There’s no major plot advancement this time out, but we get a few good character development scenes. Some are clunky (like the Chloe/Jack one, which feels forced and expositional), and some are merely repeating what we already know at this stage (all the Heller/Mark/Audrey scenes) but the others are devoted to interesting new characters (Margot/Simone/Ian).
As well as that we have Jack doing what Jack does best: proving action and tension in sequences that book-end the episode.
A strong episode, without doubt, but the first one this season to show some strain with regard to moving the story forward. 9/10
