Chaol and Dorian enter the castle through the kennels, apparently to avoid Hollin who has returned that morning and is shrieking demands at everyone. Dorian reveals that there is a court dinner being held in Hollin's honor, which he wishes he could avoid, and that their mother pulled Hollin out of school due to the King wanting to keep him close while the movement against him is resolved.
That night Hollin attends the court dinner and is seated on a little glass throne beside Dorian. The singer Rena Goldsmith performs, and though her singing is beautiful Hollin begins squirming beside Dorian and hissing, complaining about being bored. He doesn't appear to like the performance.
