Sometime between when they'd entered Mercy Hospital and the elevator ride to the roof, it had started to rain. Louis kept a firm grip on the nearby column as he looked cautiously over the edge of the roof. To say it was a long way down seemed an understatement: in fact, between the haze of the rain and the sheer height of 28 stories Louis could not see the ground at all.

Out of his peripheral vision he saw Zoey come and stand next to him. She extended a wary hand out into the rain, clinging to his arm with her other hand. They both watched the raindrops sprinkle onto her exposed wrist and fingers and were simultaneously reminded that this situation was really happening.

"Weird to think this is where it all started," Louis said. "It's almost peaceful up here."
