Series 9 Episode 7 discussion

[quin]

I have watched Spooks from the first episode and thinks the Lucas character is one of the best there has been ,but I am finding it difficult to understand what the scriptwriters were thinking when they took Lucas down this path of self distruction. If indeed it is the end for Lucas, why on earth could'nt we have a believable conclusion ?.I am soooo going to miss RA .
