One of the stupidest episodes in the history of sci-fi. What a cringe-fest that one was. When they left Earth and started on flying around on the Searcher. A network gets schedules a show, then sees the ratings and notices they aren't as good as the network would like. Time to make changes.
Lets write characters in or out, change situations, re-do the entire premise of the show.
Of course not. But, it was a fun show, at least in the beginning. The shark-jump came when the changes were made. The show was never the same, and, quickly, was gone.
