Personal headcanon: after Thalassa spills the beans, Apollo, Trucy, Rayfa, and Nahyuta all start to consider each other siblings and generally have a good time together (even if they're often busy). Also, once Nahyuta picks up on Apollo's feelings for Klavier, he specifically tells Trucy and Rayfa before saying anything to Apollo, so that they can all tease him about his crush together.
AAAAAAAAAAH oh MAN this is so good?? all four of them go from having nobody to having a GIANT FAMILY
apollo picking up on rayfa’s habit of calling everyone a nincompoop (at the top of his lungs no less “I’M APOLLO JUSTICE AND... YOU’RE A NINCOMPOOP”)
trucy and nahyuta (and occasionally rayfa) having gossip sessions and getting burgers with auntie maya who heard burgers and refused to be left out
apollo not being invited to these gossip sessions because he’s not good at gossiping (he’s very offended) but they always bring him back some burgers so it’s not so bad eat your hamburgers apollo
trucy becoming a big sis figure to rayfa and being absolutely DELIGHTED that she’s getting to be a big sis!! showing her lots of magic tricks bc initially rayfa was?? kinda scared of them so truce shows her the magic panties and even cuts apollo in a few pieces just to show rayfa that he’s totally fine (even though he begs to differ and Does Not Like being in little lawyer pieces) and rayfa becomes totally obsessed with magic and loves mr hat a lot
also i’m starting to ship blackmahdhi so imagine apollo figuring that nahyuta has a Thing for simon and using every evil trick in the book (and also athena) to put them in as many situations together as possible, knowing that nahyuta will stammer and pout and make a general ass of himself and apollo is LOVING IT because this is revenge for klavier you nincompoop
