( great title I know)

Jaune woke up in his dorm, and noticed he seemed heavier then before. But quickly realized this was because Pyyhra was sleeping on top of him.  Jaune moves her back to her bed with the force, and hurried to the bathroom, and when he got there, locked the door and looked in the mirror. The first thing he noticed was his eyes were much oranger then before, which was a side effect of adsorbing a dark lord of the Sith. His ones were also now more black, with them now being brown, white and black. Reaching out with the force, Jaune made a small amount of force lightning and let it dance around his hands. He then went to his belt, and felt a lightsaber. Taking it out he ignited the crimson blade. Odd.

Jaune: palpatine doesn't strike me as someone who uses a lightsaber, odd.

Deactivating the saber, Jaune stepped out and was greeted with a very worried looking Pyyhra.
Pyyhra: Jaune! Are you alright!
Jaune: of course I am.
Pyyhra: don't scare me like that, ever again!
Jaune: yes mam
Pyyhra: now come on, we're going to vale with team rwby!
Jaune: all of team rwby?
Pyyhra: yeah. It's fine just don't talk to yang, Weiss and Blake.
Jaune: I'll try
Pyyhra: well come on!

They hurry Over to team rwbys dorm and knock, ruby opens the door and they come in. Nora and ren are already there, sitting on the floor.
Ruby: you guys made it! Now we can go!
Yang: yeah let's go! Wait.

She looks at Jaune
Yang: what are you doing here?
Jaune: Am I not allowed to be here?
Blake: we don't want you here.
Jaune: good thing I don't care.
Weiss: leave or will make you!
Jaune: are you threatening me miss Schnee?
Weiss: at least you have some intelligence. You know when your outmatched
Jaune smirked, feeling his inner anakin awaken.
Jauen: really? Because last time I checked it was you who lost to me in 40 seconds late time we fought.
Weiss: why you!!
Ruby: can't we please just go to vale!
Weiss: fine....

In vale

Weiss: what, would you like me to stop calling the trash can a trash can? Or the lamppost a lamp post?
Ruby: please weiss stop!
Weiss: why should I?
Anakin: because no one wants to hear you!
( only Jaune can hear the force ghosts)
Weiss: all those faunes know how to do is...
Weiss: lie!
Luke: Dont say it!
Weiss: steal!
Palpatine: if she says another word, I will personally end her!
Weiss: and murder!
Crack
Everyone turns to Jaune, who had his fists in the wall, causing a spider web like crack to spread across the wall. Jaune eyes begin to glow a horrible orange, glowing brighter and brighter by the second. His skin seems to deteriorate until it's nothing more than a shriveled husk of what it was. This was not  Jaune arc, no, this was Emperor Palpatine.
Palpatine: Do you know what happens when an insolent little girl oversteps her bounds?

Weiss despite how scared she was, didn't want to show it.
Weiss: how dare you!
Palpatine: and when that little girl just happens to be overstepping herself next to a person who she really shouldn't try to speak to. She tends to die, in the most painful ways possible.

Palpatine gets up into Weiss's face.
Palpatine: so please annoying brat, for my sake and yours.

Weiss looks into who she though was jaunes eyes. His face displayed a honest smile, a understanding smile. His tone was no different. But his eyes. Those gleaming orange eyes. They promised a world of pain and hurt, and looked crazed, yet collected and calm at the same time.
Jaune begins to walk away.
Palpatine: Dont worry, I shall return.
Pyyhra: but the headmaster!
Palpatine: I AM THE HEADMASTER!

Everyone looks at him weirdly.
Palpatine: anyways, safe travels.
And with that Jaune disappears into the night. And what follows him

Is the crazed laughter of a madman
