Plot-holes

[Byatil]

Yes, sorry, I suppose Ruth and Harry had some decent development. It was just Lucas, Dmitri, Beth and Tariq who were never explained very well.

I don't ask for "realism" in the living day to day existence of what we know as humans sense- I am intelligent enough to know that my drama is fiction, but the story has to work in the fictional world created. In the Spooksiverse, Jucas cannot work (show me a man or woman who can reconcile coherently Lucas series seven and eight with nine and I'll eat my words gladly) and in fact undermines believability already for series ten. If Jucas can happen with no rhyme or reason why can't Harry the cross dresser? Why can't Ruth the Chinese spy who has been using Harry secretly since series two unbeknowkst to the viewer? The answer is there is no reason it can't and that IS worrying.
^I completely agree with this; it is worrying. How far will our believability be stretched in the name of "good drama"? Hopefully S10 will be a much stronger series.
