We've seen the inside of arks before, but Nolan and Tommy's exploration of this most recent ark fragment revealed something new and intriguing - a human body in what looked like stasis. And, hey, it's Brian J. Smith from Stargate Universe! A nice reveal, handled well.
The entire scene of Nolan, Rafe, Amanda and McClintock had a warm, funny, friendly vibe to it...but also filled us in on a lot of Earth's history between here and the arrival of the aliens. The Bravery Nine, the references to Twilight...it all made for an oddly comforting mix.
Stahma Tells It Like It Is
The affair between Stahma and Kenya is surely sexy, but it stands to cause shockwaves on other levels, too, as Stahma lays out in telling Kenya why Datak must never know about it. The lady Casti certainly has some political savvy about her.
Rafe By the Lake
If there's any human in Defiance who's connected to the old world, it's Rafe McCawley. So, it stands to reason that he was the perfect person to talk Gordon down from his lake ledge, with a gruff, fatherly demeanor that spoke to what was left of the American astronaut.
Its arrival might seem like an afterthought given how it appeared in what amounted to the episode's denoument, but the hemorrhagic fever that shocked Doc Yewll is sure to have big repercussions for Defiance (and is also a big tie-in with the video game).
