Zygon assumes the Scotsman's form

Caber's Disguise Kilt and accompanying waistcoat and jacket undergo violent reshaping under gravitational and molecular reconfiguration. The tartan fabric twists and reknits, tautening around the shifting alien form while preserving the outline expected by Harry, until the ensemble settles into a precise replica of Harry’s ally’s attire.

The glass tubes of the Body Print Device actively vent biological effluvia and airflow during the forced replication, their transparent cylinders capturing Caber’s expelled residue as the Zygon absorbs his form. The tubes glow faintly with interfacial energy, serving as both conduit and cage for the grotesque informational exchange defining this horror.

The recessed Transformative Control Button is identified by Zygon and later pressed, triggering the mechanical phase of the replication cycle. Harry sees it as a mundane intrusion into the unfolding nightmare, its metallic surface gleaming under harsh chamber lights seconds before reality warps and Caber’s face unravels into human semblance.

The Staff Nurse uniform hangs unused above the dais in a secondary alcove, its slightly ill-fitting folds betraying artificial replication. It serves as a silent witness to the horror unfolding, its presence underscoring the breadth of Zygon mimicry across human social roles.

The Body Print Chamber acts as the surgical theatre of infiltration, its cold clinical dais bathed in sterile green light while machinery whirrs with biological appropriation. Smoke curls from dais edges as Caber’s form destabilises, and the air grows thick with metabolic byproducts and metallic ozone, intensifying the sickening authenticity of the transformation.
