... is somewhat exaggerated!
Some concern among fans cropped up after the recent Thronecast which stated that Lord Hoster Tully (Catelyn’s father and Lord of Riverrun) was killed at the Trident, whereas he’s alive when the novels start. We’ve checked with the “keeper of the mythos” for the production, Bryan Cogman, who says that in the show canon, Lord Hoster is very much alive (but not well, being very ill) . So, chalk that one up to a small error that cropped into Thronecast’s material at some point!
