Like King Robert Baratheon did eons ago, Jon passes by the statue of Lyanna Stark. Back in season one, episode one, Robert and his "family" stop by Winterfell, and the first thing Robert does is demand Ned takes him to Lyanna's grave. He lays a feather there, all the while telling Ned that he still has fantasies about killing Rhaegar. Ned attempts to convince him that all the Targaryens are dead, but Robert responds: "Not all of them." Boy, was he right!
