A thread for people who have read the books. I think in the interest of spoiler prevention, anything that hasn't been revealed at this point in the show should still be
spoilered. There are people who are just trailing behind the show with their book reading, so I wouldn't want anything spoiled for them. At the same time, there are parts of the earlier books the show hasn't covered YET, but could still bring them in later, maybe using different characters.
I want to talk about some theories regarding the parentage of Jon Snow. This is based on speculation from the facts revealed in the first 3 books alone, so if you haven't read them, don't read this. Again this is just speculation, there isn't any confirmation of any sort.
Various characters hear various reports about who Jon Snow's mother is, and they're all contradictory and inconclusive. It has been suggested that Jon Snow's mother is actually Ned Stark's dead sister, and Ned isn't the father at all, the Dragon Prince is. That makes Jon Snow half Targaryen and one of the possible Three Heads of the Dragon. The evidence comes from Ned finding his sister lying dead in a "bed of blood", but we never find out exactly how she died. Was it in child birth? Did Ned claim the child as his own bastard, to protect his nephew from Robert who swore to kill every Targaryen he could find?
There's also the Tyrion Targaryen theory, but that doesn't hold much water with me.
