I’m curious as to how the Hepworth/Faisal subplot is going to resolve itself.
My guess is somehow Hepworth is going to find out that Faisal supplied the diazepam to Joanna leading to a confrontation between the two of them that ends up in either them both dying or Hepworth killing Faisal and then Hepworth being charged with his murder (so he still gets his comeuppance despite not being guilty of Joanna’s death).
I feel sure there will be some other confrontation between the pair of them, to make the encounter when Hepworth rear ended Faisal a meaningful prelude (otherwise what was the point of it).
Faisal has to get found out, but given how much Hepworth has been set up as the bad guy I can’t see the end for him being just him being in the clear, something has to happen to bring his storyline to a dramatic close.
