(Show spoilers) Back on the Shireen and Olenna's fates

You're definitely onto a running theme this season... loss of power and the downward spiral of many main characters to the brink of destruction. It's one of the reasons I loved ADWD so much - the apocalyptic feel was real haha! I just couldn't imagine (and still can't) HOW anyone was going to come out of this and win. Arya was also blinded going through her ordeal so even though the show's not there and may not go there - she's in a weakened state as well. 

Littlefinger is really working himself into a precarious spot on the show more than he was in the book, but I imagine he still holds quite a bit of power in King's Landing. He wasn't famous for his brothel after all. Olenna's threats probably aren't much to him and he could definitely have her killed easily but Margaery knows who killed Joffrey too - maybe she'll spill the beans on him? But regardless, I don't think they'll kill off Olenna anytime soon - she's really the only Tyrell left to carry the story right now.

As for Shireen, I voiced my opinion on this in the other thread, but I really do not get a strong feeling of foreboding for Shireen. I think maybe they're hoping it looks that way - and they intend to make it pretty uncertain for her for awhile, but I think in the end she'll be spared. It's good suspense to try and lead the viewers along a little bit like that but having Melisandre come right out and suggest it boldly to Stannis doesn't mean it's going to happen in fact it probably means it's not going to happen. They gave it away too easily.

The problem is that Shireen was set up on the fourth season... At that time I thought she might become the heir, but now we know Melisandre has plans for burning her for a while already. I am not saying she is dead for sure, but I don't think this is the end of this matter... There is still some shit to hit the fan on this matter.

As for the Tyrells, on the books as desperate as their situation seems, it always seemed to me that Cersei was the most doomed one. Afterall, Mace is still a powerful lord, Tarly's troops are in the city, Willas and Garlan exist and Olenna is far away in Highgarden. But on the show, their heir and queen are imprisoned (and the HS seems to be eager to off both), Nana Tyrell is in harm zone and is pretty incompetent, Mace may be killed by Meryn or Arya, and we don't know if Randyll exists. They're in a much, much worse situation on the show. Besides, nobody takes Olenna's threats about cutting the food supplies for some reason.

I think Mace is the safest of them all, more likely Arya will save him without even realizing it when she offs Meryn.

I think the book Tyrells are in for major fall through some means tbh, they switched sides and come out on top way too many times without a scratch. Between crowning the usurper Renly, starving KL when Renly was alive, then saving the Lannisters from Stannis's justice only to murder Joffrey in a frame job that set off Cersei's dwarf slaughter and other bloodshed, House Tyrell has a lot of scheming to answer for in the game of thrones. I think they need a named casualty after all the losses every other major house has suffered.

And no way the show would prematurely cut Olenna after making so much more use of than the books did. LF's a petty guy but mutual threats and posturing is probably the closest he ever gets to friendship, he never directly moved against Varys until Varys had Ros as a double agent, and even then her death wasn't really a hit for Varys. I can easily imagine his and Olenna's partnership always being contentious. 

For some reason I am not worried about Oleanna and Shireen. Call me crazy. I don't think Shireen gets burned. I think Oleanna gets taken down several pegs and I think Margarey or Loras might die. I think people do not take Olenna's threats seriously because they know she can be bought especially if it will benefit her family.

I'm not too worried at this point. I don't think they would've given us that touching scene between Stannis and Shireen if he was going to okay her burning. I think he stands his ground with telling Mel "no" and that shot of Selyse crying is because Mel is leaving.

As for Olenna, I'm not worried about her safety at all. I think she probably succeeds in making some sparrows' lives harder.

I'm completely euchred because of the whole Stannis/Shireen thing, I'm just a nervous wreck atm... Scared as hell and I'm not sure if I want or don't want to see the next three episodes... I just feel one of them, if not even both, are dead meat soon ...

Well said and I agree that special scene between Stannis and Shireen was not done to put the fear in us she's going to die, but to reconfirm how much she really means to Stannis so that when it comes down to the wire and he has to chose between sacrificing his daughter to (possibly) save his men through Mel's sorcery, he'll choose his daughter. The only way I would think he would change his mind is if she's about to die anyways from the cold or something and I don't think they get that bad off even with losing men left and right. 

Selyse crying because Mel just got pissed and decided to go back to the wall makes a lot more sense - especially if Stannis forbids her going with her because he wants to keep Shireen safe. He knows full well how bat shit crazy Selyse is and that she'd bend to Mel's wishes in a second.

Many good points you've made I would re-iterate on:

- Olenna and Littlefinger are a great verbal sparring team much the way Varys and Littlefinger were in seasons past. They'd be fools to get rid of her or Littlefinger either one right now and will ride that pony for as long as they can. That doesn't mean either of them are 'safe' (book or show) as obviously we have no idea who makes it to endgame at this point.

- This probably sounds odd, but I actually don't want Littlefinger to die until the very end and like you, I think he will in fact be around for a long while yet. I think his chaos ladder is really interesting and to me, he's a far more fascinating villain than the tired psycho-movie-trope type like Joffrey and Ramsay. Now that's not to say the show writers haven't messed him up just a bit from book Littlefinger but I'm still rooting for him as a villain until the end game showdown.

- Selyse is a goner in my book, one way or another. They've set her up to be Lysa II, so your idea that maybe Stannis himself gets rid of her is quite interesting and one I'd get behind and support if that's the way the show takes it but I'm sure many Stannis fans would be outraged by suggesting that sort of smear on his reputation!

- Shireen will be safe so long as Davos and Stannis are nearby. Stannis just told Mel to piss off so I would not be at all surprised if she takes off for the wall in a huff after deciding whatever she saw in the fires was all BS anyways and now Jon's the real key to "Red Rahloo" (I think that's what Fire and Blood calls him LOL) which of course makes Jon Snow fans furious but hey, there needs to be some sort of catalyst in the ice and fire thing, right? 

No. Shireen doesn't deserve that sickly little maniack.
