Object
Doctor's Handkerchief (Used to Block Gas Nozzle)
A plain cloth carried by the Doctor, the handkerchief holds no power of its own, acting purely as a vessel for his resourcefulness. It was first thrust into a gas nozzle inside the Chameleon Tours hangar to foil Spencer's trap. Later, its role shifted to healing: dipped in water to cool Sorba's shoulder in a dark mine shaft, and offered to Zoe to bind Thara's fractured leg. Its final known use was as an improvised anemometer; held to an air conditioning grille in Stewart's office, the faint stirring of the fabric provided the crucial proof that power remained for their desperate attempt to restart the TARDIS. The handkerchief thus traces an arc from blunt instrument to tender bandage to quiet scientific confirmation, embodying the Doctor's own adaptive genius across vastly different circumstances.
