VERY good guesses. I sure hope LF gets it soon. Fucker is pissing me off.
There's a really original thread at the 'W' comparing LF to rabbits/hares (like 'Peter Rabbit' the famous meddlesome rabbit). I wish I could remember the author. Linking that to Arya being dubbed 'Lumpyhead Rabbitkiller', together with her observation that rabbits are faster than cats, but are at a disadvantage in the trees, I expect Littlefinger to be taken out at Winterfell -- after all, Winterfell is a giant stone tree. That said, I doubt that it's going to be Littlefinger next episode, since most would be pleased to see him go, and the idea for maximal shock effect is to take a character in whom we're invested emotionally. That's why I think it's going to be Drogon. It would be typical D&D -- get us all complacent after Drogon narrowly escaped harm in the 'field of fire' episode, then Dany loses him to the ice, which gets our neatly built-up Manichaean world view of ice vs. fire all scrambled up and out of joint. Quite poetic, really -- even for them. But, that's because it isn't their idea -- it's GRRM's and it's possible to trace from the text alone. It's a bit silly speculating over here on my own, given that you all know the plot ahead of time from the leaked episode. I hope if I'm right you're all suitably impressed...
Who do you guys think are most/least likely to meet the Stranger in Ep 6?
Drogon or Littlefinger.
From the shot of the foolhardy bunch of seven fleeing the army of the dead, there's only one way they're getting out of that pickle, and that's Dany having a change of heart after nostalgically perusing the cave paintings in the Dragonstone cave of swimmers in Jon's absence, leading her to take off with her dragon(s) to the far north to swoop in at the last moment (in the episode's climax) to set the army of the dead on fire. The price for saving her human friends will be the loss of Drogon to the Night's King, after which Drogon -- all hail the Ice Dragon -- will be raised from the dead. Won't that be a sight to behold?! What a delectable irony -- the dragons that were supposed to combat the Long Night will now be potentially instrumental in freezing Westeros with their icy exhalations into a rock-hard popsicle faster than we'd ever imagined! At that point, only one hero will do to fight the battle for Drogon's mind -- enter Bran. Let's hope he's sorted out the mental fragmentation by then. His skinchanging of the raven flock was none too convincing against the Night's King's severing powers, and skinchanging a dragon will take the full concentration of his greenseeing powers. In fact, it's going to take his life. It's a flight of no return. (D&D should let me write this stuff! )
I will say it actually hit me--I felt bad for the remaining two.
