Toward the very beginning of this episode, the sliders jump into a wormhole that is just above the ground and off-screen to the viewer's right. When Quinn jumps, his feet can clearly be seen landing on solid ground.

During the teaser, Maggie is seen in the background struggling with the monster on her face, before it flies there.
The Sliders exit the vortex into a park. They land on what seems to be a mattress that's hidden by leaves and grass. There's an noticeable slope on the ground and their feet move and stretch the ground unnaturally.
Wade announces there's five seconds left on the timer countdown near the end of the episode. Nearly ten seconds pass before she opens the vortex.
The timer beeps and Rembrandt says there's one minute remaining. However, a minute and a half pass before the timer's activated.
There's no sound effect when Maggie breaks a man's arm.
