Lucas a good addition?

When I first started watching Spooks, I was a huge fan of Tom Quinn/Matthew Macfadyen and Adam Carter/Rupert Penry-Jones, so when I say Lucas North is my favorite of the bunch, it's really saying something. I find his character to be the most interesting of the alpha-male roles they've written in the show. While the human aspect of being a spy, with its trauma and breakdowns, has been explored in almost every other episode of the show, the circumstances surrounding Lucas' imprisonment in Russia takes a whole different look at it. It's a fascinating story line to follow, that of the relationship between Lucas and Harry and also, Lucas' backstory.
