My theories of the next 160 minutes of air time:
Jaime: Dead - by the Mountain. It's too predictable he offs Cersi.
Dany: Dead (Jon gains teh loyalty of Drogo, and Dany gets BBQ'd)
Arya: Dead (this one pains me) one of the Stark girls will have to die. It will probably be Arya. I see a scene where her and the Hound fight the Mountain, she gets a good shot on him, ala Night King, except it works out poorly for her. He crushes her head, the Hound kills the Mountain, and the series fades to black with the Hound holding Arya and crying (I hope to FUCK that's not the case...)
The Mountain: Dead, as mentioned above, BUT:
Cersi: Dead. Bran does his Hodor mind control on the Mountain, and he swords her into a cunt corndog, right before the Hound and Arya show up, with Bran getting whacked to lose the mind-control at that very moment.
I can't see Snow dying, but, I imagine it will be he or Gendry on the throne when it's all done.
Or Bran mind-fucks the dragon, kills EVERYBODY, eats Bran, fucks Tyrion, and there's a trailer for Reign of Fire 2, coming soon to HBO.
