Just finished watching "Be Right Back" and found it really interesting.
I like how he couldn't show any emotion, but when she told him to jump off the cliff and beg for his life, he could. Maybe he tried getting in contact with someone in his final moments after the car crash.
Looking forward to seeing the second episode. Maybe it's a game concept taken too far? It looks like they're all trying to kill her, if you survive you win? Can't wait!
He was responding to her command and then accessed the relevant files/video. That was why she snapped and started screaming because she realised he couldn't ever possibly be the independent, quirky man she know with real thoughts and feelings, only an automaton with old experiences it could simulate on command.
