Just for shits and giggles, I'll go down that guy's post. I do not think he's a bookreader at all
He got this right, but not entirely. "By mouth" reads as a very specific sort of symbolism, which is the sort of reads he seems to make, and it didn't happen
1. Everyone seen eating fruit last episode is killed by mouth: Renly (Smokebaby), whore (scepter), blond torturer (rat).
2. Brienne fights the Smokebaby but can't stop it.
3. Smokebaby kills Renly covertly (e.g. suffocation while sleeping) so Stannis can step in with apparently clean hands.
Anybody who's into figuring out symbolism and how stories work would have guessed that A Man Has A Thirst guy was going to become a bigger character. Relation to The Brotherhood and helping Arya is a pretty logical place to go. Personally, I knew he was a legit character because I looked at the cast on HBO. FYI, last year, TWoP thought the "hooded dude in the cage" (whom this guy turned out to be) was Ser Barristan or a couple others I don't remember
4. A Man Has A Thirst returns to help Arya. He's a member of The Brotherhood.
Didn't happen, not gonna happen. Pycelle wouldn't have poisoned Tyrion because his role as ear was more important, so the vial isn't secretly not laxative. And Tyrion wouldn't dare give Joffrey the shits; waaaaaaay too much risk there in getting it done, hoping Teh Joff doesn't get super mad, etc
5. Tyrion finds a good use for the laxative Pycelle gave him episode before last and Joffrey gets unclogged.
Could happen, but I doubt it. The magic doesn't work that way. Also, it's the poster's standard line of looking to a few pieces of potential foreshadowing. Personally, I have Davos betraying Stannis due to his son dying by fire like Melisandre alluded to. But overall, it looks even more likely that Davos WILL NOT betray Stannis. That's one of GRRM's things i.e. his honorable men are really fucking honorable. Ned would not break, Jorah is loyal to the core, and Davos will be loyal to the core IMO
6. Stannis becomes evil and Davos must turn on him.
It's almost too obvious to happen, and I suspect it won't. Who's richer than Tyrion? Who treats Bronn better than Tyrion? I think the superficial look at Bronn is that he could betray Tyrion, but the deeper look is that it would be next to impossible for him to do so
7. Bronn betrays Tyrion for money.
I think this line looks really easy to figure out from the standard perspective, but that they might not be playing Sam like that. This is the sort of character development that happens in Hollywood comedies, but GRRM doesn't play that way, it seems. Something like this could happen though, but I'm not sure it involves "saving Jon" GRRM has yet to play a line that simplistic and standard
8. Sam's courage is tested and he sacrifices himself to save Jon.
Not this season he ain't. Or maybe he will at the very end. He does have to die because he gave the special sword to Jon and eventually Jorah is gonna have to see the hilt, and realize that his late father trusted Jon (which will forge an eventual Dany/Snow alliance/marriage IMO). Maybe Mormont does die this season, but my guess for why the poster thinks so is because of the foreshadowing of Mormont giving Jon lessons on how to lead. He likes that sort of foreshadowing speculation
9. Lord Commander Mormont is killed by a White Walker.
Naw he's sticking around. Who's gonna kill him? Teh Joff is probably the only one, but I bet he wouldn't dare. LF is gonna be brokering an alliance between the Tyrells and Lannisters while secretly looking to broker a marriage with Margaery for himself. LF is in this for the long haul. For a while I thought he was a goner cuz some of his arcs completed, but he's picking up so many more important roles. Also, he's got his own house sigil; that means he's super important. Just think on that, why would GRRM even mention he's got his own sigil (more than once) if he wasn't keeping him around for big things?
10. Littlefinger loses his head.
