'Huh?!' Or 'What?!' would be the reaction that everyone had to Ciel's brother appearance in the manor as he stood on the stairs with you and Undertaker not far from him.

'I am the real Ciel Phantomhive, the Earl to be exact. Not you brother.' Ciel said proudly with a hand over his chest looking down at his brother, Sebastian, Baldroy, Mey-Rin, Finn, and Elizabeth as they were still shocked by this.

Undertaker then decided to speak chuckling, "My bizarre doll, my perfect one, which helped resurrect Ciel Phantomhive~" "That doesn't explain how is my brother alive entirely!" Ciel said still shocked.
