DH and I are so very sad that we have twice now worked our way through all seven series and then started again - not all at once, you understand; a couple of episodes a week. Still pretty sad, though .
I never knew about the Josh Lyman/Rahm Emanuel link. But I did know that the actor of Josh is married to the actress of Lois from Malcolm in the Middle!
Best character of any drama series ever is Toby Ziegler - dark and complicated.
