That was brilliant! What a great way to get rid if Ginny, and since it was done so publically she can't hide the fact she's just a gold digger. If Ginny keeps pushing Harry could always call on the life debt she owes him from Chamber and word it in such a way that she can't go after him, or send friiends or family members after him.
I can't wait to see what's next in this and Technomage, and Betrayal.
