Estes eram rumores e ninguém sabia realmente o que aconteceu.
Por exemplo, Eddard, que na verdade estava em King's Landing quando (ou apenas algumas horas depois) isso aconteceu. Até ele pensa nisso como rumores.
Unlike his brother, Ser Gregor did not live at court. He was a solitary man who seldom left his own lands, but for wars and tourneys. He had been with Lord Tywin when King's Landing fell, a new-made knight of seventeen years, even then distinguished by his size and his implacable ferocity. Some said it had been Gregor who'd dashed the skull of the infant prince Aegon Targaryen against a wall, and whispered that afterward he had raped the mother, the Dornish princess Elia, before putting her to the sword. These things were not said in Gregor's hearing.
AGOT - Eddard VII
Se até mesmo as pessoas que estavam lá para observar o resultado imediato do ato não sabem ao certo, podemos seguramente assumir que ninguém o fez. Mas é claro que os homens de Gregor devem ter sabido, seus camaradas, possivelmente, quem pode ter tido a oportunidade de testemunhar o cadáver da princesa. E sabemos que os homens de Mountain estão propensos a se gabar de seus estupros, como fizeram com ele estuprando a filha de um estalajadeiro depois do Torneio da Mão na frente de Arya e de outros soldados. Então a palavra se espalhou naturalmente, o que podemos esperar foi especialmente rápido, já que o boato era sobre a ex-futura rainha, Uma princesa de Dorne e sua morte trágica.
Robert mais tarde ordenou um inquérito, mas foi apenas um show, ele não ia romper sua aliança Lannister, por isso não é uma surpresa que não estabeleceu nada."Wars and weddings have kept us well occupied, Prince Oberyn. I fear no one has yet had the time to look into murders sixteen years stale, dreadful as they were. We shall, of course, just as soon as we may. Any help that Dorne might be able to provide to restore the king's peace would only hasten the beginning of my lord father's inquiry—"
"Dwarf," said the Red Viper, in a tone grown markedly less cordial, "spare me your Lannister lies. Is it sheep you take us for, or fools? My brother is not a bloodthirsty man, but neither has he been asleep for sixteen years. Jon Arryn came to Sunspear the year after Robert took the throne, and you can be sure that he was questioned closely. Him, and a hundred more. I did not come for some mummer's show of an inquiry. I came for justice for Elia and her children, and I will have it. Starting with this lummox Gregor Clegane . . . but not, I think, ending there. Before he dies, the Enormity That Rides will tell me whence came his orders, please assure your lord father of that." He smiled.
ASOS - Tyrion V
Aqui, como você pode notar, Tyrion não menciona o estupro quando ele fala de uma nova investigação, nem Oberyn. Elia e seus filhos sendo assassinados eram indiscutíveis, mas o estupro continuou sendo apenas um boato. Oberyn ainda poderia ter insistido na investigação dessas acusações também, mas por alguma razão isso não aconteceu.
Entre si, quando discutiam a justiça, Tyrion e seu pai falavam apenas como se as acusações de assassinato fossem as únicas que Oberyn sabia com certeza e mesmo assim, ele não tinha nenhuma evidência de quem era o verdadeiro culpado. .
“Very well, as you ask so pleasantly. The Red Viper is not going to be pleasant, I fear... nor will he content himself with Ser Gregor’s head alone.”
“All the more reason not to give it to him.”
“Not to... ?” Tyrion was shocked. “I thought we were agreed that the woods were full of beasts.”
“Lesser beasts.” Lord Tywin’s fingers laced together under his chin. “Ser Gregor has served us well. No other knight in the realm inspires such terror in our enemies.”
“Oberyn knows that Gregor was the one who...”
“He knows nothing. He has heard tales. Stable gossip and kitchen calumnies. He has no crumb of proof. Ser Gregor is certainly not about to confess to him. I mean to keep him well away for so long as the Dornishmen are in King’s Landing.”
“And when Oberyn demands the justice he’s come for?”
“I will tell him that Ser Amory Lorch killed Elia and her children,” Lord Tywin said calmly. “So will you, if he asks.”
“Ser Amory Lorch is dead,” Tyrion said flatly.
“Precisely. Vargo Hoat had Ser Amory torn apart by a bear after the fall of Harrenhal. That ought to be sufficiently grisly to appease even Oberyn Martell.”
ASOS - Tyrion VI
Mas o estupro aconteceu, Tywin Lannister, comandante dos homens que o fizeram, está confiante de que isso aconteceu. Ele, no entanto, afirma que ele nunca teve a intenção de prejudicar Elia e ela deveria ter ficado ilesa.
His father shrugged. “I grant you, it was done too brutally. Elia need not have been harmed at all, that was sheer folly. By herself she was nothing.”
“Then why did the Mountain kill her?”
“Because I did not tell him to spare her. I doubt I mentioned her at all. I had more pressing concerns. Ned Stark’s van was rushing south from the Trident, and I feared it might come to swords between us. And it was in Aerys to murder Jaime, with no more cause than spite. That was the thing I feared most. That, and what Jaime himself might do.” He closed a fist. “Nor did I yet grasp what I had in Gregor Clegane, only that he was huge and terrible in battle. The rape... even you will not accuse me of giving that command, I would hope. Ser Amory was almost as bestial with Rhaenys. I asked him afterward why it had required half a hundred thrusts to kill a girl of... two? Three? He said she’d kicked him and would not stop screaming. If Lorch had halfthe wits the gods gave a turnip, he would have calmed her with a few sweet words and used a soft silk pillow.” His mouth twisted in distaste. “The blood was in him.”
ASOS - Tyrion VI
Mas depois, Tyrion admitiu na frente de Oberyn que o estupro aconteceu e quem foi o estuprador, confirmando suas dúvidas.
"How sad for him," said the Red Viper. "And for you. Do all noseless men lie so badly, I wonder?"
"I am not lying. Ser Amory dragged Princess Rhaenys out from under her father's bed and stabbed her to death. He had some men-at-arms with him, but I do not know their names." He leaned forward. "It was Ser Gregor Clegane who smashed Prince Aegon's head against a wall and raped your sister Elia with his blood and brains still on his hands."
"What is this, now? Truth, from a Lannister?" Oberyn smiled coldly. "Your father gave the commands, yes?"
ASOS - Tyrion IX
Então, quando Oberyn conheceu Gregor, ele estava certo e precisava apenas da confissão de Gregor, o que ele recebeu.
Em conclusão:
- Havia apenas rumores.
- Lannisters acreditava que Martells não tinha provas.
- Estupro aconteceu.
- No momento em que Oberyn encontrou Gregor em combate, ele estava certo sobre o estupro e que Gregor tinha feito isso, graças a Tyrion.
