'You don't know what she is.' the druid says, referring to Ciri. The double stabs the real Mousesack, slowly, seeming to enjoy it. The doppler tells him that every experience he's ever had, every thought, is now in his head. His eyes whiten and his skin distorts, and suddenly he's the exact double of Mousesack. Mousesack makes a run for it, but the doppler chases him, pins him to the ground. 'This one?' the shapeshifter says, disappointed. Mousesack, royal advisor to the Cintran royal family, is dumped out of a Nilfgaardian wagon. Cahir offers the man, who refers to himself as We, a job-to assassinate someone on behalf of Nilfgaard. The man in the mirror is a doppler, a kind of shapeshifter who, in their natural form, are hideous, lumpen monsters. Then a shadowy figure appears: it's Cahir, the Nilfgaardian soldier who has been hunting for Ciri. He looks at himself in the mirror and smiles, dropping his cloak, admiring his body. Embalming fluid, perhaps? He places the jar on a shelf with many others containing other body parts, including an ear. A man inserts a piece of flesh into a jar of strange liquid.
