Both elizabeth and tanaka already have but if by Sebastians comment either CIEL has been turned into a demon or he also has formed a contract
For Lizzy and Tanaka I have no words but I never expected this from Tanaka, that's the truth. But I'm gonna be so much more heartbroken if finny, bard and mey-rin turn their backs against bocchan. For what I understand, the true ciel was the sacrifice for the pact. I really hope that doesn't change anything but I bet that his soul isn't the true soul.
They won't, they can't cause it was OurCiel who hired them, they are not even good servants, they are good bodyguards, the real Ciel will have no use for them
FINNY, BARD AND MEY-RIN DON'T TURN YOUR BACK TO OUR BOCCHAN DON'T DO THIS TO MY SQUAD I BEG YOU
