Fetch- Andrew Possessed Fetch

  “Fuzzy. Yeah. So are mine,” Andrew said. “But I do remembering wanting to get back at someone who hurt me. I think I attached myself to him. I got into his soul, made sure he couldn’t move on when he shoulda died. I remember I wanted him to suffer, the way he made me suffer. But I don’t remember what he did. I just know I hung on, no matter what they did to him to try and save him. I wanted him to hurt!”

  Jake was quiet. Then he said, “So where is the person now, the one you’re angry with?”

  “I’m not sure. I know I was in him when we got to this big place with lots of cool stuff. All I can remember after that is wanting to be everywhere. I can remember being all over the place in all kinds of things. And I remember this animatronic dog, Fetch. He broke down in a thunderstorm. Sucky toy. Not made well.” Andrew made a raspberry sound. Then he sighed. “So I think I was in Fetch, sort of. I think that’s how I got here. I don’t know why I think that. I just do.”
