Death is often cruel, and in Westeros it is not always permanent or as it seems.

I would list the few that do seem permanent, but I don’t want to spoil.

Yes, spoilers would be a real problem for anyone who hasn't read the books and is only following the HBO series. There is no shortage of unpredictable tricks and traps. I just found myself sometimes consciously thinking about the author being a cruel bas****, chuckling to himself as he typed.

Regarding producers of the series, I think they've done as good a job as possible when going from a written to a visual medium. Never easy and it's rare when it's done well.
