The plan

Jack and I were walking for about 10 minutes when I finally had the courage to mention Chico.
Y/n: tell me what you saw the day chico died
Jack : well there is nothing to say, I saw Marcus killing Chico the morning you found the body
I tried to remember the day he died and realized Marcus was with me at Jeff's that morning. Jack was lying. I had to pretend to believe him so I could found out what really happened that day.
Y/n: what an ass, can you believe he was looking at me and telling me he liked me while the blood of my brother was on his hands.
Jack: I know right, that's crazy
Y/n: i have to meet Isabella, let's walk back to school

At school with isa:
I told her about the discussion that I had with Jack and my doubts about the fact that Marcus actually killed my brother.
Isabella: I don't know Jack seems to be an honest guy I don't think he would lie about such things. Plus he was always there for you when you needed him
Y/n: just like Marcus, why would he kill Chico ?
Isabella: maybe they got in a fight just stop thinking about it
She wanted me to believe Jack was right I could feel she was lying, they were all lying. I needed to talk to Marcus.

I left Isabella because she had to go to class and I texted Marcus to meet me at the roof. When I arrived he was already there smocking. I sat next to him in silence taking his cigarette from his hand to inhale it.
Y/n: you didn't kill him right ?
Marcus: I promised you not to hurt you, I wanted the best for you, but I need to talk to you about something else.
Y/n: tell me
Marcus: the day you told me to leave your room because you thought I killed Chico, Isabella came to find me, she tried to kiss me she said that it was because of you that she and I couldn't be together. She also mentioned that she took care of that issues.
Y/n: what do you mean?- I said, my voice breaking afraid to realize what he meant
Marcus: I think she told Jack to kill Chico and to pretend it was me just so she can have my heart.
