The fist tightened. No would not do; Yes was worse; Cam had told her to pretend to be the Captain. Nona decided to pretend to be the Captain, and opened her mouth, and screamed like the Captain had screamed.
She had never been good at coming up with conversations. Nona simply made her mouth go as the Captain’s had gone—she could remember the movement, it was easy—and she screamed, “Help! Help! Help!” for want of anything better to say.
The scream moved through her chest and up her throat and out of her nose. When she let it out, it did not at all sound like when she had heard the Captain do it. The scream somehow seemed to take all the lining of her throat with it. It was like the scream was made of her insides—her insides dissolved and resolved themselves by coming out her lips as a vocal bomb. The electric light sizzled in its housing. The room went dark. Prince Ianthe Naberius dropped her and staggered back, and Nona completed her Captain impression by pitching forward, onto the carpet, facedown, practically senseless, aware of nothing but the scream—a noise that seemed to keep coming out of her nose and ears and mouth. She went away from herself briefly.
