[Being a practitioner of "actions first, explanations later", not only does Sebastian not budge; he also doesn't answer one way or another (that helps so much with making you seem coherent and all there, Sebastian). Oh, he listens to what Ciel is saying, and frowns at his words... or maybe it's at his own investigations.
Sebastian pulls up the hem of one of his trouser legs to expose his ankle (there's no end to the scandalousness today). There's the ankle monitor, fitted tightly around his leg.]
Look here. [And please explain this if it makes any sense to you. Sebastian will return to the topic of Undertaker, but for the moment being this takes precedence. He raises his eyes somewhat, to confirm-- yes, Ciel is wearing the same kind of ankle bracelet. How about Sebastian just reaches out and tries to break it for Ciel (gently; he's not looking to hurt the young master's delicate little legs.)]
