There is a three-year-old in the subway holding a stuffed bear and a suitcase.

She is at the end of a long line of similarly provisioned kids.

The line snakes out of sight.

The evacuations have begun.

As you snap the clasps closed on another suitcase you call out, “ok now the four-year-olds.”

You figure the wardens may just get the six-year-olds boarded before the gas takes hold…if you can keep moving.
