Samuel was paying close attention to everyone coming and going on that stretch of street. He couldn't miss Rowan even if he wanted to. And he did want to miss her. He really, really did. Because now he missed her in an emotional sense, and that was not the reminder he needed. He needed to stay focused.
Instead he stood on the edge of the roof, trying to lock eyes with her, before turning to the left and walking away along the rooftop. He was abandoning his post, but he needed to know if she would follow him. The night was still young, the witch probably wouldn't be leaving for a while.
