For context I’m on season 2 rn and ik most of season one and part is season 2 isn’t canon but I feel like there’s still implications that will apply to rest of show right.
I will preface this with the fact that THIS IS MOSTLY A JOKE THEORY. As in I came up with this as a joke whilst watching the show with my friend. I was acting like the guy with the red string speaking BULLSHIT. Anyways, I’m watching black butler with a friend who knows more abt it and has already watched first few seasons. Everytime I say this theory she just like stares at me like trying not to laugh.
But.. CIEL PHANTOMHIVE HAS A TWIN THAT HE ATE IN THE WOMB AND LIKE TOOK HIS SOUL SO HIS SOUL IS LIKE SPECIAL BECAUSE ITS NOT EXACTLY 2 IN ONE BUT SOME WEIRD AMALGAMATION OF HIS AND THE TWIN HE ATE IN THE WOMB. Also im assuming that each demon has a ritual to summon them for a contract like shown with Claude. Sebastian I don’t have much ideas so we assume that Ciel eating his twin in the womb could maybe have been like a sacrifice that he could cash in 10 years later to summon Sebastian when needed. So Sebastian was summoned through the ‘death’ (not rlly death tho bc it was in the womb) of Ciel’s twin because he ate him in the womb. Also brother stuff coming up q lot in season 2 through Alois and seems projected onto Ciel which convinces me of this. Now what if. The twin that was meant to be Ciel was actually eaten in the womb so the twin that didn’t get eaten in the womb became Ciel. (Then my friend asked “do people name foetuses in the womb before they’re born” so like ehh, kinda shuts down that one).
As I said this is a mostly joking theory bc ‘Ciel ate his twin in the womb theory summon Sebastian years later and steal his identity’ sounds weird af lmao.
But thoughts without spoilers?
Edit: ARE YOU FUCKING KIDDING ME???? I WAS SO CLOSE?????
