King Joffrey Baratheon
True, but I still I can not shake that he is not their child. I can not see Ned tolerating his wife treating Jon like crap...if that was his sister's only child. One could say to protect him from Robert's wrath...I don't know. Ned didn't agree with how Cat treated Jon, but he understood and did stand up for him. He made a serious promise to his sister to protect and raise Jon as his own. In the first book, whenever he thought of Lyanna, his thoughts
always turned to Jon. I think that's more than a coincidence.
Also, in the crypts when Robert visits him, they talk about Lyanna and Rhaegar kidnapping her, but Ned never once says a bad thing about him. What's that about? This guy kidnaps and rapes his only sister, then kills her and he doesn't think badly of him? That's some ******** up sense of honor to your family.
And if Jon Snow isn't Lyanna's son, then who is he? He isn't Ned's son, there's too many time discrepancies with what has been said in the books between characters. Especially Ned and Cat.
