The tv series might simplify it, but in the book I seriously doubt Jon Snow is the son of Lyanna and Rhygaer.
Lyanna made Ned promise to take care of her Targaryan baby. You know, the one with silver hair and purple eyes like Targaryan's have. Ned couldn't pass a silver haired girl off as his so he went way out of his way to take the baby to someone who could care for a Targaryan baby in a place where the Baratheons couldn't reach her, Dorne. You know the place that grows lemon trees Danny remembers from her youth.
Like I said, Dany supporters are in denial. You contradict yourself. Who has the purple eyes and silver hair, Jon? Or Dany? Some do think that were twins, some would point out that there was a gap in Jon's ages. We will find out next week.
There was much in the open about Dany being Azor Ahai. But the clues are there with Jon as well but they are subtle. I ask you are open clues, the nuggets that Martin has said that people figured it and he would not change the story, that all could see would be the stuff that people would figure it out? Or the subtle ones like the star on Sir Patrek's surcoat. Not all would see that would they? But any dang fool could see the Danny ones.

Ashara went to Starfall, my friend.
House Dayne's loyalty to House Targaryen during the War of the Usurper led to the deaths of some of its most famed members. Ser Arthur died at the tower of joy, killed by Lord Eddard Stark, who was possibly aided by Lord Howland Reed. Afterward, Eddard returned Dawn to Starfall.[9] Ashara had been a lady-in-waiting to Princess Elia Martell for a few years when she went back to Starfall for unknown reasons. Given Dawn and the news of her brother’s death by Eddard, she threw herself into the Summer Sea from the Palestone Sword. Her body was never recovered. According to her sister, Lady Allyria, Ashara loved Eddard. Many believe her or the wet-nurse Wylla to be the mother of Eddard's Edited for profanity. Please do not do it again., Jon Snow
http://m.westeros.org/index.php/House_DayneSome believe her to be Jon Snow's mother, but I think people more people subscribe to R+L=J , now, especially given the clues on the show.. We will see this week, you act as if your the only one who has read the book, yet you were unable to address the blue rose. You presume much if you assume I have only seen the show. The showrunners know the ending, they know how it gets there as well.
But go ahead and believe what thou wilt, we will know Sunday. You could be right, but I doubt it. I think Jon and Dany are both important to the ending. Some people blindly support one or the other. I think her dragons are important and Jon will be the one who betrays her out of love.
