Team RWBY arrived early in the morning.

The Doctor was sitting at his desk, wearing pair of headphones and reading a book titled The Worshipful And Ancient Law of Gallifrey. He looked up when he saw the girls entering.

"Ah, good morning Team RWBY! How are my four favorite students doing today?" he smiled while taking his headphones off. The smile faded when he saw the girls`expressions. "Is there anything wrong?" he asked, worriedly.

"Um...professor..." Ruby said nervously. "We...want to return this to you." She held out the metal cylinder.

The Doctor instantly turned pale. "Wherever did you find this?" he demanded, taking it in his hands.

"We...um...ah..." Ruby stuttered.

"We sneaked into your classroom four days ago to investigate who you are and found it." Blake spoke up.

"Please tell me you didn`t activate it." the Doctor said anxiously.

The girls` faces explained everything.

"I see..." he slowly became serious. "I was hoping it wouldn`t have to come to this, except it seems I have no choice..." he started reaching inside his pockets for something.

"What are you talking about?" Weiss backed away.

"I`m sorry, only I have to wipe your memories..." the professor stood up with his sonic screwdriver.

"What!?" the girls exclaimed at the same time.

"You heard me. That metal cylinder was one of my research materials I use for teaching preparations. Unfortunately, it can also be used to look up some...'classified information' about things best left unknown. You`ve found too much about my true identity and I must erase everything you saw."

"You`re not erasing anything of mine!" Weiss drew her rapier.

Blake and Yang also readied their weapons.

"You guys, wait!" Ruby stepped between the Doctor and her teammates. "We should all just calm down and try to - "

"Good morning, Professor Doctor! I - what`s going on!?" Jaune and his team walked into the classroom and halted.

There was a short silence.

The Doctor sighed and lowered his screwdriver. "Team RWBY, come to my classroom at dusk and I will explain everything. For now, please take a seat."The four girls lowered their own weapons and walked slowly towards their seats. Team JNPR gave them curious looks, only nothing was said.

"Ah" the Doctor returned to his old eccentricness. "Tomorrow is the last day of Special Hunter Studies. There will be a final exam to assess on what you`ve learned during my time here. I would normally give you a written assessment, only Ozpin contacted me last night requesting I give a...'special practical exam' to you young children. Therefore, I will be facing all of you in combat as a test."

The two teams blinked.

"Yep, you all heard me. I will give you more information tomorrow before the exam. For today, I would like to give some final advice on becoming guardians of Remnant in the future..."

He smiled.

The Doctor entered Professor Ozpin`s office in the late afternoon.

"Ah, Doctor. Please take a seat." the headmaster indicated towards a chair before his desk.

"I received your message, Ozzy." the Doctor stared at a chessboard on the table. "You want to have jelly babies with me?"

"No." Ozpin answered, smiling mentally at his nickname. "Would you care for a game of chess as we talk?"

"Would I? I practically invented chess! Ah, no, except I knew the people who invented it. Quite obnoxious they were, until the end..." the professor muttered. Ozpin noticed a quick expression of sorrow passing his face, before it disappeared.

"Fine then." the headmaster waited for the Doctor to make the first move."Yesterday a Dust shop heist was stopped under strange circumstances. You wouldn`t happen to know anything about it, would you?"

"Who, me?" the Doctor tried to look innocent. "I`m only a ordinary traveling professor who happens to be a member of Hermits United, I wouldn`t know anything about stuff like that."

Ozpin moved first and stared at the professor quietly.

"Oh, sure. I might had something to do with it." the Doctor admitted. "The game is afoot. You wanted some of my assistance, I decided to buy you and your allies some time, metaphorically speaking, by temporarily preventing the other side from gathering enough Dust for their dastardly plans. The Queen still has her pawns in the game."

Ozpin raised his eyebrows when the professor mentioned this. "Thank you for your aid. It appears your title of the Blue Sage is greatly earned."

"I never understood where the nickname came from." the Doctor moved his piece. "The title 'Blue Sage' is actually a poor translation from the ancient language the first humans used for me. The proper name is 'Father Time'."

There was a moment of silence while the two men continued their game of chess while thinking of what to say.

"I will be attending Team JNPR and Team RWBY`s final exam tomorrow as an observer." Ozpin finally moved his king.

"Oh, please. Be my guest, everyone wants a piece of the cookie!" the professor became somber. "Speaking of Team RWBY, those girls have finally found out about my true identity."

"Ah..." Ozpin responded, taking in this situation. "I did ask you before about them."

"It was my own fault, really. Should have done a better job at hiding." the Doctor confessed.

Ozpin made his move. "Check." he declared with his black queen piece.

"I don`t think so!" the Doctor quickly moved his white rook to defend the king. The two men continued their game quietly.

"I`ve been wondering, what would do you after Beacon?" Ozpin asked finally.

"Oh, you know. Continue traveling around like a hermit, giving people my aid, and generally being a good old lunatic."

The headmaster nodded, then continued. "The world is quite unforgiving out there, as the most brilliant lights would cease to burn over time. I hope you will not become one of them."

"Oh, you shouldn`t worry about me, I`m presently the single most dangerous being in all of Remnant." the Doctor smirked. He had faced far worse before on his adventures.

"I wouldn`t be surprised." Ozpin gave a rare laugh. There was something strange about the Blue Sage, who carried no weapons except was presently being the most dangerous person known in history. He made his final move using the black queen. "I believe this is checkmate. I win. "

"No..." the professor moved his white knight. "This is checkmate."

Ozpin examined the chessboard then sighed, acknowledging his loss. The Doctor was the first person to ever defeat him at chess. He was truly a brilliant man, greater than the headmaster himself. "Our meeting is over. I will see you tomorrow for the final exam. Goodbye then."

"Good-bye, Ozzy." the professor stood up and began walking out.

"Oh, Doctor?"

The professor looked backed at the headmaster, who had a hesitant expression on his face before asking quietly: "You knew the white rose?"

The Doctor gave a sorrowful smile. "She was the real reason I became known in this world as the Blue Sage."
