House Tarly (or: is it hot in here?)
This week, the noble house from The Reach joined the ranks of House Baratheon, House Lannister, House Tyrell, House Martell, and House Frey of having no legitimate heirs left to become the head of the House. Since Sam, who we’ll get to in the Targaryen section because of his discovery this week, was disowned before he was sent to The Wall, Randyll and Dickon end up being the last two male Tarlys -- and victims of a barbecue based on principles.
The Randyll Tarly of the books reads more honorable to a modern audience than the adapted version for the series. Book Randyll would have remained loyal to the Tyrells, who were installed as Lords of the Reach by the Targaryens (which, coincidentally, occurred after the previous Lords of Highgarden, the Gardeners, were destroyed in the "Field of Fire" battle, the historical predecessor to last week’s Loot Train Massacre). In the books, he even bested Robert Baratheon’s army in battle during Robert’s Rebellion. The show has decided that Randyll Tarly should be one of Westeros’ biggest xenophobes. He won't bend the knee to a foreigner.
