The Sliders stroll by the women hanging up their laundry twice.
The distance between the truck and the vortex suddenly grows when Quinn and Colin exit the vortex.
When Colin meets Susannah with the barrel of apples, someone nearby is meant to be sweeping the boards, but his broom is not touching the ground.
In Colin's workshop, the timer reads 1:57. Approximately thirty seconds later, Rembrandt tells Quinn that they have less than ten minutes until their next slide.
When the Sliders walk with Colin to his town and talk about the Amish, a separate shadow appears on the ground next to Maggie that keeps up with the group. It's possible that the shadow is the camera on a track.
The Sliders are going directly to the world of Quinn's brother when they enter the vortex at the end of World Killer (1998). Nonetheless, they're wearing completely different clothes when they exit the vortex at the beginning of this episode.
