The Homing Device Threat Exposed

The Doctor and Anne examine Professor Travers’ control sphere and its companion box, only to discover its critical limitation: it cannot override the Great Intelligence’s commands. Their analysis is abruptly interrupted when Evans delivers a reprogrammed model Yeti—a homing device that lured the Yeti to the explosives store. The Doctor’s realization that this device is actively broadcasting their location escalates the immediate threat, while Anne’s revelation that the other Yeti models have vanished heightens suspicion toward Evans. The Doctor’s urgent demand to dismantle the homing device underscores the ticking clock of the Intelligence’s coordinated attack, as Evans’s defensive posture and insistence on retrieving his tobacco tin (containing the stolen tunnel fungus) further implicate him as a potential traitor. The scene pivots from technical assessment to a crisis of trust and escalating danger, forcing the Doctor to act decisively before the Intelligence’s forces can strike again.

Key Dialogue

"DOCTOR: Oh yes, yes. My word, this is a splendid piece of work, Anne. ... Very wise. Let's have a look at this. ... Yes, this should control the sphere all right, but would it override the commands issued by the Intelligence, I wonder?"
"ANNE: No. No, I'm afraid it won't. I just didn't have the time. Do you think we can do it?"
"DOCTOR: We can do it if you've got the right bits and pieces."
"EVANS: Hope I'm not disturbing, Doctor, but Staff asked me to give you this. ... Here, you don't think I had anything to do with these Yeti, do you?"
"ANNE: Doctor. The other models. They've gone!"
"DOCTOR: It's the fungus from the tunnel. I thought if we examined it, it might give us a clue. I must get this dismantled. It's like holding a time bomb."
