What is revealed here can say that it can be his twin. It’s really the only reason why Ciel looks so incredibly frightened, why Soma recognized him and why Lizzy chose to stay at the music hall.
And how the message is veiled subtly. “Who stole the candy from my tummy?” These does suggest that the candy is the ring, and it was taken from his stomach. Well, this is beginning to hint more obviously at the twin. Which I am fine with the twist as it is, as it brings a completely different kind of subtext to the story.
What did Ciel do? He probably sacrificed his own brother. And his reaction subsequently make me think that he is afraid as he is guilty, and that he had wholeheartedly sacrificed his own brother.
For this story, I won’t expect survivor’s guilt, since it is one of grey morality from the very beginning. And Ciel barely has a shred of humanity left in him, and we don’t know how their relationship had been. But I can say that the younger twin must have been jealous. Because in Victorian Era, primogeniture was the thing. And so, it makes sense why he would be jealous. He wouldn’t have been accessed to a single cent of the fortune.
He all the more suffers from asthma, which is something that has affected him quite badly when he was a child. So, what could this mean? He could have a real reason why he would have sacrificed his brother, out of fear and eventually tried to rationalize it as everything would be for himself.
And really, it does make the most sense among all the other ideas. So, I am more or less ready for the reveal of the twin this arc as it was suggested.
But I would also expect the twin to be mentally unhinged and rather unstable. And with Sebastian’s reaction, it suggest that he has died and really was revived as a bizarre doll.
But this is all my speculation and how likely it would fit if the theory is true. There is still that chance there is a completely perfectly good explanation which doesn’t include a twin(Victoria and John Brown deciding that this is the perfect chance to strike back at him, and reveals the twin.)
Or that John Brown and Victoria also has something to do with the Blue Sect(Even though that pointed to Undertaker more due to the Campaigna and the blue star liner), but I think that Victoria closing her eye to this and only bringing up now has a point, and Ciel to her isn’t of the best image.
So, I think that this chapter revealed a lot and made me think that it’s the twin theory slowly coming to life. But I don’t know, maybe there are other explanations. Maybe there is a whole new twist. But I would expect a brutal faceoff should the twins meet each other again.
