Am watching this on the iplayer. Late starter and am hooked. Don't want to know the ending as I still have three parts to watch. Will keep an eye out for spoilers!
Who thinks that you-know-who was making up his illness Is it even possible to fake it? So many unanswered questions, the writers have apparently said they have too much on to write a third for a couple of years, drop everything and sharpen your pencils pdq!
The finale kept faith with the previous episodes because it always left you with something to wonder about. The actual finish with the countdown with the anesthetic then a black screen was inspired.
