[[WMG: The Targaryen Olenna had originally been engaged to was Maester Aemon]]
* Considering how striking she must have been when she was young and how Maester Aemon still seems to have feelings for her, it would be a very sad WhatCouldHaveBeen, especially considering that their union might have actually produced a more stable, less CrapsackWorld with a sane king and a competent and intelligent queen.
** Maester Aemon is a hundred years old(in the books and his actor is in his 90s) while Olenna is a good twenty-twenty five years younger. Of course given the age difference its possible. Moreover, Olenna is quite dismissive of that Targaryen Prince and mocking. Given that Aemon's brother Aegon V, "Egg" became the last good Targaryen ruler and in the lore, he married for love but forbade his children from doing so, and the fact that Olenna is a contemporary of Tywin, at least in the show(where he's 67), its likely that Prince was Aerys II, which means that Olenna dodged a real bullet just as she ensured Margaery did with Joffrey.
[[WMG: The Martells in Season Five]]
* The Martells and the Golden Company subplots from Books 4 and 5 will be streamlined into a single whole. Doran Martell will be introduced as a secret Chessmaster who has been Varys' sponsor and financial backer(he is stated to be very rich) in setting up the Targaryen Restoration. It will be stated that Illyrio Mopatis was one of his agents, that he had planned the Khal Drogo/Dany wedding. It will be a simple and time efficient way to introduce the new character, setting and subplot. Season 4 will open with Tyrion and Varys' ship landing at Sunspear and Tyrion meeting Doran who tells him to take his son Trystane and/or Quentyn with him to Essos to bring back "our heart's desire: Vengeance, Justice, Fire and Blood". It also gives Tyrion a palpable goal, a new dynasty change will give him a pardon for his crimes and Casterly Rock and a fresh start and Doran will tell Tyrion that he owes Oberyn who died for him.
** Oberyn Martell is stated to have spent a lot of time in the East, probably on Doran's orders to establish a support base for the exiled Targaryens. In the books he worked with the Second Sons, here he worked with the Golden Company. Doran probably kept his cards close and presumably did not tell him about Varys being his man on the inside but Varys hints quite slyly to Oberyn about their connection in their conversation in the Iron Throne.
** With Arianne presumably AdaptedOut, it is likely that Myrcella Baratheon will become a kind of quasi-replacement with Doran and the Sand Snakes trying to manipulate her to taking the crown in a PlayingBothSides gambit.
[[WMG: The Golden Company in Season Five]]
* Bittersteel's Boys have been name-dropped twice in Season 4, with Jorah being a former mercenary for them and Davos recommending hiring them to Stannis.
