Other mistake: When Centauri "dies", he had a smile when stopped moving. After Grig closes Centauri's eyes, not only is the smile gone, but you see his now-closed right eye flinch after Grig's hand is gone.
Suggested correction: As the entry itself notes by putting "dies" in quotation marks, Centauri is not really dead. His body simply shut down to repair itself, which means it is still operating on some level, which allows for the possibility of small movements as described.
