Read the meta link. Have to say, I'm not convinced; this person writes with conviction but the actual points are hinging on assumptions, which are then used as the factual basis for more assuptions. Redbeard and "the other one" appearing in close succession might mean they're connected, on the other hand, there's only so much room in a season to set up the next seson, which is always going to have multiple interconneting storylines. Redbeard could symbolise a lot, including a brother, or be a real dog that was there at the same time as a brother, or lots more. Not to say they can't be right, but to me it seems more like the very solid groundwork for a fanfic than solid speculation for canon. *shrug*
