But then again..

IKR...Ugh confusion...and why tf wasn't the "real" ciel marked....and our ciel freakin burned with brand so many questions that may or may not be answered in this arc.

He wasn't irritated tho... He was just very confused because Ciel was the sacrifice and Sebastian may be asking to himself how tf a sacrifice could come back to life lol And yes, indeed Ciel looked pretty damn dead lmao that's why that leads to think that he was brought back from death

The real Ciel WAS marked! You can see his mark in other chapters (can't tell you which one exactly tho). It is just that real Ciel wasn't complaining as much as OurCiel but in this chapter, OurCiel asks Ciel "Did your mark stopped aching?" or something like that

Yeah both of them got the mark, one of them got killed... And did the Stephen King- move to come back evil. ;_;

did you never knew demons workd like that -0- ?

In many offer and only in Offer a Demon can come out they want make deal with you but before that you need to serf them before getting something, a demon is not like angel who can come easy demons are more sealed then angels .o.. Beside you need to feed them with Hate,Hangry and not believe in god at all ir angels

Not forget in another anime as: the story of tnaja everybody who STRONG believe in god and humanty only get the Power of God, Only by Tanja she didne even believe in God or Anything that doenst Exit in the world The god only Challange her and Give her the power with only Believeing in OD WISHED.

while sabastion is a demon they have rules He caint come ut on his free will before the Offer you should by know already know that.

Sabasyion bascely needed do it that way .o. beside I think he didnt knew Our ciel Did have a brother he only Know there was 1 Ciel not 2 that why he got surpriced when there wa s a Secnd one not only that but NOBODy exspect the Bulter Knew there where 2 AS the family and Aunt

It is obvious Sebastian knew that OC had a twin, you yourself said it: He is a demon. People can not deceive demons, besides, RC WAS the sacrifice so it is more than a fact that Sebastian knew it. I you don't think so yet, then remember the body WAS laying there, in front of Sebs AND they had to CUT OPEN his body in order to take out the ring. He was just surprised because a sacrifices (someone supposed to be dead) is 'alive', fine and dandy.

Demons are extremely intelligent, ''you should know that by now''.
