Doctor and Tremas uncover Melkur's energy source

The Doctor and Adric face immediate execution when Kassia collapses under Melkur's influence, fracturing her veneer of authority. As Seron presses for clarity on the Keeper's attack, the Doctor seizes the moment to pivot the narrative from accusation to investigation. Spotting Tremas's tricorder, he recognizes a kindred mind and pivots to scientific analysis, proposing to examine the high-energy force fields tied to Melkur's corruption. This marks the first tangible collaboration between the Doctor's theoretical expertise and Tremas's diagnostic tools, crystallizing their joint effort to pierce the veil of the Traken Union's unraveling defenses and pinpoint the specific fractures in its shielding against Melkur's malignancy. key_dialogue: [ DOCTOR: Yes. Someone here, or someone very near here. SERON: One of us? DOCTOR: The least you can do is hear what we have to say. DOCTOR: No, not at all. A high energy beam.
