"...and that, class, is how a grandfather paradox could potentially result in your extinction, or in other word, you'll never be born, but...you get the point." The Doctor finished his explanation of a grandfather paradox, thinking he might have given some students a somewhat splitting headache.

The Doctor looked at his fob watch. 11:59.

"Okay, class, we're reaching the end of our first class together, in which this is what I need right now." He cleared his throat, hearing as the bell rung, signalling the end of the first Universal Studies.

"But nonetheless, remember about the work I gave you. Form a group and make a story on any paradox that you've chosen earlier. See you later."

Soon, all students, well almost all of them, left the classroom, Yang staying behind for a few more minutes. The Doctor took note of this and decided to talk to her.

"So, Ms. Xiao Long. What's keeping you around? I'm pretty sure even I have some jobs to do. I need to find the Caretaker and bring him to the teacher's lounge to talk about...something."

Yang went down, walking towards the Doctor's table. She leaned on a her hand that was supporting her on the table.

"Oh, nothing too much. I'm just wondering if you're going to be at the Vytal Festival that's starting in a week. I'm sure everyone would like you to be there and watch our fights with Huntsmen and Huntresses from other places!" She squealed happily, leaving the Doctor a bit puzzled.

"I'm sorry? Vytal Festival? I don't think I had the time to read about that, because you guys came and started chasing us just because you thought we're dangerous. What's it about anyway?" The Doctor asked, a wave of curiosity splashed into his brain.

Yang tried to find the correct words to start the answer, but came up with none. So, she just lifted her shoulders and gave a goofy grin.

"Yeah, I'm sorry. I don't think I know too much as well. But I think we can go to the library together, if you want." Yang said in a bright voice.

"Thanks, but no thanks. I've got to get the Caretaker and then we need to settle some things together, and then possibly get back the TARDIS for a test fly. I'm still worried it might break down again." The Doctor said while putting his coat on.

"Well, see you later." He then walked out of the classroom, leaving Yang alone. She sighed before started thinking about something.

"How old is he again?"

Back outside in the hall, the Doctor took out a big paper from his coat that is the map of the whole location.

"Okay, where's the teacher's lounge again?" He went to look for the teacher's lounge, at the same time started moving to make sure he's not wrong.

It took a few minutes, but at least he succeeded in reaching the teacher's lounge. He folded the map and put it back in his pocket before entering the teacher's lounge, expecting to see the Caretaker there.

"Hey, old geezer, how was-" He looked around, his question trailed off. The Caretaker wasn't in the lounge.

"You're not here yet? I told you to meet me here at noon. I don't have time for this. I need to test fly the TARDIS to make sure she is still working." The Doctor went back out to find the TARDIS and the Caretaker.

It took him 13 steps away from the teacher's lounge to hear something familiar.

"Wait...is that the TARDIS? Where is it? I have to find it before anyone else started questioning about the phone box." He started running towards the direction he heard the TARDIS made noise at.

He looked left and right, turning left at some point, before the sound gets closer towards his ears. After a few minutes, he finally found the place where the TARDIS might be at.

"A supply closet? Why would the TARDIS be here? I don't understand-" The door suddenly opened, cutting him off, revealing the Caretaker, still wearing his light brown overcoat.

He looked at the Doctor. "Oh, hey, sorry about that. I need to park it somewhere so it wouldn't look weird. I mean at the rooftop? Anyone will definitely try to steal that. Although, I think some people already did try. Some scratches at the lock. And some boot prints, like someone tried to break in. And the door looks chipped a bit. Yep, definitely more than one people tried."

The Doctor was actually about to ask why would he park the TARDIS in a supply closet, but went against it. He continued hearing the Caretaker talking about how some people at Beacon Academy actually tried to steal the TARDIS.

"Why would someone tried to break into the TARDIS, though? I don't they can even fly it right. Even a time machine that looks simple can take a few hours or days to get it right." The Doctor said to the Caretaker, who listened to him and found another possibility.

"Maybe, they want the kind of knowledge that we have. Or maybe, they actually wanted to steal the information that only the TARDIS had stored. They don't need to know how to fly a time machine or how to operate it. They just need to know us more." As soon as the Caretaker said that, he looked behind the Doctor and found two pair of eyes were spying on them from behind a wall.

"Hey, you! What do you want?!" He shouted at them, the Doctor turned around, causing the two spies to run away from their hiding spot.

The Doctor almost gave chase, before the Caretaker held him back.

"Don't. We run away from problems, not get into them. Let's forget about them for now. Right now, we might have to try and tighten the security in the TARDIS. Come on."

They ran into the TARDIS, the Doctor deadlocking it to make sure no one have any more access, even with lock pick. The Caretaker ran to the console and looked up the list of the students' names that he got from Ozpin's office. He went back to the four people he suspected the night before.

"The four of you have something horrible planned on the day of the Vytal Festival. But we'll stop you, by any means necessary."

The Doctor came to his side and watched the names along with their pictures. He pointed at them.

"How would you know they would even do something like this? Maybe they're not even evil. Maybe you're just over-reacting to some teenagers, thinking they might be bad, just because they tried to break into the TARDIS." The Doctor said, not really believing his future self.

"Oh, you'll see. I mean, can't you see they just spied on us?" The Caretaker asked his younger self.

"I don't know. I can't even say who's to believe anymore. For now, if you're right, we're going to try and stop them. Together." He put an arm around the Caretaker's shoulder, who pushed it off as a response.

"No time for that. Come on, we got to prepare for the day of the Vytal Festival." The Caretaker said, both him and the Doctor walked out of the TARDIS, making sure to lock it with the TARDIS only commanded to know the TARDIS' key.

They walked out of the supply closet, looking around to make sure no one was watching them. Especially any of the four they just learned about.

"Good, no one's here. Let's go." Walking away from the supply closet, the Caretaker stopped for a few moments and looked back one last time to where the two spies had been hiding.

"We'll find you. And we'll stop you and your evil plan." The Caretaker and the Doctor then finally walked away, towards the opposite direction of where the two spies had hid themselves.

Unbeknownst to them, the two spies from earlier emerged from an empty classroom. One of them got out their scroll and called someone on it.

The scroll rung a few times before someone picked up the call. They said something to the one who answered it.

"Cinder, we might have gotten ourselves a problem."

Everyone, welcome to Volume 3 arc. We'll have two Time Lords working together to stop a certain team that might be dumb if they think they can overpower the Doctor and the Caretaker.

And before you ask why, I'm just going to say this is because I need to see what happens if I 'fix' the whole timeline.

Bye.
