She thinks Jaime is coming;
- Loras the flower knight, Margaery's brother, is wounded on Dragonstone (has he woken any dragons?);
- Osney Kettleblack has been tortured into spilling all Cersei's secrets;
- Admiral Aurane Waters has buggered off with all the ships (what is he doing with them?);
- Harys Swift, Grand Maester Pycelle and Kevan Lannister are running the realm;
- The Merryweathers, including Cersei's friend (of dubious loyalty, imo) Taena have buggered off home;
- Cousin Lancel has betrayed her.
She's locked up and deprived of sleep by the septon until she confesses. She manages to confess to only a few of her crimes. Seems the septon knows everything (her children are Jaime's, she plotted to kill Robert, she plotted to kill Margaery, she had the previous high septon bumped off. Cersei makes excuses for some of it and denies the rest. The septon doesn't care but says she will face trial. He lets her choose visitors.
Kevan Lannister visits her and brings her up to speed on Jaime, who has disappeared with Brienne (to be murdered by Catelyn's men?), Stannis (who is presumed to have hired the sellswords who are landing), and Myrcella (who is missing an ear). Cersei is still obsessed with blaming everything on Tyrion and the Tyrells and ignoring real threats like Stannis. Kevan also talks about sellswords from a free company landing all over the south and wonders where Stannis got the money from. Possibly from Tycho Nestoris I suppose, although it seems too quick for that.
Looks like Cersei is going for a trial by combat, and so she has asked Qyburn to choose a kingsguard replacement for Ser Arys. Which presumably means the Frankenstein's monster he's been cooking up out of GREGOR's body parts or whatever it is.
