no problem! it's a really important thing for ⚡️, both for her as a character since it's a traumatic experience and for her potential relationship with ✈️. the real life ⚡️, as far as i know, did not have any famous episodes about his mother. i think their lack of connection as parent and child is partly based on the famous anecdote of stablehands drawing lots because they didn't want to deal with his temper + the take yutaka quote about him wanting to see wtf ⚡️ was thinking (these two facts influence a large part of ⚡️, but you know what i mean). on the other hand ✈️ is ALL ABOUT the maternal bloodline, it's always "[the legacy of] the mother and the grandma" with him (such romantic sentiments were quickly replaced by increasingly harsh comparisons to ⚡️ and later 🧪 after the derby). what i'm saying is, basically, i think ⚡️'s relationship with her mother is cyge playing the long con and setting up a parallel between ✈️, who will definitely be obsessed with her mother in the opposite way.
because, you know? ⚡️'s relationship with her mother is viscerally bad. ⚡️ is written to be an autistic character. it's not coding, she is straight up very intentionally written to be autistic. so you can imagine just when i say this the potential issues she would have come across as a child. her mother was well meaning, but basically it all boiled down to, "i don't want you to suffer, please act like a normal kid". when ⚡️ was scolded by adults or had trouble with other kids, her mother had already given up by then, saying things like "she's always like that, just leave her to her own devices". in private it's her not knowing how to help her child, her new support card there's a conversation where she's basically begging ⚡️ to take the path of less resistance and try to be normal. i don't think her mom is a bad person, but she was not able to be a good parent in this circumstance. we find out in 🦋 (the niece) ikusei that she's a famous singer, and that ⚡️ would be attending her performances at establishments with difficult looking books, later her laptop. so it seems like not only was unable to figure out how to raise a child like ⚡️, she was probably also preoccupied a lot even though it really seemed like she loved ⚡️ and was trying her best. (i don't have 🦋, so this is based on what i've heard).
to me, an important thing is that ✈️, who doesn't understand ⚡️ whatsoever, is likely to do and say things that scratch open wounds like that. that's right. "✈️ is a presence similar to ⚡️'s mother". not only because she has a good relationship with her mother and would probably bring it up a lot, but in a more visceral sense... she probably moves the same. i don't know how to articulate it, but part of ⚡️'s trauma is that her mother and other adults never once tried to understand her, only tried to make her do and act a certain way. so ✈️ is not dissimilar. to me, ✈️ is also autistic, but in a way that's completely incompatible with ⚡️. she stuck to her mother like gum, using everything to do with that as a strict guideline. she follows the rules to the letter, too. she's very appearance obsessed, so she's constantly masking even when it's exhausting. since 🧪 does whatever she wants and still gets results, ✈️ put pressure on herself to stand out from her as a good kid. but even if she works hard, it's very thankless. it's a compounded spiral of obsession. she's got good manners so she is good with most social situations on the surface, but she's actually not very sensitive and can't read people at all. it's that kind of thing. ⚡️ has no interest in putting up a front for others on the other hand... that's the difference between them. ⚡️ won't please others because they rejected who she was and tried to change her, when all she wanted was to be understood. everything about ✈️ is a reaction to wanting to be what is most suitable for others... namely as someone who will succeed her family's racing legacy (really, a lot of it is in direct reaction to 🧪 and not wanting to be compared to her)
so she will keep trying to connect with ⚡️ without realizing her approach is entirely offputting. she also has a very specific image of ⚡️ in her head and gets riled up when it's not the way she thought. and parcae ends up being her natural enemy... i don't think it's far off to think that ✈️ may one day end up repeating something ⚡️'s mother said and things go downhill. in general having a mental script of all the "good" and "socially acceptable" things to say to others not only doesn't work on ⚡️ but will also piss her off. i said it before, but the ✈️ who hates 🧪 for being weird (even though ✈️ is also very weird just in a different way), if she grew up with ⚡️, she would probably not like her at all. but ✈️ and ⚡️ met now and became rivals, so she became obsessed with her instead. she doesn't get the hint. she only thinks "maybe i approached her at the wrong time or said the wrong thing. i'll try again later". she feels a connection to her and wants it realized so desperately, so she keeps trying. ⚡️ wants nothing to do with her tho.
✈️ is weird as hell though, if ⚡️ told her she hates her (as a final resort), she would probably be happy. ⚡️ actually thinks about her... 🥲 (i hope ⚡️ does something like this. at kawachi jockey's retirement ceremony, which was also the race where he rode ✈️ instead of other objectively better choices, take jockey said he came to hate him for foiling his three derby win streak. ofc it's said in jest but, i think it'd be a waste if this anecdote was not used)
