I haven’t read this far into the books yet (i’m still torn about whether to watch first or read first)!

However, I’m extremely curious as my theory on Jon Snow is that he is the son of Lyanna Stark and Rhaegar Targaryen. I got the feeling Lyanna was never overly fond of her betrothed Robert and Robert seemed to have beef with Rhaegar where many others didn’t. Ned refuses to speak about the mother and I believe it is because Lyanna passed Jon onto Ned uttering on her death bed, the mysterious… “Promise me, Ned”.

Also quotes such as:

“Whoever Jon’s mother had been, Ned must have loved her fiercely, for nothing Catelyn said would persuade him to send the boy away.”

However, I asked someone who is up to reading the latest books and he told me that it was some nondescript person. I googled it, but couldn’t find a definite answer and it is still open to question as far as I can see.

I could be completely wrong here, but can anyone shed some light onto this?
