Jo proves her competence to the Doctor

Jo Grant enters the UNIT lab while the Doctor dismisses her as an unqualified trainee. When she quickly summarizes incoming reports on the stolen meteorite and confirms the delivery of vital electronic spares, her sharp efficiency exposes the Brigadier’s accurate assessment of her strengths. The Doctor seizes the report about sabotage at a radio telescope and the disappearance of two scientists, recognizing a critical threat. His abrupt shift from rejecting her to acknowledging her value marks the first true moment of trust between them, as Jo’s competence quietly undermines his prejudices. key_dialogue: [ DOCTOR: Well, now, wait a minute. DOCTOR: Miss Grant, I, er, I, er. Well, I don't. This is, er, a bit difficult for me to say but. Er. Thank you, Jo. I can see you're going to be of great help to me. JO: Thank you, Doctor. Report from one our field sections, sir. Captain Yates. Some kind of sabotage at a radio telescope. Two of their scientists have disappeared. ]
