The famous table-sharing bed-sharing quote in the first page is from the Gesta Henrici II (Attributed to Roger of Howden); I used basically the translated text from Jean Floriās Richard the Lionheart: King and Knight but abridged a bit to fit my panel flow.
Flori talks in his book about how exaggerated expressions of emotion were commonplace in the 12th century culture, and thus a level of performative behavior would have been pretty normal. On a fujo level though, I think the artifice and weirdness of political stunts and gestures in this era (The public mourning, the dramatic penances, the Cutting of the Elm of Gisors), have a kind of interesting and campy erotic nature of their own that I find really fascinating, and this particular episode feels very much in the spirit of that. . The fun thing about the relationship of these two is less about love and whatever and more the very goofy, very whiplash-inducing back and forth performances of family, friendship and foeship.
