In the booksEdit
In the A Song of Ice and Fire novels, Prince Trystane is the youngest son of Prince Doran Martell, the ruler of Dorne, and third in the Martell line of succession. He has olive skin and straight black hair. He is two years older than Myrcella Baratheon, making him about 12 years old when they are betrothed.
The casting announcement for Trystane in Season 5 describes him as the "heir to Dorne", even though in the books he has an older brother named Quentyn, and his father's eldest child and heir is actually his daughter Arianne. This may mean that Quentyn has been cut from the TV series.
It still isn't clear if Arianne exists in the TV continuity or not. She is a major character and even a POV narrator in the books. On the other hand, in the books Arianne is furious that her father is treating his son Quentyn as his heir, despite the fact that under Dornish law she should inherit ahead of him. Later she discovers that this is because her father wanted to keep options for a vital marriage-alliance open, but he never thought of this as brushing Arianne aside.
More worrisome is that the TV series has actually never established that Dorne follows equal primogeniture, unlike the rest of the continent. In stray mentions throughout Season 4, when the TV series could have introduced that women have an equal chance of inheriting lordships in Dorne, they avoided it. A "Lord Blackmont" appeared in the Season 4 premiere, when in the books House Blackmont is ruled by a woman. When Oberyn recounts to Tyrion how he traveled to Casterly Rock when Tyrion was a baby, he says that his father took him on the trip - while in the books, it was his mother, the Ruling Princess of Dorne. Indeed, Dorne's equal primogeniture laws are one of its most prominent cultural features, setting it apart from the rest of the continent - as well as directly tying into Myrcella Baratheon's major subplot in Dorne, as Arianne hopes to press the token excuse that under Dornish law, Myrcella would inherit the Iron Throne ahead of her brother Tommen.
A major point standing against an omission of Arianne is that the only dialogue which previously mentioned Trystane (Season 2's "What is Dead May Never Die") described him as Doran's "youngest son" - indirectly establishing that TV-Trystane isn't an only child, and at the least, that Doran has another son who is older than him, so TV-Trystane cannot be the "heir to Dorne". So either the character description is misworded, or the TV series will have to establish an internal retcon with facts stated in Season 2.
Elio Garcia of Westeros.org suspects that the casting description of Trystane is simply mistaken, pointing out that he was earlier described as Doran's "youngest" son, and also that the casting description said that Tywin had arranged Trystane's betrothal to Myrcella, when it was actually Tyrion who arranged the betrothal (though Tywin subsequently supported Tyrion's action when he heard about it). Elio went so far as to reach out to his contacts at HBO to determine if this was simply a mistake by someone in the HBO PR department, and he did get a response, but it consisted entirely of a terse "no comment". Elio stated his belief that while he is somewhat nervous that there has been no mention of Arianne yet (or the Greyjoy uncles and other Northmen bannermen who appear at this point in the books), the SDCC casting announcement was in no way meant to be comprehensive, and as of yet he sees no specific reason to believe that Arianne has been outright omitted from the TV continuity.
