Main Characters in this Episode
Sheriff Jack Carter: So first, my PDA has a camera. And now, black holes are everywhere? People need to know these things!
- Goof (continuity error): When Jo and Allison are talking in the ship, the clock behind Jo counts down to 40 minutes, 1 second. The camera cuts away to Allison for several seconds, then back to Jo; the clock still shows 40 minutes.
- Goof (revealing mistake): The number plate on Taggart's truck, before it gets sucked up, is: DSG 384, which is Sheriff Carter's plate number and has been for the majority of the series.
