Building inspector Robert Cox arrives at Cora's house to investigate the curious oils. "The way it's running down the wall makes me believe that it's something in the room," he says. "I've got a portable microscope. We're going to look at the materials itself."

Cox examines the walls through a microscope, revealing a startling finding. "Well, it's not even on the surface," he says. "It goes back to my thoughts that it's splattered onto it."

"Wherever it???s coming from is from inside the room," says Indre. And I think that's an important bit of information that we're now gonna be able to focus on as we continue our investigation."
