if you were wondering why i ship Luther/Casra, this is the scene that convinced me they were a thing. a terrible thing. just look at the depth of naked hate coming from a character noted for his indifferent attitude and his lack of combat ability. Casra is genuinely eager to kill Luther--in direct, one-to-one combat!--even though he's already dead.
(my favorite ship dynamic is "enemies who stay enemies and sex is just another way they fight/manipulate each other" ๐ )
