I work at all times, Mr Stilinski. [If Sebastian's smile - difficult though it might be to see properly in the dim light of the candle he's carrying - has a hint of that slight nastiness it sometimes takes on when Sebastian is annoyed and can't openly address that... well. He sees the secrets too. He recognises his own speech patterns too.
His tone, however, is still his usual pleasantly calm, collected one.]
I do quite prefer to do so in productive ways, however. [Searching for weaknesses in the magical barrier never turns up anything at all. And Sebastian still does it, even after having been here for well over a year.]
