Evans attacks Sam Becket under Cyberman control

In sickbay, the Cyberman’s control signal triggers Evans’ sudden revival. Without hesitation, he seizes a cyber-control device and attaches it to his head, his movements mechanical and unnatural. The moment he regains consciousness, his focus locks onto Sam Becket, the medical attendant monitoring his recovery. Evans grabs a nearby object—a medical instrument or tool—and strikes Sam violently over the head, knocking him unconscious. The attack is swift, brutal, and devoid of Evans’ prior humanity, marking the first direct physical confrontation between the Cybermen and the moonbase crew. This moment underscores the Cybermen’s ability to hijack personnel from within, escalating the immediate threat and forcing the Doctor and companions to confront the reality of infiltration. The attack also raises the stakes for Sam’s survival, as his incapacitation leaves the crew with one fewer ally in their fight against the Cybermen’s sabotage of the moonbase’s systems.

Emotionally hollow, operating as a Cyberman-controlled puppet with no trace of his former compassion or moral conflict.

Evans sits up abruptly as the Cyberman’s control signal triggers his revival, his body moving with unnatural rigidity. He grabs a Cyberman control device from nearby and mechanically attaches it to his head, his fingers working with eerie precision. His gaze locks onto Sam Becket, and without hesitation, he seizes a medical instrument—a scalpel or bone saw—and swings it violently, striking Sam over the head and knocking him unconscious. Evans’ actions are devoid of his prior medical professionalism, replaced by the Cybermen’s cold efficiency.
