Ron's POV

I was scared to actually come in to the Professor's office. I mean, this man said he sees everything so he knew we were eavesdropping on Professor McGonagall.
"Please excuse my mother's harshness. It's been tough with our personal relationship." Professor said handing us a cup of tea each as we sat down.
Hermione got straight to the point. "What is happening, Professor? Your conversation was confusing. Your mom sounded like a young woman."
Professor exhaled and ignored that remark. "Listen, I will clear things up on Mackenzie, my dear students. I hope after you see this, you will accept her as she is."
Harry decided to ask about the 'swear on the river' part.
Professor McGonagall sighed. "Yes. You see, in history, there was this river named river Styx. It is said that if you swear on the river's name, the spirit of the river will bind to your life force. If the promise is broken, you will instantly die. It is a very serious swear."
Ginny looked at her curiously. "But how can we know you are telling the truth?"
Professor McGonagall looked down sadly. "My-my dearest cousin about when I was still a child broke his promise of keeping my secret that I was a wizard to my...um...muggle family. He died on the spot but he did it to save me."
Harry gave her an apologetic look and spoke. "Professor, we are terribly sorry, but, what makes this a very important matter that we ourselves have to swear on it?"
The professor looked at us. "I will show you the truth of Mackenzie's life."
Hermione huddled up the group. "We should take the offer."
We all nodded looking up to Professor McGonagall. "We'll do it if it helps us understand Mackenzie. Why she...eliminated her father."
"You must swear that this information will never be heard from your mouths to other students but to yourselves. Unless incredibly necessary or if I had told you, you can share it. Swear on the River Styx. S-T-Y-X." She said hastily. "Say your names too."
We looked at each other and recited together. "We,-" we said our names one by one. "-swear on the River Styx that any information given about Mackenzie's life will never be heard by other students from our mouths but to ourselves. Unless incredibly necessary or if given permission by Professor McGonagall to share." After the last words, we heard a loud thunder rumble loudly even if the sky was clear midnight black.
Professor gave out a sigh of relief. "It is done, now, BRACE YOURSELVES." She raised her wand and we were surrounded by a bunch of black smoke that formed into a scene.
"You are now entering a scene," Professor said. "You shall be silent."
All five of us, including Professor McGonagall, were standing in a scene
