Thanks for your comment! But I'm not at all sure that the influence extends that far - Dominic does seem an intriguing character, but he is secondary to Rickie, and we get Cecil's viewpoint and Rickie's, not his. So, if "Sun Slower, Sun Faster" were a direct influence, I'm sure Neville would be the hero rather than Harry. Also, though Harry does show some skill as a teacher, I'm not at all sure he is going to survive to teach at Hogwarts. My picks for the kid who will go back to teach are Neville (Herbology) and Draco (Potions). But we'll see!

BTW, I do think Snape will eventually go back to teach, if HE survives - he might not. But he will teach Defense, not Potions. Defense is his field, just as it is Harry's.
