My DH was shocked, too. I've read the books so I knew what happened and I was dying to tell him. It was so hard during that scene to stay quiet and not give anything away. When it was over he said he wasn't expecting that. So now he wants to know what happens to the Mountain, if he lives or dies, but I won't tell him that either.
At first I didn't like all the unexpected deaths of central characters, but now that's one of the things I like the most. NO ONE is safe and even though I know that, I still get invested in the characters.
There's 1 death in particular that I really hope happens this season. I don't want to have to wait for next year for it.
This has been a good season. It's moved at a pretty fast pace and has had very few dull moments. Best season so far, I think. I wish we didn't have to wait so long between seasons.
