So, take this with a grain of salt (or not because #science), but below are the characters who are mostly likely to die in Season 8.
Daenerys Targaryen – 83.77 percent chance of death
Jaime Lannister – 72.91 percent chance of death
Tyrion Lannister – 70.76 percent chance of death
Bran Stark – 66.02 percent chance of death
Cersei Lannister – 60.39 percent chance of death
Jon Snow – 58.99 percent chance of death
Euron Greyjoy – 54.95 percent chance of death
Sansa Stark – 50.28 percent chance of death
Arya Stark – 49.04 percent chance of death
Gendry – 39.87 percent chance of death
It's important to keep in mind that someone having a lot of dead relatives was a huge indicating factor in this analysis, which is why those of Valyrian descent (*cough* Daenerys *cough*) are at such a high risk. Similarly, our beloved Lannister siblings are all at a higher risk simply because of their age. Arya may be a killing machine, but she's a child compared to the rest of the characters. It's surprising, then, that Bran Stark has a fairly high probability of death?
"While it’s a fun exercise to use book details to predict future plot points in the show, it’s ultimately going to be the showrunners who decide the fate of Westeros and all those who are involved," Larkin wrote on DataRobot's blog. "After all, I’m not even sure a machine learning algorithm could have predicted the amount of emotional distress this show has caused, and will continue to cause, as we all wait for the Long Night to come to an end."
Amen to that.
