My theory in this Penumbra story; why Red did what he did

[Linux.Blue]

this wiki is accurate/official? I heard some wiki sites giving the people the chance to fill in whatever.

I keep thinking that myself when I think of the intro to Black Plague.
my idea was "Good day, good day, can you hear me?" then a pause, followed by a burst of laughter.
I haven't read the whole penumbra stuff like a lot of other people did. I read some, but after the doom 3 and reading all those PDA's, I was like, ah, I don't know if I want to read it all.
where does it really say he had cabin fever? am I not looking in the right places?
