Daniel McVey - evil doppelgänger? *contains spoilers*
So all of the people present at the dinner when the initial mirror broke had an evil doppelgänger come to life and kill the person.
However what I was confused about was the brother, Daniel. One scene, where he is standing looking at his painting while the phone was ringing, led me to believe that his doppelgänger already showed up and "original Daniel" was dead. But then in scenes where he picked up the rolling oranges from his neighbour, when he came back home to find his wife (or gf?) dead and at the end when he sees his sister in this hospital and he runs away frightened, I thought otherwise.
What exactly was the status of Daniel? And if he was an evil doppelgänger, why would he run away all scared at the sight of his evil doppelgänger sister? And if he wasn't the evil doppelgänger (which seems to be the case), why was he spared?
Also, what was the point of the neighbour, Harry I believe his name was, dropping the oranges and not being able to say anything, with his wife peering from the doorway?
