[spoilers] Lucas Discussion 2

[Belle]

I will always have a double feeling with that quote; I totaly agree with what DogSoSmall and Byatil wrote about the fact that Harry, no matter what, must keep his trust in his agents or that it would be impossible to work as a well-oiled machine and that Harry's decision to let Lucas find his 'redemption' is admirable; but there's always that little voice in the back of my head that points out that it was Lucas who felt/was betrayed by Harry first, by leaving him to rot in Russia, and that Harry really isn't entitled to make that comment (in Lucas' mind, anyway).
I don't understand: in previous episodes we saw Lucas craving for Harry's trust and the moment he somewhat gets it, he throws it away. What does this mean: that Harry waited too long to show his 'trust' to Lucas and that Lucas was not needing it anymore (which I personally find very hard to believe)?
Does this quote means that Harry doesn't think he has let Lucas down, that he doesn't see the damage those eight years have done to his agent? Or that he conveniently 'forgot' the guilt he obviously felt in S7, ep1? I agree that he must move on, that he can't dwell too long over that feeling of guilt, but it seems that when he says: '... let it eat your soul, not mine' that he lets Lucas down, once again, by minimalizing the blame Lucas has put on him.

I'm sorry if this, again, doesn't make any sense, but I can't seem to get my head arround the evolutions in S9, I don't understand how the characters react towards each other (but, then again, I don't understand the way some people react in real life, too, so it probably has to do with me )
