The story begins when Táíwò fails to show up for their crucial meeting at the water tank. When they investigate his rooftop location, they find his carefully drawn chalk map smeared with tire marks from helicopter rotors, indicating he was taken by special forces rather than ordinary police.

As specified in your prompt, Aṣàkẹ́ narrates how she had seen CCTV footage earlier of someone in a hoodie whose clothing was "flapping in the wind" as they scouted their area. They find a torn piece of hoodie fabric on the rooftop, suggesting this person was present during Táíwò's capture.

The most shocking discovery is the single teal strand caught on barbed wire - the same color as Rírì's distinctive hair, but not from Rírì herself. This leads to the horrifying realization that someone has been impersonating their group members, dyeing their hair to match their resistance symbols and infiltrating their network as an informant.

The chapter ends with the understanding that they're not just fighting government surveillance, but also betrayal from within - someone who looks like them, knows their secrets, and has been feeding information to their enemies. The teal strand becomes a symbol of how their own resistance markers have been weaponized against them.
