"My bladder, mostly," he replies with a stern face. As is usually the case, though, he can't resist laughing at his own joke for very long, and the familiar wheezing sound that signifies his merriment soon fills the room. When it subsides again, he resumes "Fortunately, most of the bones they still find fit to throw me aren't much to lose any sleep over. At least, after everything I've seen and heard in my long years of service, things tend to stop surprising you too much. For a youngster like you -" he says, and points to James, "- and I've told you before to stop calling me "Sir", before I start feeling as old as I am - for a youngster like you, there might still be enough in them to start eating at you. You won't wake up screaming in the middle of the night, or even lose any sleep over them, but you'll be dragging their weight around without realizing. And before you know it, you'll have grown older - too old for your mortal coil to betray. Some people can't take too many stories. I'm not saying you're one of those, but the Light knows I wouldn't want to be held accountable for the drain on your spirit that tales of human depravity might inflict."
He sits back in his chair again, having leaned into James during his short monologue, the slightly evil look in his eyes fading again. He lets out a deep sigh. "Sorry for that. I think I'd do well to turn in after this one," he says, peering into what's left of his drink. "I respect you, son. You're a good kid. Sometimes I worry for those that have yet to be tarnished by the extent of human cruelty. Take Desmond on the other hand," he says with a short laugh, "he seems to have made the extent of human cruelty his life. You wouldn't believe the number of times it has already knocked on his door."
And at that moment, you hear a knocking sound - not on Saul's office door, but on one a little down the hall, which could only mean either of yours.
Saul tries to stare straight through his own door, utterly baffled. "Well, I'll be."
