The dank and dismal fortnight Cersei spent at Greenstone, the seat of House Estermont, was the longest of her young life. Jaime dubbed the castle “Greenshit” at first sight, and soon had Cersei doing it too. Elsewise she passed her days watching her royal husband hawk, hunt, and drink with his uncles, and bludgeon various male cousins senseless in Greenshit’s yard. There had been a female cousin too […] As soon as Cersei closed her eyes, the king would steal off to console the poor lonely creature. One night she had Jaime follow him, to confirm her suspicions. When her brother returned he asked her if she wanted Robert dead. “No,” she had replied, “I want him horned.” She liked to think that was the night when Joffrey was conceived.
