I've found it.
The way out, I mean.
It's consumed me. Obsessive. Clawing through Kari's blog, the other blogs, whatever information I could get my hands on. Moving constantly. I can't see him, but I'm constantly shouldering the weight of his presence. He's here, and he's close. But I think I know a way out.
Think about how He spread for a moment. An initial exposure. It was picked up by others, and quickly, more information was generated by these others. This was released, where it was picked up again. There are three steps here:
Infection - the initial exposure to Him, or information about him
Replication - sightings, experiences - more material is created, more information.
Dissemination - the replicated agents are spread to new people to be exposed.
What with the otherworldly wraith stalking us, it's understandable that people wouldn't pay attention to the coughs and colds we have a tendency to get. The coughing. The aches.
It's the "slendersickness". He's a virus.
A memetic virus, to be exact, rather than an actual physical viron. But the idea of the Slender Man follows this exactly. It's how he spreads.
It also explains the changes and differences between accounts: they're mutated strains of the virus, changing to get around immunities and truly infest new prey, or just because of a poor efficiency in copying information.
The theory holds. It fits.
Of course, Kari gets every sickness that comes near her.
And Kari was taking antiviral medication. Introducing the idea - or the meme - of immunity. She got the symptoms - the sightings, the "sick" symptoms, even the disappearence - but she survived. She fought it off somehow.
So I've been back to her house - her back door is never locked - and I've got her medication. I've taken it.

After all these months, all this pain and heartache, all this death and horror, I've won.
He's right there, but all He can do is look on.
