Leo confronted Sam with truth after Amy went to bed, but she'd have no part of it.
"You're imagining this. It's post-traumatic stress from the accident!"
"It's not an illusion, Sam. These things exist in a kind of energy field that shares space with our world. A sort-of parallel dimension."
"C'mon Leo, listen to yourself. You sound like a Star Trek episode!" She tried to lighten up but Leo remained dead serious.
"I've started to recognize specific creatures," he continued. "There's one that hangs around Amy's room. I chase it away all the time. And there's one next door that keeps coming over, like a cat looking for a handout." He pulled out his notebook and opened it for her. "Look, I drew them."
Sam frowned as she flipped through the pages. "You can't really believe that these things are real."
"Yes I do. It's like everyone lives in the dark but I've been given night goggles. I see what others can't, and I then draw what I see. I'm going to discuss these images with some of my biologist pals at the university. Once we know what we're up against, we can devise ways to protect ourselves."
Sam was silent for a moment. Then she handed him the notebook, her eyes wide with concern. "Leo, you've got to go see Dr Simms again."
"Don't worry. I have an appointment scheduled tomorrow. I know what I'm doing, Sam."
All day long he'd been telling himself that Sam would understand -- eventually. But at that moment when he looked into her face, his heart sank.
Sam was afraid of him.
