In Season 6, King Robert Baratheon and Eddard Stark appear in one of Bran’s visions into the past. During the scene, Eddard told King Robert that Jon’s mother was a servant named Wylah (sp.) – But he refused to tell him what she looked like.

Eddard when on to say that he never told Jon whether his mother was dead or alive. However, he promised Jon that when he returned from King’s Landing, he would tell him about her. Eddard was beheaded at the order of Joffrey before fulfilling the promise to his son.

The original episodes aired during Season 1 or Season 2.

Who is capable of defeat Daenerys, 'Mother of the Dragons' and the dead Jon Snow?

Aerys Targaryen was the last to rule from the Iron Throne.

Agreed, Aerys was dethroned by King Robert and later betrayed and murdered by Jaimie Lannister, earning him the name "Kingslayer." He will most likely meet a fiery death.

Now, according to ancient prophecy, the dragon has three heads. My theory (today) is that Tyrion will ride the third dragon – And Daenerys will save the world.
