Game of Thrones
Watering Hole
The Lannister baggage train heading back to King's Landing is stopped at a small lake when the Dothraki attack with help of Dany on her dragon in episode 7x04 “The Spoils of War”. Bronn & Jaime climb out of the water, Tyrion surveys the destruction, and Daenerys demands the captured soldiers bend the knee or be burned alive by Drogon in episode 7x05 “Eastwatch”.
