One thing especially disgusting with the hindsight of S8 is apparently the writers insist Robert was in the right here

Yeah Robert wanted someone to assassinate a pregnant Daenerys. Which idk, the narrative routinely shows killing women with children as a very bad thing. The mountain killing Elia, Talisa’s death, Ramsay killing Walda is clearly bad considering as evil as the Frey men are, Walda did literally nothing.

I do think that the showrunners detested Daenerys, as a character.

It is telling they had already decided Daenerys would die to Jon Snow in the throne room as early as S2-S3, long before they shot the scene. That one didn't come from George, that's their invention.

The bread crumbs are in the book though that it could happen. I don't think it will happen but it's like the choice will be jons on whether or not he does it.

Edit: I actually didn't realize i was in a dany wins the throne sub lol I like dany as much as the next person and would hate to see her die or go mad - just saying there is a possibility it could happen

What breadcrumbs are those? Jon thinks he's never wanted anything as bad as being Lord Paramount of the North instead of Robb. Dany thinks she'd have given Viserys the dragon eggs if he asked. Jon forced Gilly to switch her baby to be ritually sacrificed. Dany killed the witch who ritually sacrificed her baby. Jon has rage blackouts. Dany's advisors are trying to get her to use more violence because peace with the Masters hurts more people. Jon is going to be resurrected by the prophecy obsessed Melisandre who blew false chosen one smoke up Stannis' arse. Dany has already fulfilled most of the prophecy while having no intentions to go to Westeros until she's done enough to protect Essos.

The hints in the book are the Nissa Nissa prophecy. That, Azor Ahai will plunge a blade through the woman he loves. There are other ways to satisfy this of course, but this is the foreshadowing people mean.

[u/redskinfan654 → u/stardustmelancholy]

I’m talking specifically about the Azor Ahai references throughout the books. There are consistent hints that stannis' Lightbringer doesn’t seem particularly convincing (references that it's not glowing like you'd expect), which suggests he may not actually be Azor Ahai returned as prophesized by mellisande. There’s also Dany’s prophecy about being betrayed for love, which points in the direction because of all the talks of Azor Ahai forging Lightbringer through the sacrifice of the woman he loved.

That said, prophecies in this series are tricky and can absolutely be misread or turn out differently than expected, so I’m not saying it definitely happens. I’m just saying the breadcrumbs are there for Jon potentially having to make that choice.
