I know Brianna & Christi already finished the season, but in case anyone is watching along with them I will say that (up until this point at least) the season had 2 overall themes. The first was that regular humans were capable of being just as bad some of the aliens that we’ve seen. And the other is that the enemy isn’t always obvious (see Rosa, Punjab, and this episode). Not exactly a long plot like we’re used to, but an interesting experiment.
