I want to talk more specifically on somewhat more obscure Arthurian tale that is very interesting in terms of Jaime/Brienne, that of Sir Gawain and Dame Ragnall. It’s also a bit of a Beauty and the Beast tale (mirroring Jaime/Brienne, because the man is the beauty, and the woman is the beast, physically, in this one!) but where Beauty breaks the Beast’s enchantment by falling in love with him, Gawain breaks Ragnall’s enchantment by holding to his promises and respecting her as an individual, which is where I think the similarities come in to Jaime/Brienne.
