Claw of the Conciliator, chapters 26 to 28
Severian finds Dorcas, Dr. Talos, Baldanders, and Jolenta, having been seperated from them after Baldanders' attack. Dr. Talos makes sure Severian is paid for his part in the play, fearful that he has powerful friends. Baldanders refuses to be alone with Severian so he can attempt to heal him with the Claw. Baldanders and Dr.Talos wish to depart alone, and they beat and threaten to kill Jolenta, who wants to go with them. Severian, Dorcas, and Jolenta take the road to Thrax.
Severian is then tempted by an undine, a giant who lives in the water, and hints are made of connections to Baldanders, He comes back when Dorcas calls him- Jolenta was bitten by a blood bat.
One thought really here: Dorcas. She's more alive than before, and acting as Severian's conscience. For example, without her, he'd have freely abandoned Jolenta.
