Exposing and Capturing Milling's Fly-Shapeshifter Spy

Exposing and Capturing Milling's Fly-Shapeshifter Spy is the moment Carag recognizes that the surveillance around Clearwater High has reached into the smallest and most easily overlooked forms of life. Recovering in the infirmary, he notices a woodwalker where others might see only a fly; his warning brings the school’s staff together to trap and identify an infiltrator connected to Andrew Milling. The capture confirms that the threat is real, but the spy’s silence and release leave the larger network unresolved.

The Clue in the Infirmary

Carag has been left alone to rest after the school’s end-of-year exams, and Bridger has just gone. Even in the quiet, Carag senses that another woodwalker is in the room. His instinct, sharpened during his months at school, tells him the presence is exceptionally small. He briefly considers Juanita or a second-year student who can become an ant, but neither guess explains why a woodwalker would be there.

The overlooked clue is the fly circling the lamp. Carag recalls that flies often gather around Brandon’s head, as they do around ungulates generally, and recognizes that their familiarity has made him stop noticing them. Because other woodwalkers are usually nearby, he has also failed to distinguish the fly’s presence as a separate shapeshifter. He now suspects that it has been watching him and passing information to Milling: Carag and Brandon spend a great deal of time together, giving an observer near Brandon repeated opportunities to learn about Carag. The inference is plausible rather than certain, but it shifts suspicion away from Brandon himself. Carag concludes that Brandon was not the one betraying him; the spy was one of the flies that accompanied him.

Trapping the Intruder

Carag does not confront the fly by trying to catch it himself. He gets up as though he is going to the sink, changes direction at the last moment, and runs to shut the window. The fly panics and buzzes around the room, searching unsuccessfully for an exit. Carag calls for Bridger and Sherri Rivergirl, then urges them to close the door and warns them that the fly may be a spy.

The adults respond without laughing at him or dismissing the warning. Bridger studies the insect, focuses on it, and confirms that it is a woodwalker. He believes the shapeshifter is male and establishes a crucial distinction: the intruder does not belong to Clearwater High. Bridger goes to summon Lissa Clearwater and Bill Brighteye in case they need reinforcements. Meanwhile, the fly tries to escape when the door opens, fails, and retreats to a corner behind the lamp. Lissa blocks its exit by spreading a blanket on the floor and orders it to transform, making clear that she will otherwise take further measures.

Identification and Interrogation

The fly eventually transforms into a young man, pale and rather thin, who is wrapped in the blanket and regards those around him with contempt. Brighteye questions him about why he is there and who sent him. The man refuses to cooperate, as Carag had expected. His appearance establishes that the fly was not merely an animal in the room but a shapeshifter operating inside the school under an assumed form; his refusal, however, prevents the immediate identification of his employer or purpose through questioning.

Bridger, Brighteye, and Lissa try throughout the night to obtain information. They photograph the intruder and take his fingerprints, preserving identifying evidence even though the interrogation yields no confession. Lissa considers the practical limits of keeping him captive: the school cannot simply hold him indefinitely, and handing him to the police as an intruder would risk giving a shapeshifter an opportunity to fly away. After the overnight questioning and documentation, the staff let him go. The episode therefore produces an exposure and a record, not a secure arrest or a revealed identity.

What the Capture Leaves Unsettled

Carag’s discovery also reopens an earlier, unexplained sign of surveillance. He remembers that on his first night at school, when Brandon transformed in his sleep, something passed in front of the window. He wonders whether it might have been a messenger carrying information to Milling from the flies. That recollection does not prove that another spy was present, just as the captured man’s relationship to the whole network remains unknown. Carag and the others cannot tell whether they have exposed Milling’s principal spy or only one among many.

The scene turns on a contrast between concealment and perception. The intruder’s disguise works partly because a fly is ordinarily easy to ignore, and because Carag has grown accustomed to seeing flies around Brandon. Yet the same small, familiar detail becomes evidence once Carag’s developing instinct makes him question what he had ceased to notice. The capture validates his alertness and shows that the school’s danger is not limited to open confrontations: information can be gathered from within, in plain sight. But the spy’s release leaves the surveillance problem alive, with the school having identified one infiltrator without knowing how many others may remain.
