Grover traps Sarah in the secret bunker

Grover guides Sarah into a hidden filing room beneath his office, feigning helpfulness while secretly leading her to a concealed bunker entrance. He exploits her trust to expose a classified map revealing a subterranean facility right below them. Once she deduces its location, he spins the door shut behind her, sealing her inside the very structure she sought to uncover. Red-painted brick walls and harsh lighting greet her as the mechanism locks into place, signaling her transformation from investigator to captive and Grover’s turn from seeming ally to active adversary. key_dialogue: [ GROVER: After you, Miss Smith. ]
