Forrest Gimp
He was telling his mother that he heard about rumors about her and his uncle and if it was true. But the queen however denied those rumors asking him to believe everything he hears. So the simple answer is no, he doesnt know either.
In a previous episode he made a snidey comment to his mother about the rumours Stannis spread but I don't think he believes them.
Thanks, this is what I thought the answer was, but had a little doubt about it. Really hope he does find out in the end, just before they give him a slow and painful death. Arya to stand there and do the bidding
