i love the scene of adonis noticing that rei was depressed post-crossroads and all the discussions of adonis being particularly clever / observant throughout the story... it really hammers home the adonis and rei parallels. both emotionally intelligent people who feel othered and who are driven by their love for humans and desire to help even strangers to the point of self sacrifice. the major differences between them are caused by adonis' crippling self esteem (which is something he's slowly but surely learning to improve) and rei being treated like a god (something that's also changing as rei allows himself to be fallible)
