Episode Overview
Cole recognizes a missing boy's face on a milk carton, recalling him from a video he recorded at the train station. He and Mel dive into the investigation and discover that an alien Odulian has taken over the boy's body, using him to lure vulnerable street kids for experimentation. The Odulian, along with another alien disguised as a doctor, is attempting to gather chemicals for Zin. The aquatic Odulian narrowly escapes their first capture by hiding in Lake Michigan. Realizing the alien requires specific elements to survive, Cole figures out that the lake's high zinc content won't work. He tracks down the necessary chemicals and locates the alien's lab. Although the alien doctor manages to flee, Cole ensnares the Odulian in a net to prevent its escape and successfully extracts the alien's life essence.
