I like how MGM and the Sci-Fi Channel were always looking to cast actors from fantasy and SF TV shows, mainly the Treks and Farscape, to wring a little publicity from them and try to get a few thousand more viewers to stay home on Friday evenings and give Stargate a try. And so one day in August 2005, a few thousand people who enjoyed watching Firefly on DVD, probably more than the ones who watched it when it was first broadcast, tuned in to see actress Jewel Staite looking not a darn thing like Kaylee.
I kid, I kid, and for all I know, the Sci-Fi Channel didn’t say a word about Staite being in this episode, but it amuses me to imagine somebody in their promotion team seeing shots of Staite in her Wraith makeup and realizing that everybody who fell in love with Kaylee in her pink frilly “Shindig” dress would be getting something very different here.
Anyway, this is not as much a two-parter as it is a case of everything that happens in “Instinct” fueling the events of the next episode. Part one is a splendid horror movie where a monster in the woods attacks the people of a small village three or four times a year, and it turns out a young female Wraith who was adopted as an infant refugee is living in an old mine shaft by a fledgling scientists who says that it cannot be the girl; he has developed a chemical that stops her from needing to feed on humans. But it turns out he’s wrong, everything gets worse, and she infects Sheppard, who, in part two, starts mutating himself, so everybody needs to find a cure. This half is mainly studio-bound and doesn’t do anything we haven’t seen before, although there is an interesting callback to the previous season’s “Thirty-Eight Minutes” as well as the two most obvious Redshirts who ever Redshirted. They might as well have named the two characters “Expendable” and “Lucky.”
