I think this so called ''A'' is Jenna or Toby.To let all of you know,Jenna is the blind chick,and Toby is the smart girls boyfriend.The so called ''A'' could not have been Garet because he was killed,and after the girls found out Garet was dead this ''A'' person sent them another text.So it is not him.Oh and Garet is the creppy cop dude.It could also can be Mona.Mona is the girl in the nut house.It is getting harder and harder to find out who is the so called ''A''.I an not wait till the end so I can find out who ''A'' is.If you know more then me please messege me because i am not at good as this as my sister prplandblk.
