Finished part 2. It was a good series overall. The first episode was much more accurate than the second though.
The relationship with Simon Overland was factually incorrect. None of those interactions happened and apparently they never even met.
Juicy’s storyline is fictional. She never turned on a fiance.
The handlers are still under suppression orders so that was all fictional as well.
Apparently much of the recordings of Mr Dale were incorrect as well.
Otherwise the story was good - just a few factually incorrect things.
