"April 21, 2008, it's been 3 years, 6 months, and 7 days since the catastrophe."
"I am Colonel Robert Neville, and this might be my last diary entry."
"Just yesterday, my most hopeful test subject died, rendering nearly three months of effort futile. Honestly, I am very disappointed. Maybe I should return to God, to reunite with my wife and daughter."
"Fortunately, I still have Sam, and luckily, I've found a new mutation of the virus."
"The newly mutated individual seems to have regained human cognitive and behavioral capacities... God, they are virtually indistinguishable from humans!"
"But they are not humans, no, seeing them, every cell in my body screams out to me, danger!!"
"They are monsters driven by the virus, more dangerous and aggressive than the living dead; they have intelligence, they have learned to use tools, they will replace us, replace humans, and I must stop this from happening."
