My own Gravity Falls like thing?

Taking over the world/My queen?/

Bill's P.O.V

Better go check on her to make sure she is all right I thought as I walked down the stairs to see her curled up on the couch...crying?but as soon as she heard me come down the stairs she wiped away her tears and she sat up "are you alright you seem upset " I said as I slowly inched towards the couch " Yeah, I'm fine" she said trying to fake a smile as I walked up to her and tried to cheer her up so I told her my plan " Kat I have all of my powers and I want to rule the world,and I want you to be my queen so, will you be my queen" I couldn't help but say that casually I have been practicing this for a while.

Kat's P.O.V

"w-what !?" I yelled even though I could tell something inside me wanted me to do this I didn't know what it was but I could tell it wasn't good this thing was evil and it was over powering me and it took over " I would  love to " I said with an insane grin.

Bill's P.O.V

I was actually kind of shocked when she grinned  at me and she said she would but now that I looked at her eye more closely they were a darker black then normal and there was no light reflection in her eye, so this was her evil side and the thing that replied to me in the hospital, well now that I have someone on my side I will begin total destruction of this world I thought as I turned in to my all powerful demon form, but right as I did Kat's eyes became a lighter black with a glint of light as she stared at me in shock as I just stood there grinning, "well well well, looks like the good demon came back "I said as Kat just stared and I saw a tear roll down her cheek "

Kat's P.O.V
