Lollys Stokeworth is a member of House Stokeworth, a noble family of the Crownlands, and the second daughter of Lady Tanda Stokeworth. She is considered dim-witted by Tyrion Lannister.
Cersei Lannister arranges for a marriage between Lollys and Ser Bronn of the Blackwater, to sway the ambitious ex-sellsword from Tyrion Lannister's service. Though her older sister, Falyse, is heir to Castle Stokeworth, she is forty years old and barren, and Bronn suggests to Tyrion that she may suffer an "accident" in time, making Lollys the sole heir.
Lollys is enjoying a walk with her betrothed, Ser Bronn, outside of Castle Stokeworth while discussing their upcoming wedding. She also confesses to Bronn how her sister Falyse is mean to her and will not let the couple live at Stokeworth when their mother dies. Bronn comforts Lollys, believing that mean people will always get what they deserve. The two are interrupted by Jaime Lannister, who intends to recruit Bronn on a mission to Dorne in exchange for a better wife and castle, since Cersei Lannister has broken her agreement with Bronn and Lollys will instead marry Ser Willas Bracken.
Cersei arranged an engagement between Lady Stokeworth and Ser Bronn of the Blackwater to keep him from fighting on Tyrion Lannister's behalf in Tyrion's trial by combat. The engagement was broken when Jaime Lannister recruited the knight for his secret mission to Dorne.
