Thett/ bossy Tournament R1 (ASOIAF) R + L = J is most likely the correct theory.

R + L = DI will be arguing that the child of Lyanna and Rhaegar, whom Ned Stark swore to protect from Robert Baratheon, was in fact Danaerys Targaryen, and that John Snow was the son of his brother Brandon Stark and the famed Dornish beauty Ashara Dayne.At the heart of this, anyone who believes that Danaerys is the sister of Viserys does so on the sole word of Viserys. Anyone else who could verify the story is long dead, and there is considerable evidence that Viserys lied about Danaerys's childhood. Let's see what Daenerys remembers of her early life:1. A big house with:a. A red doorb. Carved wooden beamsc. A lemontree outside2. Smells of:a. Hot sicknessb. PerfumeNow, Viserys told Dany that they lived in Braavos during her childhood, which does NOT jive with what memories Dany has of growing up. The first problem is the lemon tree, which absolutely cannot grow in cold, damp Braavos, as is explicitly mentioned in the books:“Seven hells, this place is damp,” she heard her guard complain. “I’m chilled to the bones. Where are the bloody orange trees? I always heard there were orange trees in the Free Cities. Lemons and limes. Pomegranates. Hot peppers, warm nights, girls with bare bellies. Where are the bare-bellied girls, I ask you?”“Down in Lys, and Myr, and Old Volantis,” the other guard replied. He was an older man, big-bellied and grizzled. “I went to Lys with Lord Tywin once, when he was Hand to Aerys. Braavos is north of King’s Landing, fool. Can’t you read a bloody map?”The wooden beams are a problem, as wood is extremely hard to come by in Braavos, being reserved for use in shipbuilding due to its high cos. Braavos is described by Arya as being 'all stone':"There's no more wood." Dareon had paid the innkeep double for a room with a hearth, but none of them had realized that wood would be so costly here. Trees did not grow on Braavos, save in the courts and gardens of the mighty. Nor would the Braavosi cut the pines that covered the outlying islands around their great lagoon and acted as windbreaks to shield them from storms. Instead, firewood was brought in by barge, up the rivers and across the lagoon."The smell of perfume is also problematic, as Braavos is always described as smelling very strongly of brine and fish, yet Dany never mentions this.The house with the red door represents an ideal home to Dany, being a simple, welcoming place where she runs through fields of grass barefoot. This does not sound like Braavos at all, which is consistently described as a cold, grey, rainy, dreary, uninviting city of slick cobblestones, canals, mudflats and salt spray. If Dany had lived in Braavos, one would think that at least some of those aspects would be in her memory. Instead, we have a picture that just doesn't fit in to Braavos in any way, shape or form.So, why would Viserys lie? Because, if Daenerys is his younger sister, she has much more control over her, he being the clear heir to the throne. If she is his aunt, and the daughter of the man who was next in line (his older brother) there is a much bigger problem when it comes to his own claim to the throne.Danaerys is also told by Quaithe to 'Remember the Undying. Remember who you are.' A clear sign that she is mistaken about her own identity, as evinced by Viserys's lies. And, what vision was Danaerys treated to in the House of the Undying? One in which Rhaegar and Elia discuss his need to birth a third child, while he seems to stare straight at her."Viserys, was her first thought the next time she paused, but a second glance told her otherwise. The man had her brother’s hair, but he was taller, and his eyes were a dark indigo rather than lilac. “Aegon,” he said to a woman nursing a newborn babe in a great wooden bed. “What better name for a king?”“Will you make a song for him?” the woman asked.“He has a song,” the man replied. “He is the prince that was promised, and his is the song of ice and fire.” He looked up when he said it and his eyes met Dany’s, and it seemed as if he saw her standing there beyond the door. “There must be one more,” he said, though whether he was speaking to her or the woman in the bed she could not say. “The dragon has three heads.” He went to the window seat, picked up a harp, and ran his fingers lightly over its silvery strings. Sweet sadness filled the room as man and wife and babe faded like the morning mist, only the music lingering behind to speed her on her way."Prophecy-obsessed Maester Aemon also believes that Daenerys is the 'third head of the dragon', as his deathbed laments reveal:"Once he woke up weeping. "The dragon must have three heads," he wailed, "but I am too old and frail to be one of them. I should be with her, showing her the way, but my body has betrayed me.""What also leads credence to this theory is Ned Stark's guilt in the months leading up to his death. The main conflict, at this time, is his disagreement with Robert over sending assassins after Danaerys. Ned in absolutely vehement about not following through with this, even abandoning Robert, whom he thought was in mortal danger, when the king refused to reconsider. During this time, he is haunted constantly by dreams of broken promises to Lyanna. It makes perfect sense that the promise which he felt that he was breaking was one to protect Danaerys from Robert, and it also explains his all-consuming need to stop the assassination plan."When he slept, he dreamed: dark, disturbing dreams of blood and broken promises."All in all, I think that the facts of the case point to Dany being the daughter of Rhaegar and Lyanna. I will address my opponent's argument and put forward an alternative case forward for John's lineage in my next round.
