That is when “The Battle of the Bastards” really ignited, ultimately leading to Jon pummeling Ramsay before dogs consumed him.
Unfortunately, Rickon never learned to zig-zag (why George R.R. Martin, why?) and, just as Jon Snow reached his little brother, Rickon was hit by one of Ramsay’s arrows.
In the climactic Game of Thrones sequence, Ramsay had a freed Rickon run towards his brother, as Ramsay shot arrows at him.
