[spoilers] Lucas. Just Lucas.

Ok, another part Lucas theory.

I think the constant references to "Whose life have you ruined today John" and the ease at which Lucas stitched the other officer up, shows that he has done this before. I wonder whether John set up the real Lucas North 15 years ago and took his identity. The real Lucas North was sent to prison by the Chinese or killed, thinking they had John. That may explain John's explantion to Maya that he probably deserved to go to prison (in Russia) because he always felt guilty about that.

Maybe the real Lucas North is still alive and is now after revenge and has hired those 3 Chinese people to kill John. Or perhaps the Chinese have only just realised they had the wrong person once Vaughn handed them the Albany file. This told them everything and the Chinese now know that John is still alive.

Big holes I know....
