When Margaery arrives in season 2 with her complex love triangle with King Renly (who is in love with her brother Loras), we are treated to a new Cersei-level relationship clusterf*ck. This one is quite nasty as well because she brings her brother into bed with her in order for her husband to "get it up" so she can try to get pregnant. In season 3 she acts more of a lady, making it easier to see Natalie Dormer's true beauty shine through. That said, Rush treats you to her sexy side, and the movie is quite brilliant to boot.
