Series 9 Rumours & Speculation

[AnnMarie]

As I think this is my first official post I trust that someone will gently correct me if I haven't done this appropriately.

Here is my question and it is bothering me more and more since Mr. A started saying "Lucas isn't who we think he is..." while promoting Strike Back. At the end of series 7, after Connie is blown to smithereens just after telling Lucas that she was the one who betrayed him, Lucas becomes almost frantic that he MUST speak to Harry right away which is when they realize that Harry's been taken. What was so important to Lucas that needed to be said to Harry right then...was that EVER revisited? Could Lucas been about to tell Harry that he has betrayed the service because he thought himself betrayed by Harry and others. Did that ever have an explanation? I bring my humble question to those who would know...
