The One Thing Fans Totally Don't Want to See in House of the Dragon
Actually, there are quite a few things that fans don't want to see in House of the Dragon.
Some of those things are highly improbable hypotheticals, like Larys Strong surviving. Others are events which play such a major role in the narrative that they are inevitably going to be in included, yet people don't want to see them anyway, for obvious reasons, like Blood & Cheese incident, which we've already covered.
Yet others are adjustments to the book narrative, which appear probable, such as merging Hugh Hammer and Ulf White into a single character (to explain, these two did not have distinct enough roles and personalities in the book).
Yet as voting on Reddit suggests, the one thing that the fans would hate to see above all is the eventual fate of Unwin Peake.
Wait, you might ask. Who is that Unwin Peake guy? And why the book fans hate him and don't want anything good happen to him?
Well, Lord Unwin Peake is a character who is yet to appear in House of the Dragon. And to sum him up briefly, he is the very image of a slimy, treacherous schemer. After joining with the Green party, during the actual war he distinguished himself by nothing, except scheming and murder aimed at fellow Greens. But that was not the part which people hate.
Unwin Peake is hated because after the war he was somehow offered the place on the council of Aegon III's regents, then somehow managed to dominate that council, then named himself Hand of the King and Lord Protector of the Realm, staffed every important office in the capital with his relatives and supporters, and pretty much ended up as the real victor of the war.
And while his reign was fairly short-lived, he got away with everything, including having several people who were in his way die under suspicious circumstances.
In short, imagine a character as shady as Larys Strong, except without much in the way of actual, demonstrable cunning and competence, appearing almost out of nowhere to reap all the rewards, after all the heroes kill each other.
The only consolation to the fans is the fact that Unwin's ascendance only takes place after the time period that the show is likely to cover, so his character might possibly be written out of the show entirely.
