Thal Guards' Infiltration Suits

Bulky armored suits stripped from a pair of Thal guards after Doctor and Harry knock them unconscious. The suits are heavy with reinforced plating that clatters when the Doctor drags one into hiding, their dark-gray surfaces dulled by dust and movement. Harry struggles with the unfamiliar weight, fumbling with the seals and hoses as they flee, the suits’ opaque helmets obscuring their faces while granting a narrow field of vision through scratched visors.

Before: Proposed conceptually as a solution to the lack of scientific credentials

After: Its practical implementation becomes a conditional agreement contingent on further planning and authority
