A Feast for Crows
Jocelyn is present when Dowager Queen Cersei Lannister receives news of Tywin Lannister's death. She attends the wedding of King Tommen I Baratheon to Lady Margaery Tyrell. Jocelyn throws up when Cersei is presented a dwarf's head covered with maggots whose killers pretend to be the head of Tyrion Lannister. Jocelyn spends time in the queen's apartments with Lady Taena Merryweather and Dorcas while Cersei is away for a small council meeting.
