Well...

The Mountain and the Hound fought to the death. I thought it was a little unrealistic but it was gory. The Mountain didn't even look human with demon type red eyes and even when his helmet came off he looked like a Balrog. Didn't want Sandor to die but I suppose it was his destiny. Khaleesi did in fact go insane. I thought for sure Arya was going to confront Cerci.
