The Tullys give chase all the way from Riverrun. Fortunately, Brienne reminds us just how awesome she is.
Cool as this scene is I don’t think that the Tully Gally would be able to get close enough to the bluff for this to work. Also, I wasn’t completely sure what Mr. Martin meant by galley in this scene. Based on the description I imagined it was something like a Venetiangalea sottile.
