Mary asks the king and queen for permission to talk to Colin. Catherine wants to know why, and then when Mary bumbles around to saying she might have sent the wrong message with her excitement at the wedding, Catherine cautions her about letting gossips have anything to talk about. The king says Mary may have behaved foolishly, but she's not responsible for what Colin did. Ah, sixteenth-century slut shaming!
Mary insists that Colin is her subject, as we see guards marching to his cell. Henry replies that there were witnesses who implicated Colin in an English plot to destroy Mary's engagement to Francis, and Catherine expositions that if Colin had raped her, she'd be unfit to marry a royal. "This was not passion. It was treason," she says, relishing every word. Guards drag Colin out of his cell and chop his head off. (More foreshadowing!) Henry tells Mary as much.
Mary tells Lola, who's sadder than that time SWINTON killed Aslan in front of her. Lola shrieks that Mary's the reason Colin's dead, and says everyone around her is disposable, in danger. Mary insists that the girls are her friends and she needs them, but Lola cries that the other three are her friends, but they're Mary's subjects. Mary swears to protect them.
Stirling! Bash has found Stirling and brought him home. Mary cries and hugs the dog, and Bash tells her she's not alone. And he's not talking about the girls. But then he sees his mother watching and get formal in a hurry. He wishes her well. She thanks him. Diane plots. After Mary leaves, Diane asks Sebastian where he found the dog. "It was drawn to the blood," he says. She tells him to be careful who he lusts after, especially when she's a queen betrothed to someone else. It might cost him his head.
Mary's looking out over the water in the morning. Francis asks her what was up with her defending Colin, and thinks she was trying to get back at him for his dalliance. Mary can't believe he'd be such a petty little shit, and tells him to fuck right off. He cautions her about her behavior, and she asks why it matters since he doesn't plan to marry her. She threatens to tell everyone and end their sham engagement.
Francis insists that he might still marry her, because he's such a noble little larva, and she's not thrilled with that. He asks if she was thinking of Scotland during the Colin Incident, and she says she was trying to keep herself and her friends safe. He shames her some more for the crime of having someone break into her room and try to assault her, and tells her she could have ruined their plan. Mary seizes on the word "we" and asks what their mutual interest might be. She asks if he'd want her if they were normal, non-royal people. He leans in and then chickens out and flees.
