(i'll post again so Erin will see Darren)
Erin's eyes adjusted to the night's darkness, the stars overhead yielding a little bit of help, but not much. She slowed her gate, studying the street and buildings around her; not just looking for Fiona, but also scanning the shadows to make sure nothing was going to jump out at her.
A couple blocks down, while scanning the rooftops, she spotted a figure on the top of an old apartment building, barely silhouetted against the sky. Erin dug her binoculars out of her backpack and peered through them at the figure. She recognized him as the guy she first met in the hospital, who had left as soon as she came downstairs.
