You had until the seventh announcement. That much was clear. Everything else had to be earned.
Zhou Qin offered the log, but not her trust. Chen Mo offered his knowledge of the exit, while withholding whatever made that knowledge possible. Lin Lan offered to compare tickets, provided she was allowed to keep hers in sight.
You could inspect the physical evidence: the yellow tickets, the stopped watch, the paper log, the mirror. You could separate the three strangers and see whether their accounts survived without one another. Or you could test the announcement yourself, accepting whatever it chose to record about you.
None of those choices was safe. They were merely different ways of becoming responsible for what happened next.

The speaker clicked again.
This time, you were ready to act.
