Do we all agree that Tyrion will survive?

I must disagree. Of all the characters, I think he is one of the most likely to make it out alive.

Fan favorite who they ruined to help push other characters.

From the beginning, they make Tyrion a Stark named Lannister. Rather than a Lannister with a few Stark traits like in the books.

Then they have made him seem foolish and make one bad decision after another to push other characters. Grey Woman and Missandei in Meereen telling him over and over again not to trust the slavers. Them somehow they show up with no warning. Pfft. They couldn't have Dany making mistakes, so the whole battle strategy in Westeros was his responsible. Now he's responsible for Dany trusting Cersei, when she had no choice anyway.

A couple maudlin scenes fits with making Tyrion an idiot that everyone likes.

Pretty much everyone was doing that "we're all doomed" riff last episode. If this is a sign of impending death it's going to be an awfully empty final three episodes with nobody around. What about Arya, let's sleep together because I don't want to die a virgin? That doesn't mean she's toast either - but it's a much bigger foreshadow than a little gallows humor.

Thinking we can read the tea leaves and predict who they'll kill off is silly. If the writers have done their jobs at least some of those deaths will come as total shocks. Both who dies, and how.
