There had been a nightmare. People vanishing. Dinah walking on a road that lead off a cliff. Falling... She'd woken up as dawn was on the horizon, and left the Clocktower to get coffee, unable to get back to sleep.
Recent phone calls hadn't helped. The streets already had early morning commuters on them, the sounds of the city waking up. Espresso from her favorite coffee cart; and a walk to see the sunrise from her favorite Metro stop.
It was the silence that tipped her off. Between sips of espresso, the noise level... dropped. Dinah turned around to see the streets were empty of cars. Empty of people.
She dropped her coffee, and ran for the Clocktower,
phone in hand. [for one]
