Team _BSP Dorm Y/N's POV

I sat on my bed, I had a massive headache. Not just from the extreme the effects of CX-0003, but the intense lecture evil me was giving myself. I felt another bloodsurge through my scalp as I looked at the mirror displaying my reflection.

Y/N: Pyrrha's onto us, I sense it. She knows about CX-0003. And maybe it won't be long till' Ozpin also knows then it's bye bye Beacon.

Evil Y/N: Y/N, you know what you must do.

Y/N: N-no! I won't do it. There must be another way.

Evil Y/N: You are weak! You stray away from my guidance and you will be as pathetic as ever.

Y/N: I can't do it! I can't hurt her. She's my friend and... Well Y'know... I kinda like her.

Evil Y/N: Love makes you weak you fool! We have to dispose of that hot sexy body of hers.

Y/N: You're disgusting.

Evil Y/N: Ah... Don't forget. I am you Y/N, I am only as disgusting as you make me don't you get that? You need a father-figure. When she's out of the picture then we can work on getting more powerful. Remember... It's either my way, or the highway.

Y/N: Gah! Alright alright you win! W-what do we need to do first.. M-my master.

Evil Y/N: First you need to appear normal.. Put her suspicions down to a low, then we slit her throat and make her drink her own blood. Second, the effects easily wear off even with maximum dosage , you need to increase it to 300 milligrams.

Y/N: I understand. I mean, what could possibly happen?

Pyrrha's POV

It's been 2 days only and already Y/N is acting weirder than usual. He's been anti-social even to his own teammates, he's been spending way more time in his dorm room probably manufacturing more of that vile drug or whatever he's created, and lastly he hasn't been himself, I've always known him as someone who wouldn't snap automatically.

Flashback

Student: Hey man! Can you help me with this question?

Y/N: Grow a brain and do it yourself.

Later...

Female Student: Hey Y/N. I REALLY need help with my boyfriend, maybe you could give me some dating advice?

Y/N: Take him to a bar, talk, f**k the hell out of him and have some bratty kids then move onto the next one. There, like the advice? You f**king whore!

Fem Student: *runs away crying*

Flashback End

I knew it was time to take drastic measures. I need to ask Ozpin if he knew anything about the formula Y/N made.

Timeskip

Ozpin: Oh. Hello Miss Nikos. What is it you need?

Pyrrha: Headmaster, I've noticed something different about Y/N L/N lately.

Ozpin: I understand, proceed.

Pyrrha: I saw him taking some sort of drug in his dorm room. I believe drinking it may have caused him to generate a second personality.

Ozpin: You believe this 'Other Y/N' may have caused the death of his teammate Micheal Sebastian?

Pyrrha: I don't know. But it is a possibility

Ozpin: Tell me Pyrrha. Were you able to get what was in Y/N's drug?

Pyrrha: Umm I looked into his dorm room once when he was out, please don't take that in a weird way. I saw a formula consisting of Rare Blue Roses, Grimm's blood and Vale Fungi.

Ozpin: My Oum... I thought all the data from (Dad's/Name)'s experiment was lost that day.

Pyrrha: You mean his father?

Ozpin: It's a brief story so let me explain...
