I think we're getting ten episodes this season. If so I think we're about halfway through. It makes sense that the plot is opening up, as it were.
This episode was more about revelations than anything else, finding out about the monitors was interesting, I'm assuming (probably rightly so) that that french woman is going to be Kasima's monitor. As for Sarah, I'm leaning towards Vic as her monitor. Why else would they bring him back into the story at this point?
