Professor Travers' Reactivated Yeti Enforcer

The fully functional Yeti is referenced indirectly as the 'pair of hands' for the Great Intelligence, a direct result of Travers’ experiments with the control sphere. Though not physically present in the scene, its existence is implied as the weaponized outcome of Travers’ scientific curiosity. The Doctor’s deduction that the Intelligence now has a 'ready-made pair of hands' frames the Yeti as an extension of the entity’s will, amplifying the stakes of Travers’ confession. The Yeti’s role as an antagonist tool is critical, as it represents the tangible threat posed by the Intelligence’s return.

The fully functional Yeti is the culmination of Travers’ experiments, described by him as a ‘ready-made pair of hands’ for the Great Intelligence. Though not physically present in the scene, its existence is the linchpin of the confession—Travers admits that his reactivation of the control sphere enabled the Intelligence to seize control of the Yeti, turning it into an instrument of invasion. The Doctor’s reaction to this revelation (implied in his grave tone) highlights the Yeti’s role as the Intelligence’s physical avatar, a tangible threat now loose in London.
