Everyone shoots this down but I've heard a lot of convincing theories about why Littlefinger would know. He's always loved Cat so when the honorable Ned Stark shows up with a bastard I would think he'd do anything to find out about this kid. He always keeps his cards so close to his chest and won't play them until the exact right time. Plus wouldn't he have looked into why Ser Arthur Dayne was fighting with Rhaegar. He was Rhaegar's best friend and knight.

Yup, if it affected his precious Cat, he'd be all over that. And when he said the South, I thought you could tell what he meant. It's only the Free Folk who think everything south of the wall is south. Not a Westerosi
