I've Seen You Grow Old

Ciel Phantomhive: 10 years old, shorter than an average eight year old, happy as can be, not what his father would have liked, and an Earl. He lives with his family in an apartment complex, and just got new neighbours. And they were rather, as Vincent would put it, "Impure, and disgusting."

Sebastian Michaelis: 5 years old, rather talk for his age, shy and somewhat depressed, not what anyone likes to be around, and he was forced to move. They're new neighbours? Well, as Vikki would put it, "I 'poe they got poor locks on 'em doors. I migh' 'ave to take a looks-y 'round 'at place, yes I migh'."
