[Is there a barely noticeable, microscopic pause at the word "seraphim"? Does Sebastian's smile widen just a fraction? Maybe. He's been hurt by angels before!1 (literally, lol), excuse him if he's not thrilled.]
It is, isn't it? [A soft chuckle, and he sounds as pleasant as ever. Still with that slightly n_n-ier smile, though.] Although I wonder if it would be bestowing false hopes about the number of seraphim present, to say it has indeed happened to others.
