Unlike many of the other Carnival workers, 9S is still unchanged, his appearance still human-like save for his legs; his synthetic flesh has melted off the back of his knees and sides of his calves and thighs, exposing his metal frame. As usual, Pod 153 hovers not far from his shoulder and his eyes are covered by his visor.

So it might be strange that he's seemingly following her gaze towards the 'swan' and also tilting his head. Sorry, he's not seeing it. But that's mostly because....

"What's a swan?"
