On last week's Game of Thrones, the High Sparrow (Jonathan Pryce) swooped down and plucked two roses from House Tyrell. Ser Loras (Finn Jones), aka The Knight of Flowers, was charged with having sexual relations with another man — a crime in the Faith of the Seven — and his sister Queen Margaery (Natalie Dormer) was also arrested after lying under oath.

But as the two siblings are sitting in their jail cells, we'll soon find out that they haven't been abandoned. Their grandmother Olenna Tyrell (Diana Rigg) will do anything and everything to free them. After all, she was the one who actually put the poison in Joffrey's wine at his wedding, so that Margaery wouldn't have to live with that monster. The so-called Queen of Thorns still has an ally or two in her debt, and she's about to call in favors.

She'll have to act fast though. Although it's clear that Queen Mother Cersei (Lena Headey) had a hand in laying the trap to discredit them, the High Sparrow has proven to be more powerful and wily than his kindly demeanor would have you believe. "We don't know how much the High Sparrow already knows," Eugene Simon, who plays newly initiated Sparrow Lancel, tells TVGuide.com. "That is the nature of his intimidation genius. I think that the High Sparrow has kept his cards very close to his chest. I always believed that the High Sparrow knew, almost from the very beginning, what exactly [everyone] has gotten up to because he would never be able to have as much control if he didn't."
