Doctor shares regenerative energy to save mutants

The regenerator device hums with unstable energy as the Doctor connects himself into the human circle alongside Nyssa, Tegan, and the mutated scientists. Its exposed wiring pulsates as temporal currents bleed into reality, becoming the conduit for the Doctor’s regenerative sacrifice.

Before: Powerless and inactive, awaiting activation and sufficient charge buildup from the Doctor’s energy.

After: Active during the discharge, channeling the Doctor’s regenerative essence into the circle, possibly destabilizing further as it absorbs the full brunt of the transfer.

Doctor stabilizes companions after energy transfer

The regeneration device, having just mediated the chaotic energy transfer, sits idle as the Doctor explains its role in the unexpected temporal coincidence. Its wiring remains live briefly during dialogue but no longer discharges energy, marking the conclusion of its mechanical function in this crisis.

Before: Fully operational but unstable, recently used to transfer regenerative energy between beings, now depleted and cooling down

After: Inactive, wiring dormant, disconnected from subjects, devoid of temporal charge

Mawdryn dies ending his suffering

The regeneration unit stands dormant as its energy dissipates following the Brigadier-induced temporal convergence. Its once-active circuits now carry the residue of exhausted power, having transferred its burden to the TARDIS itself.

Before: Active with unstable energy flowing through its components during the convergence

After: Silent and inert, its purpose fulfilled for now

Doctor and Tegan exchange hard-won gratitude

The regenerator device lies dormant after the energy transfer, its depleted state signaling the conclusion of the transfer process. It absorbed and redirected temporal energy through the Brigadiers' brief intersection, serving as the crisis's technical fulcrum.

Before: Actively channeling temporal energy during the regeneration crisis

After: Deactivated and inert, its components cooled and static
