Jang handcuffed Song Yin-gyung to the train to ensure she would stay at her post and pull the lever that disconnected the cars. He needed someone he could trust to execute the plan while he remained at the controls, and the handcuffs ensured she could not interfere or flee during the critical moment.

Foreshadowing: Earlier tension between Jang and Yin-gyung shows their uneasy alliance forming under life-or-death circumstances.

The lever was the emergency coupling release mechanism that disconnected the first car from the rest of the train. Jang instructed Song to pull it at the critical moment to separate the hijacked car containing the threat from the other passengers, effectively sacrificing those in the first car to save everyone else.

Foreshadowing: Jang's drastic plan centers on separating the train at the precise moment to contain the threat.

The subway system served millions of daily commuters in Seoul, making any disruption potentially catastrophic. Kang Gi-taek's threat involved not just the passengers aboard the train but the entire city's population, as the hijacked train could cause massive casualties if his demands were not met.
