So : Terry's being fitted up to waste time. Jo must've known he would have to be released due to lack of evidence so going through the motions.
Buckells seems to want a result. Jo's not getting it. I think Jo's in on most of it, including the botched paperwork enabling the gap in surveillance.
Still finding Farida's behaviour odd. I wasn't convinced by the tears to Steve on the phone when she told him that "he doesn't know what she (Jo) is capable of". I thought she was putting on an act.
And she's always around but sidelined and not really taking an active part (although it's her picking up the phone to whoever makes the initial call to MIT). She's looking on worriedly when the gunman goes down in the ambush and she's there at the scene of death of the CHIS.
Kate seems to be more involved (perhaps as a DI whereas Farida is PS). Is she jealous of Kate? Does she have something on Jo?
