In the novels so far, young Griff is alive. George R. R. Martin has left many plotlines open, including young Griff's. There are various speculations among fans.

Jane Eyre's author, Charlotte Bronte (Charlotte Bronte 1818-1863), died at the age of 31. Her work, Jane Eyre, described the life experience of a young woman from a farmer's family to becoming an independent woman, depicting the restrictions and oppression of women in society at that time. Charlotte Bronte's works caused a great social response at that time and were regarded as one of the representative works of modern literature. Her works reflected the prejudice and discrimination against women in society at that time, and also showed women's pursuit of freedom and independence. However, due to the conservative and closed society at that time, Charlotte Bronte's life was also greatly threatened. Finally, she left this world at the age of 31.
