S18E24 · The Keeper of Traken Part 4

Doctor and Adric stabilize the Source

The Doctor and Adric race to counter Melkur’s corruption as the Source’s energy spirals out of control. Adric, despite nearly being blown away by the volatile force, inputs the critical stabilization code under the Doctor’s guidance. Their combined efforts halt the reversal of the Source’s flow, neutralizing Melkur’s access to Traken’s temporal power. The moment underscores the Doctor’s urgency and Adric’s growing competence, while the Doctor seizes the opportunity to install Luvic as the new Keeper, signaling a fragile shift in trauma’s cycle.
