This question contains ending spoilers:
At the end of the game, after the credits, you see Maurice locked up in a garage, muttering the numbers "1, 2, 3, 5" to himself over and over again.
What does this mean? I've seen a few theories:
Someone in the audio logs mentioned putting the Fibonacci Sequence into ctOS to see if [..] subliminal messaging would cause people to see the numbers. Hence, Maurice saying the Fibonacci Sequence confirms that the 'experiment' [was] a success. (source)
1235 is the license plate from the car crash when Lena dies. (source)
and another one:
I'm assuming it's a reference to 1984 and Double Speak where they talk about how easily they could convince the population 2+2=5 if they wanted. That combined with Defalt's subtitle being "twoplustwoequalsfive" leads to that. (source)
Do any of these theories have any merit? (I'd go with the audio-log one, if that audio-log really exists)
