Hmm...I get the feeling you're a frustrated fanfic writer.
Now I understand your previous posts.
I’ve never written a fanfiction scenario in my life... I was too busy studying high school and having fun in college to bother. (I however am not a big fan of teenagers, especially those going through puberty. I would have preferred if all teens, including myself at that age... I was a little brat, were frozen until they turned about nineteen/ twenty).

Ms. Rowling stated, years ago, that she'd already written the last chapter of book 7. I would guess that the last chapter of HP&tDH, as published, is pretty close to what Ms. Rowling wrote many years ago. As such, it ignores characters who were invented before it was written and does not very well fit the rest of HP&tDH. A skilled fanfic writer who had the benefit of reading book 7 before writing the ending could probably have produced something that would have fit better. Of course, if Ms. Rowling had the benefit of writing book 7 before writing her ending she might have been able to do better still.
BTW, I thought Ms. Rowling had said that Harry Potter was supposed to marry Lisa Simpson.
