Who's in control?

"Did you even care?" I ask all of the as I backed away from them "Look we can talk about this just put it down just don't do this." One of them said as they tried to get closer to me " SHUT UP JUST SHUT UP! You could have just lied to me I mean you have been lying to me " I yelled "Y-you been lying to me why tell the truth now. Why start telling the truth now?" I ask as I started crying
"Your right Kat we should have told you the truth but we didn't so deal with it I am only here because I have to I could care less." A boy with red hair said
"S-Stop it just shut up" I say as my hand start to shake with the lighter in it
"Why? Isn't this what you wanted?" The boy ask again " YOU DID THIS" a girl wearing a mask yelled at me as I drop the lighter I thought to myself. Is this how my life end? By people I don't know make me a killer? Well I guess since we are going to die I will see them all in hell . Then as the lighter hit the ground it turned to purple flames and it was only around me it trap me everyone watch in horror" What the hell is happening?" The boy with red hair said as everyone back away and for onuce I agreed with the voice in my head when They told me to kill them all. I black out and the last thing I heard and saw was screams and blood
