Albus and Rose were more doubtful than anyone else present there. Even the possibility of the existence of such powerful magic was strange to them, in any worlds. The silence was broken by McGonagall.
"It could be anyone, most probably one of the professors. I could get a clarification on that side. Or it may be even Miss Granger herself, unleashed the magic unconsciously at a point of emotional breakdown. There are many such reported cases."
"It's a possibility. Since it's not a commonly practised way of defence, Aurors might not be aware of it. And students couldn't perform such an advanced act. It requires fine practice. The one who could perform such a complex piece of magic is definitely an incredibly gift..."
She became dumbstruck, once before she could finish her words as if she figured out the answer she wanted. Harry could read that from her eyes, and he gives her a sharp look of warning. Hermione realised the hint in his look and spoke.
"Professor, children will be tired. Can you arrange someone to lead them into their respective places? So they could get enough rest, for tomorrow's classes."
Professor McGonagall nodded silently as if she too has realised the tension developing in the room.
"I could help with that. It would be nostalgic to have another visit through these corridors of Hogwarts. Those beautiful memories." Said Harry with a smile.
"Definitely Mr Potter. Miss Granger and I got some ministry business to deal with" said McGonagall, observing on the Aurors inspecting the unconscious old man few distances apart.
"Yeah, we've got many things to discuss."Said Hermione, but her voice was much more official than before.
Harry give an affirmative node for once, and lead Albus, James, and Rose out of the Hall. Though they were sure that, Harry and Hermione were deliberately concealing something from their knowledge.
Rose gave a glimpse toward Hermione, before leaving the hall. She was having some sort of discussion with McGonagall.
Once they reached far away from, great hall. Harry started a talk.
"Albus, I've got a present for you," said Harry, while taking out a parchment paper from his robes. "I suppose you already know the rules. And never let your mom know this"
"THE MARAUDER'S MAP. HOW COME YOU DIDN'T' GIVE IT TO ME? HE IS YOUNGER THAN ME." James was unusually loud. He seemed disappointed.
"James, you've got an invisibility cloak to roam around in the night. What should poor Albus do."As Harry said with a twisted smile, Rose and Albus give a look of surprise at James? James was quite discontented at the big reveal of his secret, so he doesn't speak for a while.
"Uncle, That one. I mean the one who cast that magic..." Rose was interrupted suddenly by Harry.
"I know where you are getting to. But believe me, it won't be a menace. It has got nothing to do with any of the onsets happened. Hogwarts is the safest place in the entire country. You've got nothing to worry."
"So was the ministry," She thought but doesn't want to annoy Harry by an open argument.
Everyone kept a meaningful silence for some while, even though everyone had their own unanswered questions in their head. They won't be denied from the answers once they want it madly. But the real question is whether they could accept the consequences.
Secrets may be tempting, but comes at a certain cost and some secrets must be protected. Harry had learnt it from his own past, and everyone will.
