In the beginning of the episode you can see the corpse breathing in the casket.
When agent Mulder, agent Scully, and agent Bocks are examining the murdered prostitute at the crime scene, you can see her chest breathing under the blankets.
When Scully and Pfaster are rolling down the stairs, as they reach the bottom step a crew hand is visible on the left hand side rising up to stop them falling into the camera.
(12:41) As Pfaster drives down a street in a scene set in Minneapolis, a bus with a "UBC" (University of British Columbia) display can clearly be seen. Additionally, a Save-On Foods store can be seen. Save-On is a grocery chain based in British Columbia and only has locations in western Canada.
