They moved the freezer in season 5, hence why they found leverty and Johns bodies/parts, it's been evident from the start that they purely use Terry and his place because of his down syndrome, like in season 5 when Terry's "best friend" slapped him round the head and sent ugly bald guy to the fridge and they found laverty who they'd forgotten about. Terry is completely a victim, that couldn't be more obvious.
I think Farida is trying to setup Davidson because she's breaking up with her, and that's why she called Steve, Farida is clearly a bit of a nutcase cuz she's ripped up her clothes n shit over the breakup, I think it'll be a similar situation that happened with Gates, Davidson is probably cutting corners/being pressured into doing the wrong things but is ultimately good, she let Terry go on bail because she knew trying to push for a conviction on him because he would be an ideal and easy scapegoat would be wrong I like Perry fitzpatrick as an actor and think he'll end up being an interesting character for this season I think he'll be very similar to Dot. After season 5 I was a bit disappointed about how they set up Hastings and then totally changed the entire plot to there being 4 caddy's, it was immensely obvious to me that Gill was dodgy as fuck so the ending of season 5 wasn't particularly suspenseful but it made sense I guess, again I don't like the whole 4 caddys instead of there being a singular mastermind all of a sudden, when the entire 5 season has been about catching this one guy, all of AC-12's hard work seems irritatingly pointless at this point (despite their arrests etc) so I'm hoping they wrap it up and move onto something bigger for season 6-7.
In all honesty, I have a suspicion that somebody will die this season, I think it will be steve, his back problems are creating a bit of a codeine addiction which was hinted in the pharmacy scenes, and he's thinking of leaving AC-12 as well, this show would be shit without AC-12, it's what it's built on, so either he won't leave, or he dies. Or maybe Hastings, who knows. But this season I think will be a step towards the next main plot (if they have more seasons) and a wrap up of this current one.
