the christening.
In pops Catherine! Stay back! Screams Francis. But grandmama knows. She has had her eye on Mary and she's super excited. This makes Mary an heir bearing Catholic and strengthens their claim to the English throne. Catherine has an entire menagerie of stuff brought including food and sage to ward off spirits.
Mary shares the news with her friends and they have champagne. Lola wants to marry again because it's the only way women can have any standing, lands, money.

Kenna shares about her happy marriage of passion with Greer while she tries to get Greet to admit she is ruled by desire even more than Kenna and she might as well just admit it and be happy.

She has just killed a guard. Mary decides to help. She claims her servants are transporting Henry's heart to the basilica.
Mary and Lola mend their friendship and Lola asks her to be godmother. Francis is utterly pleased. On her way to the christening, Mary starts to suffer a miscarriage. Conde happens upon her and helps her to her room. There is blood on her shoes. She doesn't want to ruin the christening and won't tell anyone until after. Conde is concerned.

Lola finds Narcisse rubbing the hair of Estelle's dead body. He doesn't understand how she got away. Lola says Estelle seemed troubled. Narcisse shares that Estelle's father owed her a great debt. They got married so she could keep her lands and because he needs an heir. He explains his other wives to Lola. The first miscarried so many times because his father pushed for an heir. His second wife was a hemophiliac and died before his eyes.
The shepherd has killed his wife and children. He thinks he was possessed. He said no, but he got the mark anyway and they took his soul and let the devil in.
Mary is in bed. She's pale. She tells Francis and he wonders why she didn't send for him. Mary wanted him to be happy and she has spent so much time wondering what their child would look like and she starts sobbing while being cradled by Francis.
Greer refuses to leave Castleroy. She knows who he is rather than wondering what kind of man he will become. Greer wants to see what's really between us. She seduces Castleroy.
