Dalek Incubation Chamber Viewing Portal Activation Button

The viewing portal button is pressed by Sarah under the Doctor’s instruction, activating the mechanism that allows the portal to be uncovered. This small but deliberate action symbolizes the companions’ reluctant participation in the Doctor’s plan, as they are drawn deeper into the moral quagmire of his genocide. The button’s activation is a turning point, marking the moment when the companions can no longer ignore the reality of the Daleks’ origins and the Doctor’s intentions. Its simplicity contrasts with the gravity of what it reveals, underscoring the irreversible nature of the Doctor’s decision.

The viewing portal button is a mechanical control that activates the portal, allowing Sarah to see into the incubation chamber. The Doctor instructs Sarah to press the button, which she does, revealing the green-lit interior and the grotesque, embryonic Daleks. This object plays a crucial role in the narrative by providing visual confirmation of the Daleks’ vulnerable state, thereby intensifying the moral dilemma the Doctor faces.
