[Sebastian is, as always, hungry. He's no more inhibitioned here than anyone else and, were he younger and less picky about his food, or had he not been contracted to a master already, perhaps he'd be in a similar state to Yuuki right now.
As it is, he simply looks up from his floor-mopping as he notices her approaching. Huh. He can smell her desperation even from a distance. For a few long moments he just watches her, head slightly canted to one side.]
Goodness me, miss Yuuki. Is something the matter?
[The lessened inhibitions mean his tone is more curious than concerned.]
