Could see the way the wind was blowing, but with Mercurio you can never be sure of the details. All I will say is that everyone seems to continually underestimate Lisa...
As a bit of a heads-up, it's apparently been confirmed that the series finale in two week's time will be 90 minutes long (you may remember that the finale of "Bodyguard" was extended too). Will probably discuss this more closer to the date...
I just knew Lisa was going to turn on him ,(first thing I have sussed out!). Is the wpc with AC12 a bent cop? I have my suspicions and I am not too sure about Hastings new love interest, especially since he has now rejected her.
Has she though? Why was she sobbing after she was alone in the corridor, after the guys had dragged John's body into the room where they'd been playing cards?
The two big teases that Mercurio has been playing out on us this series are:
1) Is Hastings "H"? and
2) Is Lisa undercover?
I'm going to stick my neck out and say "no" to both, but either way I think the key in both cases will come down to their backstories.
For Hastings, there has been a lot of speculation dating back to the very first series about how a Catholic policeman rose up the ranks in the RUC. At the end of Series 4, Mercurio pretty-much stated flat out that the next series (i.e. this one) would address that (or at least start to, seeing as a 6th series is confirmed too...).
I'm expecting a lot of revelations about Hastings background in tonight's episode, and I'm relatively confident they'll be mostly good ones... 
As for Lisa: I'm still uncertain, but I think what we're seeing is really down to good writing and acting combining to show the emotional struggle Lisa's constantly under from being a woman with some remaining morals in a very macho, amoral world.
The reason (IMO) why we the audience remain somewhat suspicious of this is that we're not used to emotional depth in LoD (think about how little we really know about what makes Steve and Kate tick after all these years...). The thing is that while Mercurio is a master of plotting, he's never been all that brilliant at characterisation, often relying instead on top-class actors to pull it off. I still have occasional nightmares about that dreadful SF series of his "Invasion: Earth", where all the characters were only defined by their job titles...
