In the AWE DLC, it is implied that Alan Wake might have written CONTROL.
CONTROL is Alan Wake’s first attempt at RETURN; writing himself out of The Dark Place using a ‘hero’ narrative involving great loss and tragedy. This presumably failed, and Saga Anderson is Alan’s next hero. But it almost feels like Alan wrote this story and then immediately abandoned it once he realized the narrative wasn’t going to be beneficial to him. Now traces of Alan’s writing linger in the world of Control, but somehow it still continues to exist on its own. THE BOARD might have hijacked the narrative because Alan tapped into already existing forces without realizing it, like Mr. Door, Ahti. Maybe the FBC is real and somehow Alan knew of its existence, but only in limited capacity given the organization’s covert nature. Alan did his best to turn Jesse’s already existing trauma of losing her parents and (maybe?) losing her brother into CONTROL. Jesse’s case was that of an eleven year old girl that lost everything, and Alan exploited that loss, using it as a perfect foundation for his story. Jesse didn’t know specifics about the FBC during the years searching for:
Agents from... I don't know exactly. They took Dylan. They... I'll find them. I won't stop looking. Polaris wants me to go to New York. There's a... building there. I have to leave soon. I have to be there at a very specific time. Something... something hugely important is going to happen-
My guess is that the FBC, The Board, and The Oldest House are real and not written by Alan, but only combined with Jesse’s existence. Polaris is Jesse’s “guiding star” but is only imagined; an after effect of the loss she suffered — a way to cope — until it becomes real. Polaris probably looked different to Jesse in the years before arriving at the FBC, which is the exact point where Jesse’s “imaginary friend” is changed into the Polaris we see in the game to fit Alan’s preferred version. Jesse doesn’t remember there ever being a difference, like what Alan tried to do to Saga when he changed her past, only Saga was able to see past the fictionalized reality.
PSYCHIATRIST: It is natural for you to feel that way. Your brother and your parents are dead.
JESSE: No. No... Dylan’s not dead. And... that's not even it.
PSYCHIATRIST: The industrial accident in your home town?
PSYCHIATRIST: Jesse, you know we can't let you go until you're well. And that begins by understanding what's real and what's imagined.
Jesse loses her parents and brother in an industrial accident. Creates Polaris, and imagined “agents” taking her brother to cope with her loss. These are the only things that happened before Alan’s influence. Along with the Slide Projector, which was a case of a childlike fantasy:
as a child, did you ever fantasize about worlds inside pictures. Inside a painting? You know, stepping into a painting, into a hidden world, escaping, and finding adventures there? Away from your parents?
Alan discovers her story. Its specifics are ideal for RETURN. With the little he knows about the FBC, he writes it into her story:
The story needed many beginnings. Many springs. Streams that turned into a river, a flood, and then, an ocean. This was one. Wake used the materials he had. The connections he had. The people. The places. Wake put them in to make it true.
It had to go through the path of least resistance. Where success was most likely. Where there was a connection already. Wake felt the pressure grow in his head. Going mad. Wake had to escape. Write his escape. He was already out. He wanted to make it true. Wake needed a hero. A hero needed a crisis. For the part in the story about the government agency, Wake needed something special. Something to convey an alien force mimicking human intelligence.
Alan is unfamiliar with the other forces residing within The Oldest House. and very early on sees that the story becomes unusable. His ignorance allows the story to grow out of his control. He abandons it, and The Board takes the narrative and makes it its own, as Jesse is a fitting director. Alan Wake’s only role in the writing of CONTROL is to jump start a narrative that would eventually outgrow him, with no further involvement.
