I have always hated Elizabeth until the titanic zombie arc and now I back to hating her.....

we are on the same page. I kinda solute her for her skill during Zombie Arc. But this is too much. For 3 years Ciel has protecting her for his twin sake.

it's very disappointing for me too. the Ciel that we know up to this arc has been good with her and his employees. unlike this a$$hole Ciel which seems to hate everything "Ciel" (i can't afford to call him as fake since i want to know his real name) has done for the Phantomhives. who would have known that together with undertaker, they will make OUR Ciel be the bad guy in the end.

I think Sebastian will move out of the mansion with "Ciel". if the wish for revenge is not granted, won't the contract be terminated and ended up like in the first season that he became a demon as well?

hmm... Ciel means Heaven or Sky in France. So the twin maybe named as Enfer "Hell" or Terre "Earth". But I vote for Enfer. Remember there is one chapter where Vincent said that English name was too old. I think the twin Ciel is jealous of his twin cuz he can stand up on his own. If you recall where the twin cannot accept when OUR Ciel want to open toystore. He wants Ciel to depend on him. As he watches Ciel progression all these years from the shadow something must have triggered him.

As for anime 2nd season where Ciel became a demon. I kinda don't want to accept it cuz its too cliche.

That was season 2!! And it's not canon! Also the contract was 9n the terms of finding out who did killed the family and getting revenge
