The goat's comments were pretty intelligent. He asked the same question others have asked about "Hank's Romantic Life". Namely "Where is the romance?" "Where is the woman he is going to become attached to?" and lastly "Can he make it with Wendy, who is also a Mage in growth?"
The answer to this is simple. Hank has realized that a Lifelong Partner is not going to be in his portfolio. Lady Eisenham has told him that she's over 500 years old, and Lady Elizabeth Drummond has said that she has had 5 or so "Partners" in her 500 plus years of life. He knows that his sister, despite his efforts to prolong her life will probably only last a century or so. And the Earl of March (Sir David Drummond) is easily older than all of the non Wizard Mages in the American Council. All of his contemporaries in Magic are older than he is. All of the people he is socially with have a limited "Shelf Life".
He also has seen a life lesson in Pat. Who managed to kill an early girlfriend and cripple himself with a car as a result of his negligence.
Add to this the recognition that he get's Laid often enough and with enough variety that he doesn't need to worry about the High School Courting Dance that others have to practice.
And more surprises are to come. He needs the flexibility to unencumbered by "life long" romance.
