Doctor tests alien communication device

The observation room in the underground laboratory serves as a critical monitoring hub during this event. Masters, under the Doctor’s direction, watches the room’s equipment for any reactions—human or alien—to the Morse code signal. The room’s sterile, confined space amplifies the tension, as the Doctor and Liz await any sign that their covert communication attempt has been successful. The observation room’s role as a surveillance point highlights the power dynamics at play, with Carrington’s forces unknowingly aiding the Doctor’s efforts to expose the truth.
