Totally did not see that ending coming. I enjoyed reading this, it was actually interesting considering the Psychology class I'm taking currently (Psychology of the Offender) where we talk about stuff like this. 
 I like how Paxton and and the mystery behind who framed Rose. In the end, I really didn't see who the real arsonist was coming and I was really surprised. The actual sentencing/punishment for the real culprit seemed a little unrealistic and like they were maybe let off a little easy, but eh, I'm a psych major not a law major. 
 But I was glad that in the end of the story after they've been dating for a while they still did their pranks.
