Hey, but if the RCMT is accurate somehow, because real!Ciel didn’t want to be separated from his brother and Vincent’s enemies manipulated him using that, then it really reminds me of Urasawa Naoki’s Monster and the Liebert twins:

Johan Liebert, who is an actual psychopath (when we’re still wondering if real!Ciel had sociopathic tendencies of his own, was manipulated or if he was just a normal kid) was a little obsessed with Anna (Nina), his twin sister, whom he literally saw as his double.
After everything they went through, she always was the most important person in his life and his behavior towards her as a result was… peculiar. From TV tropes:

and

The difference between real!Ciel and Johan is that the Liebert twins didn’t have such a fancy childhood, whereas Vincent and Rachel managed to create a loving environment for their sons.
Also, Johan doesn’t get manipulated, ever, rather he is the one who manipulates everyone whereas real!Ciel, in the case of the RCMT or even in the current arc, probably was manipulated.
However, what’s interesting is that, in both cases, the twin who turned out “okay” is the one who wasn’t obsessing over their sibling (our!Ciel and Anna), so I might be far off my mark, but I really enjoy this possible parallel between real!Ciel and Johan when, no matter if the RCMT is accurate, we can see that real!Ciel is currently not in his right mind (Agni ;_;) but still quite serious about staying with his brother.
