"What the hell are you doing out here, Fred? Fred, if you're real, you better tell me right now!"
Robert screams this at Fred the mannequin who is always at the DVD store where Robert put him. Now Fred is in the middle of the street. This quote underscores Robert's isolation, loneliness and inability to discern what's real from what's not. It's a moment when his mind feels like it is cracking.
"He had this idea. It was kind of a virologist idea. He believed that you could cure racism and hate... literally cure it, by injecting music and love into people's lives. When he was scheduled to perform at a peace rally, a gunman came to his house and shot him down. Two days later he walked out on that stage and sang. When they asked him why - He said, "The people, who were trying to make this world worse... are not taking a day off. How can I? Light up the darkness.""
Robert quotes Bob Marley in a story he shares with Anna in his home. It's a story about why he continues to fight to find the cure for the virus, and it has become a beacon of fire that calls out to him in his darkest moments demanding that he continues to work to discover an antivirus because the world cannot be taken over, it must be taken back.
"You can't go running into the dark."
Robert says this to Sam, his German Shepherd after she's run into a building full of the infected. It's a thematic statement he is making that's both literal and figurative. She can't go running into the darkness because that is literally where the infected protect themselves from sunlight during the day. And it also means when one ventures into darkness there is greater opportunity to be lead astray if one doesn't have the light within them.
