Ok time to get my season 8 predictions and speculations on the record, mostly for what I think the first half of S8 will look like. As far as I'm aware, nothing from S8 has leaked yet so these are 100% my own personal musings submitted for anyone who cares to read them.
-Dany is gonna end up being preggers. Not a surprise to anyone, this is being telegraphed pretty hard.
-Bronn catches up with Jaime on the Kingsroad in ep 1. No reason for him to stay in KL, he was already basically looking for an excuse to bail on Cersei's cause anyway. Maybe he managed to take a few loyal men or some wildfire jars with him. Wildfire is definitely a piece that is still on the board that will be played again before the end.
-Jaime and Bronn might pick up the Lannister garrison in the Riverlands (maybe Ed Sheeran too?), Jaime might get a reunion with Edmure if they stop by Riverrun. No reason for the Riverlands to stay out of the war in the north (though we still haven't heard from Dorne's completely intact army, so who knows?)
-By the end of ep 1, the following characters will have reached Winterfell (cue mass complaints about travel time): Jon, Dany, Davos, Gendry, Jorah, Tyrion, Brienne, Pod, Missandei, Grey Worm, Varys, The Hound, The Unsullied, The Dothraki, Drogon and Rhaegal. Plenty of reunion scene potential here, Arya x Gendry, Arya x Hound, Sansa x Hound, Sansa x Tyrion, Jon x Arya, Bran, Sam, and Ghost (lol).
-Lots of characters are probably going to meet for the first time at Winterfell. Possible meetings of note: Jorah x Lyanna, Dany x The Starks, Dany x Sam (she killed his Pa and Bro), Sansa x Varys (they both lived in KL but I'm not sure they've ever spoken, he might inquire about LF) Also, seeing Dragons at Winterfell is gonna be surreal.
-Sam and/or Bran will tell Jon about his true parentage in the final scene of ep 1, bank on it. What happens to this information after that and how others respond to it will be the primary (only?) source of political-ish intrigue for the final season. Wonder if Varys will back Jon since Jon will have the better claim and Varys is known for doing shit like that.
-Euron is gonna arrive back in KL w/ The Golden Company in ep 1 (travel time rabble rabble!), folks have speculated whether or not Daario or Jaqen could be among them but I kinda doubt that. Euron's probs gonna be like "ok so we can fuck/get married now right?" and Cersei gonna be like "ugh, I'm just so tired right now, good job tho keep it up"
-Yara is probably prisoner aboard The Silence rather than at Pyke because that's just more convenient for Theon. Guessing her rescue, however it happens, will be wrapped up by ep 2, and she may not make it out alive. Euron may not last that long next season either.
-Jaime-Bronn arrive in Winterfell by ep 2 and hoo boy that's gonna be awkward. Brienne and Tyrion have to vouch for Jaime to keep everyone else from murdering him. He and Dany will probably have a tense af discussion about The Mad King. He's probably going to try and apologize to Bran who will be indifferent, might even tell Jaime that he's glad he pushed him. Bran will probably also talk about seeing him kill The Mad King.
-Bran saw the WWs breach the wall so everyone at Winterfell should know how close the army of the dead is by now and will probably be in panic mode.
-Tormund and Beric are pretty much stuck on the top of The Wall unless they hoof it over to Castle Black to use their elevator, so that's what they'll do unless D&D say "fuck it, they climbed down.". We'll see Ed again, yay. Not sure what they're play is from here. Will The Night's Watch abandon their posts since the Wall has been breached? They gonna try and make it to Winterfell before the dead get there? I have a bad feeling about Ed and Beric dying early on. I do wonder if the Night King could resurrect Beric given how many times The Lord of Light has brought him back. It would be pretty cool if NK tried to rez him but the body just bursts into flame, LoL basically saying "nope".
-With Gendry's return I'm wondering if he'll be sent to rally the Stormland to help fight the WWs since he's the only Baratheon left, but where the hell are they gonna find time to do that (I guess Gendry could run all the way there)? The only way I see this happening is if Davos doesn't go to back to Winterfell, but instead right from ep 1 goes with Gendry to Storm's End with a letter from Dany/Jon legitimizing Gendry and Davos does his usual hype-man shit to win them over.
-I can't see any scenario where our heroes aren't forced to abandon Winterfell at the end of episode 3 or so. It's gonna happen and it's gonna suck to let them take it, but there's zero chance the WWs are stopped before even leaving The North which means Winterfell is dunzo....again. We just remodeled not that long ago, dammit!
-WWs in Winterfell...you already know what the final scene of that ep will be. NK casually strolling through our fav hangout spot: The Winterfell Crypts. The skeletal remains of generations of Starks clawing their way out of their tombs. Even if this happens I'm not sure they would show undead Ned (holding his head!), that might be too manipulative.
