The Estermonts were her good-kin through Robert, whose father had taken one of them to wife in what must have been a fit of lust or madness. By the time Cersei wed the king, Robert’s lady mother was long dead, though both of her brothers had turned up for the wedding and stayed for half a year. Robert had later insisted on returning the courtesy with a visit to Estermont, a mountainous little island off Cape Wrath. 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, a chunky little widow with breasts as big as melons whose husband and father had both died at Storm’s End during the siege. “Her father was good to me,” Robert told her, “and she and I would play together when the two of us were small.” It did not take him long to start playing with her again. 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.
