At the end of episode 3, Nick was going to tell Maya the truth. However Maya thinking that Nick was having an affair collapsed with a fit.
In this episode even though Nick has cleared the matter up regarding he and Abigail, his handler for some unfathomable reason wants to contain things by getting Nick to confess to Maya to an affair with Abigail. It makes no sense. Worse still the handler has forgotten to tell Nick that the story of Abigail's death is in the newspapers as it seems to be clear that writer Nick does not read the papers.
With Maya being diagnosed as epileptic and with her new job as the head of the DPP, I guess Nick telling her of his affair is going to cause more pressure, especially as he talks about Abigail in the present tense.
Maya now has doubts about Nick and starts to investigate his background. The authorities have put pressure on the editor of the newspaper to promote Julia to Royal Correspondent and get away from her current story. However a veteran journalist at the paper takes an interest in one of her investigations regarding the discovery of Abigail's body and who she really was.
This was an uneven episode. Again something tells me that this was a 4 part series that is being stretched out. The US set scenes of Rudy Jones in hospital just seemed superfluous to me.
It looked like Nick was going to tell all to Maya, now it looks like Maya is going to find out about him.
