Chapter Text
Dipper's not sure- it could be hundred of years, maybe a few thousand- when he finally gives into temptation and starts peeking into similar dimensions.
He never takes more than a glance, a small glimpse of Grunkle Stan, his parents, Mabel, his friends, and he quickly turns away before the urge to leave his world and join that one is too strong.
Mabel, a deep part of him cries out every time he glances a different world. I just want to see Mabel, happy and smiling and alive
(Thousands of years later and her loss is still a wound that never really heals.)

The feeling hits him out of nowhere one day.
It's a dark, nasty feeling that send the coldest chill up in his spine and Dipper finds that he can't ignore it ( doesn't want to ignore; maybe this means something interesting will happen around here)
Using his third eye, he looks into the world where this energy is coming from and for the most part, it all looks the same. The more he looks, the more Dipper realized that something is seriously wrong.
The timeline is off; full of cracks and kinks that, when compared to other world he's peeked at, leaves it far behind them in terms of events and years.
There's also a feeling of an absolute doom that hangs around this world that makes his stomach knot up and do all sorts of flips.
It's not a surprise that the dark aura is because of Bill Cipher.
(His blood boils just at the thought of that one eyed demon and he can't wait to sink his claws into Bill.)
The Transcendence doesn't happen, but something far, far worse is in store. The world becomes a literal Hell and Dipper realizes that this Bill doesn't merely want chaos in this world, but utter torment. If the plan Cipher has for it actually happens, everyone will suffer endlessly.
Even if it is an alternate world with alternate versions of his family and friends that live there, he can't sit and watch it fall apart (has a feeling that Mabel, Henry, nor the the triplets would let him look the other way and let a world become a million times worst than the Transcendence.)
So, he starts making plans to stop it.

The first thing Dipper needs to do is get into that world to stop Bill.
Seeing as he's a century old demon (give or take a few years), it's not too hard. Simply find a tear in the space-time and force his way thought. There's a weird sensation akin of forcing one's self thorough a space that's slightly too tight.
He comes through a portal that, after a moment, recognizes it's as the one under the Mystery Shack. Another second passes until he realizes that there are people staring at him- three sets of eyes that are aching familiar.
Stan Pines stands with his great niece and nephew- Mabel and (a very human) Dipper Pines.
And Alcor can't help but grin before disappearing as quickly as he had arrived.
