Good update, it's a pity that it takes you longer than I to update. I do hope that you found your muse and are back into the writing game again. I'm curious as to where you will go with Young Ginny Weasley here because, regardless of the plot, Harry still has a vested interest in both Luna and Ginny as a somewhat Guardian friend and it would be a shame to eliminate either of them for the greater good, so to speak. Please update soon.
Yes indeed, Harry's "saving people thing" is definitely an impulse he can't seem to control. As for "the Greater Good", he will be having a conversation with Albus on just that topic sometime around the time he gives James and Lily the gift of the truth.
