3. Olenna Tyrell, "The Queen of Thorns"
If the Tyrell matriarch wants her cheese now, you better believe she'll get her cheese now. Olenna Tyrell (Diana Rigg) doesn't take crap from anyone in the Seven Kingdoms and she'll always be around to tell it like it is. The Dowager Countess of Westeros is a scene-stealer and many of her scenes were smartly invented for the show. Some of her best one-liners? "And when a Tyrell farts it smells like a rose." "I always take figs mid-afternoon. They help move the bowels." "Old." - her thoughts on Cersei "A sword-swallower through and through." - on her grandson Loras This lady even stands her own against Tywin Lannister when he threatens to name Loras to the Kingsguard if he doesn't marry Cersei. Even when she loses an argument she manages to get the last laugh. Who else has replayed the moment where she snaps Tywin's pen about a dozen times?
