re: The Night Of Finale Episode Prediction Thread (Spoilers I'm sure)

I think there may be a good chance that Stone did it. That obscure ending with him chasing Duane Reid in the alley...it had to be intentional that they didn't follow up on it. The writers want us to believe that Stone could tell that Trevor was lying when he watched Box's interview, but Stone already knew that he was with someone else, because he saw the whole altercation from inside Andrea's apartment. Stone kills Andrea, and is seen by Duane scaling down the tree. Duane asks him wtf he is doing, then sees his grotesque feet, and flees.

All of this will be revealed after Naz is found guilty, and the last scene will show what happened after Stone chased Duane in the alley - Stone pummeling Duane with that pipe / lug nut wrench.
