Soma goes to Agni asking for something that clearly would require an adult or money or whatever.. Agni is like "..Ask your mother, Prince" and thus Soma is SWEATING... W-Which one???? Sebastian or Mey...
Actually, I think that would be an effortless decision! While Mey Rin puts her foot down when need be—she won’t let the prince go gallivanting off if doing so would put him in harm’s way—she’s the type of mum who cheerfully buys him that large bag of candy he begged for at the sweet shop, or lets him throw a sleepover at the townhouse for the other Kuro kids on a whim. Sebastian, on the other hand, is easily the strictest of Soma’s three parents, regardless of her pronouns at any given moment.
“I wouldn’t have to play disciplinarian this often if the two of you didn’t coddle him so much!” she scolds her partners.
Therefore, if Soma wants to take O!Ciel on an impromptu elephant ride through the grounds (they won’t crush any fences this time, he promises!), he’s infinitely more likely to wheedle maternal permission out of Mey…hopefully far out of demonic earshot. 😉
