[His shoulders slump a little. It's something he prefers not to speak about at all. But he knows eventually, Percy is going to ask questions. He does owe it to his progeny to at least give some peace of mind.]

I'm not certain. I don't often make vampires, [Percy is his first in two decades.] so the sample size is too small to make any positive correlations between the old blood I was born into and the blood of my maker that brought me to the Silver Court. But you are right, I don't. Talk about it. It's complicated. I know you understand better than most the trouble with old families and legacies. Perhaps some day, I'll sit you down and tell you all of it.

[Not right now though. Right now, he's stepping into Percy's lab. He carefully puts his hands behind his back and gives the younger vampire room. However, he keenly looks over everything. There's just the smallest jutting of his chest, puffed out in fatherly pride at all the work he sees there. He wants to ask questions and admire Percy's work but he also wants to get into his office and beyond it to his own chambers.

That's my boy. Brilliant and resourceful. Since you have the means of my deliverance to my rooms, I'll have you lead the way back.
