[spoilers] Lucas as Section Chief

[HellsBells]

I really feel we needed a whole series with Lucas as Section Chief, so that the team could build up trust and understanding. They didn't have time to behave as a strong team who trusted each other.
It was interesting that Lucas had to think about accepting the position of Section Chief, rather than taking to job straight away. And even then only apparently took it so that he could access Vaughn's file.
