No. What are you doing he-here? [Slow breath, like Sebastian taught him. The tightness gripping his chest loosens its hold a tiny bit, responding to his reluctant relief at Sebastian's presence.]
I thought we'd agreed to investigate on our own first. [Ciel distinctly remembers making a case for people being more responsive to a harmless child.]
