I have a question...for the title, I'm guessing you didn't spell "the" wrong, and intentionally titled this "Until thee End"...is that supposed to be a double meaning (like a play on words)? Like one meaning is "Until the End," as in Sebastian will be with Ciel until the end, and the other meaning is "Until thee End," as in until Ciel dies because "thee" used to be an old-fashioned word for "you." Was that your intention?
I'm sorry if it wasn't and I'm just overthinking this for no reason
"Butler.. I must ask you this were ever did you get that splendid waist coat from?" Viscount laughed as he looked to him then to his contract seal . "Yes tattoos are indeed in fashion.. but are you sure that such things are suitable for your line of work my dear fellow?"
The demon simply arched a finally groomed brow, crimson eyes seeming unamused by the Viscounts nonsenseable questions. "All of my clothing are of course made by myself, I trust no one else to get the fit correct. As for my ....tattoo...I wear gloves for a reason. It would be best if you minded your own, dear sir. Somethings aren't meant to be understood by others." with a bow the butler would simply be on his way.
