^^FWIW I think the story would benefit from killing Tyrion. It would provoke Jaime to become the counter to Tywin and Cersei, which is a bigger deal than Tyrion doing it. Furthermore, it would make Tywin the ultimate bad guy, which would make Stannis and Littlefinger the good guys

Part of me wants Tyrion to die a horrible death and Tywin to love every minute of it. I don't think that will happen though. I'm sticking with him living because I think the show is operating on level 2 thinking and not going beyond it i.e. its deaths are the opposite of what they look like they will be. I don't think the show will ever do level 3 thinking, where they know that the audience is expecting a surprise, so the surprise is not giving the surprise.

Anyways, yeah, if they were going to kill Tyrion, the cliffhanger would be about how Tyrion was gonna get out of it, and the death would come suddenly and surprisingly
