Yes, there were so many foreshadowings that went abso-bloody-lutely nowhere! Just yesterday I was thinking about Snape's flight in HBP, with Harry chasing him and Snape lecturing, "No Unforgivables from you, Potter! Blocked again and again until you learn to keep your mouth shut and your mind closed!" Why didn't JKR follow up on that? Why put it in there if it meant nothing at all? I really hoped it would lead to Harry finally paying attention and learning something, but it was a red herring. At a stretch, you could call it a clue that Snape was on the right side. *sighs* What a waste.
Thank you for your support! I don't mind (well, not much) being a cup-bearer who brings balms and ointments and appreciation to those who pierce my heart or make me laugh for joy. But you know? Just getting a fic out there in public will be thrill enough.
