Despite Karly’s warning, I headed straight for the park. It drew me into its darkness. There was no one around, just empty sidewalks and shadows where the glow of the light posts didn’t reach. The night hid me, but it hid him, too. I walked across the wet grass to the dense trees lining the riverbank, where my gaze couldn’t penetrate the wall of tangled brush. The sewery dankness of the water intensified as I got closer, like the blooming of a corpse flower. The wind was dead still, letting the smell hang in the air.

I thought about calling out to him. I was sure he could hear me. Let’s end this now. You and me. But I didn’t think he’d show himself yet. He was like a virus, stalking his victims silently and only coming into the open when he saw that they were vulnerable.

In the quietness, I listened to the chirp of a lone cricket, like a spy issuing a warning. A mosquito whined in my ear, and I batted it away. Keeping my eyes on the riverbank, I returned to the trail and headed north. As I walked, I curled my fingers around the handle of the knife in my pocket. Every few steps, I looked back, trying to pick out a silhouette in the trees.

No one was there.

I kept looking for the Dylan who lived in this world, coming home from work. I wasn’t sure what emotions I would feel when I saw him. We’d have the same face, the same body, the same walk, but he had so many things I didn’t. Karly and Ellie were waiting for him. When he was back in our apartment, he’d kiss his little girl and sleep next to his wife. I had no one waiting for me in my own world. They were all gone.

All I could do was make sure that this Dylan Moran got home safely to his family.

At least, that was what I told myself I was here to do.

Ahead of me, the trail split. One way led up to Foster Avenue. The other way led down into a tunnel beside the water. I took the tunnel, where lights illuminated rust, swirls of graffiti, and a swarm of bugs. The last time I’d done this, I’d found Dylan Moran’s body in the process of being consumed by rats. It made me wonder if I was already too late. Maybe the Dylan of this world was never coming home from his job. Maybe my doppelgänger had left his body beside the river, his decomposing flesh contributing to the rotting smell in my nose. But I couldn’t let myself think that way. I had to keep going.
