It might be real. I've met four people irl recently who believe Robb will join forces with Dany. They point to the Starks bowing to Aegon The Conqueror as proof, which they learned about in the Blu Ray histories; I must say I was impressed lol.
I heard one guy go so far as to say Dany will fall in love with Robb and defeat the Lannisters. She then makes Jorah her regent to rule Westeros while she goes to the Wall to kill the Others. When she gets there she falls in love with Jon too, and a bloody love triangle results in Robb joining the Others, kidnapping Dany, and ultimately being defeated by Jon in a huge battle.
That shit would be kind of cool, I'm not gonna lie.
