Dipper was shocked and gravely embarrassed about his new wardrobe. Sure he had suits, but the other clothes were largely feminine which made it seem like this was one big joke. Sadly he knew that Bill got a thrill from seeing his "amusing" reactions. He was slowly itching towards a ocean blue crop top with green short shorts which are the least feminine clothes that he could find.

"Nice choice Pinetree. Now let's get training." Bill exclaimed. He wasn't about to tell Dipper that he was itching to just take off his clothes and take him right where he just stood.  However he felt something off about Pinetree when he transported them towards the training room. Which could spell bad news if he didn't take it seriously.

"Okay Pinetree.. We have to meditate in order to see what powers you have."Bill Said.

Dipper concentrated hard to search for his powers however he noticed that he was somehow transported to an unknown piece of his mind. It was full of trees that were lit on fire in different colors which started to terrify him. 

What's Wrong? Don't you like what I've done  to this place.

Dipper turned around to come face to face with...Himself. Except he was in black and white and looked more menacing which started to freak Dipper out. 

"Who..Who are you?" Dipper Asked.

I'm Tyrone. And I'm the evil part of you.

"Evil part of me? W..What? H...How?" Dipper Asked.

Don't know. However it's important for you to lose control.

"Lose Control?" Dipper Asked. Tyrone just smiled which shower off his razor sharp teeth and started to chant.

LOSE CONTROL. LOSE CONTROL. LoSe CoNtRoL!!

Outside of his mind, Bill noticed that Dipper was starting to sweat and shiver which is never a good sign for a magic beginner. Something is wrong with his Pinetree and it's causing him to start losing control of his powers.

He...He...He!! This is amazing!! 

Bill slowly turned around to see that Pinetree had his eyes open. However his eyes turned black and he started to grow black tattoos over his body. At this moment..He knew that he had to fight this...thing and help Pinetree come back into control. 

Let's Hope that it ends well.
