Going right back to the beginning it seemed odd that Hana, a waitress on a night out with friends was so violently struck by a car that just happened to be driven by balaclava man. Then she's chained up in Farmer's house.
The previous victims worked as prostitutes, but Hana just has a cleaning job on the side, except now we know it wasn't cleaning, or not just cleaning and she works as a prostitute too - one who's had Ilfield as a client.
Michael Farmer's also revealed to have approached a lone woman, who's only just come forward and he's confessed to being 'lonely'
There's also the young woman from the previous episode, the rape victim (?) the one with the unseen crying baby or toddler.
Are all these threads going to mesh together?
I think we're going to find out something deeply disturbing about Ilfield, on top of him being electric saw man that is. He was an AC12 informant seemingly trying to clear Farmer, but I think was also trying to frame someone else.
