“Game of Thrones” fans are anxiously waiting for Cersei Lannister’s (Lena Headey) walk of shame in Season 5. The scene, which comes straight from author George R.R. Martin’s “A Dance with Dragons” novel, has been talked about since reports of filming were released in early October. With the latest season more than half over -- and Margaery Tyrell (Natalie Dormer) behind bars -- it seems as if the scene is closer than ever.

The HBO series follows Martin’s books pretty closely; however, it also introduces its own twists. The latest scenes involving Margaery and her brother, Loras Tyrell (Finn Jones), differ greatly from the books. On the TV show Loras was arrested for breaking the “Laws of Gods and Men.” At Margaery’s request, King Tommen (Dean-Charles Chapman) tried to release her brother, but Cersei and the High Sparrow (Jonathan Pryce) would not allow it. An inquest in episode 6 found Loras guilty of having relations with a man and lying about it. Margaery was also arrested for perjury after covering for her brother. In the books, Margaery is accused of sleeping with other men, not perjury.

Cersei appeared to get just what she wanted by the end of episode 6. But fortunately Margaery and Tyrell still have someone powerful on their side: their grandmother, Olenna Tyrell (Diana Rigg). TV Guide teases Olenna will do “anything and everything to free them” in the upcoming episodes. However, fans can’t forget she already failed at reasoning with Cersei before the inquest. Olenna went as far as to threaten to cut off King’s Landing from Highgarden’s supply of wheat and barley. But Cersei didn’t flinch. She held her ground, saying she was sure Loras would be freed during the inquest.

Now that Margaery is behind bars, it’s possible Olenna could be connected to Cersei’s upcoming walk of shame. In the books the Queen Mother is arrested for multiple crimes. She confesses to sleeping with her cousin Lancel Lannister, but denies any involvement in the death of the High Septon or King Robert. The Faith Militant shaves her head and forces her to walk naked through the streets of King’s Landing.

According to TV Guide, Olenna -- aka the Queen of Thorns -- “has an ally or two in her debt, and she’s about to call in favors.” It’s possible Lancel (Eugene Simon) could come clean about his previous relationship with Cersei. Or perhaps the High Sparrow already has knowledge of the Queen Mother’s sins. In an interview with Variety earlier this month, Eugene Simon dished the High Sparrow is “actually a very frightening character.”

“He’s so calmly able to convince you of his relatively moderate views on righteousness when actually he’s really dictating the will of the gods,” Simon explained. “And his version of justice is so backwards, in so many ways.”
