Harry Potter and What Happened After - Sahits

"Well, fine, I'll admit that you could probably handle it on your own," said Ron, "but I'd still feel more
comfortable if somebody else went with you.
"Well, the only person that's better at me in DADA is Harry," said Hermione, "And there isn't a time
that the two of us have off."
"What about when we sleep?" asked Harry.
"I don't know about you," started Hermione, "but when I sleep, I don't go off trying to fix castles."
"I'm not talking about doing it while we sleep," said Harry, laughing a bit. "What I'm saying is that we
both sleep at the same time, in fact all four of us sleep at the same time, so if we go during the night,
when we'd usually be sleeping, than any combination of the four of us would be able to go."
Hermione thought about it for a few seconds, finally she nodded and said, "Yeah, that's the best way to
do it. But I want to plan this out. Let's take a week and come up with a plan, let's tell McGonagall what
we know and what we plan to do about it. I'm tired of going off on these dangerous adventures that no
body knows about."
"Agreed," said Harry after a few moments hesitation. He kind of liked playing outside the rules, but he
knew that both he and the people he loved would be safer if he at least tried to stay inside the rules.
At the end of the week Harry, Ginny, Hermione and Ron went and talked to Professor McGonagall
about their plans, Hermione did most of the talking.
"Let me get this straight," McGonagall said after they were done, "there is a secret room in that part of
the school that can only be accessed in times of need, and only by pacing back and forth in front of it
three times and saying what you need it for?"
"Basically, yeah," said Harry.
"And you think that the way to…fix…the problems with the school, and I'm not saying there are any
problems with the school, can be found in that room?"
"Professor, we've all seen the staircases throwing students around, we've heard the teachers talking
about how the school, 'isn't cooperating' or 'the school not accepting spells'," said Harry, purposely
using a line from the conversation that he, Ginny, Ron and Hermione had overheard a few months ago.
Professor McGonagall sighed heavily and sat down in her chair. She looked at the four Head Students
and said, "alright, I'll admit, we're having problems with the castle accepting the spells we're putting
back on it, we think it may have something to do with the fact that the spells that were on it were there
for so long, it may be that some idiosyncrasies developed to compensate. At least that's the theory we're
hoping is correct because it means that in a year or so the castle will be back to normal."
"But…" said Hermione, expecting more.
"I'm sorry Ms. Granger?" said Professor McGonagall.
"Your tone of voice suggested there was a 'but' involved in your statement," said Hermione.
Professor McGonagall nodded wearily, and continued, "But we don't think that's what's going to
happen. It is more likely that there was a few spells that tied every other spell together so that they
would all work in sync. Right now it is like the castle has two conflicting personalities. One that is for
defense, which is the one that is throwing students off stair cases, and one that is for occupation, which
is the one that is dominant right now." Hermione nodded, she understood what Professor McGonagall
was saying, and she knew that the others probably did to. "The two personalities are in conflict right
now. Professors Aquos and Flitwick think that there are probably long lost spells that tie those two
personalities together so they can work in consort."
