Demon siblings crack theory
Around 3 am, I woke up with a bothersome feeling... I might have an explanation for why Sebastian and Modri's demon "look" so similar but behave so differently.
Until now, I had blown off any ideas in the fandom of Sebastian "having a twin" as a completely ridiculous crack theory, but now I feel as though I should consider it (or at least the idea that he has a "brother") as a feasible (yet still crack) alternative to Sebastian and Modri's demon being one and the same.
It's hard to define what makes two demons siblings, let alone twins, when they are shapeshifting swirls of inky goop... other than perhaps the mere fact they are "born" around the same time, have similar physical features, or function within basic constructs that have similar properties.
Examples might include (but not be limited to):
First existing within a certain timeframe of each other
First being summoned into the human realm within a certain timeframe of each other
Both springing forth from the same pre-existing source or location (and I don't simply mean Hell)
Both being made of the same materials (maybe not all demons in the Kuroverse actually have this goopy quality)
Both following a particular set of basic rules (defined as something completely separate from their aesthetics)
Both using the same or similar contract seals
What finally made me seriously consider the wild possibility -- what basically woke me up so early this morning -- is the mere fact that Modri's demon keeps being shown with stacked eyes on its right side... but ch225's cover art shows Sebastian with certain parts exposed "for what they are" beneath the human facade, and one exposed feature is stacked eyes on his left side.
I don't want to go quite as far as suggesting they could actually be mirror twins (like our earl and real Ciel), but I do find it interesting that Yana-san has made the conscious (and I do believe it's conscious) decision to reverse the placement of this distinctive feature.
If she had wanted to emphasize them being the same demon, she could have reversed the image for the cover of ch225, so that we would have seen this:
Therefore, I feel like she might be trying to say they are not the same... but are very similar for a specific reason.
Even the cover art for ch226 makes me think Sebastian could be pondering whether his own sibling is the one who had a "dalliance" with Modri.
I've seen this cover art described as showing both our earl and Sebastian bored by Modri's tale. But what if our earl is the only bored one here? If even he is just bored; he could be uneasy. Sebastian, on the other hand, seems downright pensive. Does he now recall the contract but not the name or face of his accuser? Or does he maintain that it's not him while getting the uneasy feeling he knows which demon it is? ...And why they are getting confused for each other?
I'm also reminded by this ch226 cover art that neither of them has lit their cigar yet. Once Modri once again accuses Sebastian as being the demon from his own past, our earl's quickest way to clear things up might involve ordering Sebastian to spin the wheel next. Besides, Fairchild, as the game master, might insist that no arguments break out until each player has taken their turn.
Thoughts??
