Is a Happy Ending Possible?

At present, I believe that "happiness" is not really an attainable emotion in any sort of slenderblog, (unless it's shit) whereas having the character reach some form contentment or acceptance is vastly more plausible - something I intend to use when mine is finished.
That or, yeah, you kill them off.

It's possible, I guess, to have an ambiguously happy ending, or at least an ambiguously not-bad ending. The human drama element could end happily independently of the Slender Man bit, for instance.

Slender Man could just be one problem in a character's life, which happens to suck with or without him. Then there's Alternate Character Interpretation. Did the character actually enjoy having The Slender Man in their life because it made it eventful? If that's the case his absence wouldn't really count as a Happy Ending.

I think the happiest possible ending that doesn't violate the spirit of things is a stalemate. Literally "the blogger doesn't win but Slendy fucks off."

He's an enemy that can't be killed, I think everyone reasonable accepts that. Can he be thwarted on anything other than the short term? That's the real question. Maybe a blogger does a deal with him to get him to return from whence he came, at least for a time.

Even though I'm a diehard "GOOD GUYS SHOULD ALWAYS WIN QQ" guy, that doesn't really sit well in this mythos. Stalemate is the closest you can get.

The is no real "happy ending" for the Mythos. The only happy ending is a personal one.

Your character settled his score with his personal proxy and is left by Slender Man; your character forgets that he ever existed; your character dies. All of these are approximations of happy-ish endings. Of course, these need to be kept as a scarcity. If every blog has joy at it's end, it cheapens it. But if there's ten blogs with their characters living in despair and hopelessness, it makes the happy ending seem all the more sweeter.

Of course, the Expanded Mythos/Fear Mythos has less options for happy endings.

Well... let me add my two cents here *trows 2 cents*
I think you are all right.... but trying to find a happy ending often ends with you finding 10 more ways for the character to end up screwed.
Like the thing earlier Zuckerman said that maybe the character likes being followed by Slenderman? If you play that with the amnesia angle.... he is always going to be unfulfilled until his subconscious kicks in and reminds him of
Slendy one more time and it begins again. That would be a happyish ending
but is not really tieing up the loose ends is it?
Just a thought though!
