I don’t know if this was done but I was re-reading the Green Witch Arc when this flashback happen in Chapter 101. The more re-reading I do the more everything falls into place and I mean everything! Of course he could be mentioning Rachel, but it makes more sense if he was referring to Our!Ciel and Real!Ciel in that instance.
Also, another thing I noticed. Earlier in the arc when Ciel is poisoned, he has flashbacks to when he was kidnapped. LIKE BUD. Yana basically confirmed 2CT in chapter 90 in that arc!! She flat out spilled the beans!
It just… makes sense. The more you re-read, the more things jump out at you and you notice all the little clues and details. I’m all for 2CT. I’m excited to see how this will play out and how both our Ciel and Sebastian take to it. There is no doubt that Undertaker is involved in this too. No doubt at all.
I’m also intrigued to see how Prince Soma is going to take to this. My heart physically hurt for him. We’ve never seen him make a face like that before either. I’m afraid of how these events are going to unfold for him.
