The group thinks Adam is dead
Jan and Mark reveal that a bullying incident has ended with Adam falling through a grille into a deep shaft. John Tate tries to keep control, but panic exposes how fragile his authority is. Phil, who has mostly stayed silent, takes over when he produces a detailed plan to frame a fictional stranger.
Performance turn: the group moves from noisy panic to listening to Phil. That status change should be visible before anyone explains it.
