hi i am digging your baby son adoring us video, it's absolutely cool hehe, and i am wondering about halo meanings, it's most likely not correct at all but i wanted to share my thoughts (basing on what i know from all the information you shared about aiden and his family lore so far)-
sooo i think aiden's halo is a reflection of who he is "adoring" you know - when aiden is a pup, he seems to have the exact same halo as his parents have, which would mean he once was close with them and saw them as parental figures. and later, after vis ruined everything and when question came in the picuture, aiden's halo changed - now it's hollow, and has no rays. question seemed to have no halo, so i like to think that aiden is slowly, piece after piece, losing his halo as well, most likely due to question's influence, so eventually he would be just like his new father figure. but when aiden would lose his halo eventually, as he didn't lose it on video? maybe offscreen, after killing his family - that remained part of halo could be interpreted as the last string of attachment to his family and past life, so logically after getting rid of them there would be no strings attached - not anymore. he didn't want to be associated with them anymore, so that would make sense
in the same time vis's halo seems to be interesting, as it's hollow as well, but has rays (although smaller than those seen in marianne and aster's halos) - maybe after vis revealing the secret, aiden started to internalize everything vis told him, meaning he kind of got "influenced" by his uncle, so his halo was starting to slowly lose the shape formed by his parents, and started to become more like vis's.
now about the meanings of halo elements, which i am afraid would be over-interpretation (could be an alternative for influence-shaped halo though)... filled halo would mean trust, and empty halo would mean no trust at all. not sure what rays would mean though, as both aiden's parents (and younger aiden) and vis had them. losing halo would mean turning away from light kingdom, as i am certain halos mean light kingdom and no halo means dark kingdom. what hooked me was the fact the halos looked different depending on character and the fact aiden's halo changed shape, and it was the reason why i made that theory in a first place 😅
also by the way, marianne seemed to be pretty much upset at the beginning, with baby aiden mayhaps? maybe she was just exhausted from childbirth and i am looking too much, but she seemed to be uneasy during an entire video... oh god, i have a feeling "the secret" would be somehow related to existence of aiden. i have one theory about it but i prefer to keep it to myself, at least until the secret will be revealed in comic... maybe one day i will share it though
bruh i am sorry, it turned out much longer than i expected it to be, a real behemoth of chaotic thoughts, but i love analysing and i rewatched the video 30 times already 💀 i love your work so much
