The Secret of Sans is the really big chapter. The Sans = Future Frisk theory is the first big one I had about Undertale.

After making the case why Sans is a human, and must also be a future version of Frisk, my next step was to make a little Radio Play about "The Night of Gaster's Darkest Experiment."

Gaster, Sans and Papyrus are in the room, and it's clear at first that they're all close friends. And Gaster has something big planned for today, but it also seems to be bugging him.

In between Papyrus has some of his antics, Gaster and Sans talk to each other about how they're both humans pretending to be monsters. Gaster wonders at how close Sans has become with the monsters, and notes that he promised his mother to bring him home.. no matter what he had to do.

The plot twists when Gaster activates the puzzle defenses in the Core, though, trapping Papyrus and all the other monsters inside, while he begins charging the Portal with power from the Core, with the intention of creating a blast of power that sucks in the souls of all the other monsters outside the Core, giving Gaster the equivalent of the 7th human soul, and breaking the Barrier, saving humanity from a future war, and saving a select few members of the monster race for future tests.

Sans is horrified at what Gaster is doing, and argues that there must be another way. He tries to overcome Gaster with TK, only to find that Gaster is MUCH stronger than he remembered.

Gaster reveals he's already started stealing monster souls, giving his geriatric frame an energy he never though possible. It's clear that Gaster is becoming corrupted, and Sans tries to talk him out of it, then break the force fields Gaster has cast to pin Sans down as the experiment progresses.

Gaster turns away from Sans, and starts finishing his monologue, about how this is the way things has to be, then prepares to activate Option C  and genocide monsterkind for the greater good of humanity.

Sans teleports out of desperation (a Ness port) and slams into the back of Gaster, hurtling the human-pretending-to-be-a-ghost into the portal. Circuits fry, technology goes haywire, and with a scream Gaster, a father figure to Sans, is scattered across time and space.

As Sans stares in shock at what's happened.. he suddenly feels a searing pain as, all at once, he gains a boatload of Execution Points, and achieves an advanced LOVE level. A stain on his soul that will never go away.

As Sans is wallowing in despair, Papyrus comes in as the Core defenses deactivate, and tries to cheer up his friend. "You saved monsterkind. You're going to be popular now. Something.. I always wanted to be.."

It takes a while to bring Sans around, but Papyrus manages to do it when in some offhand comment he talks about Doing Things Over. And Sans suddenly realizes that they CAN go back in time, and change the story. And even if Sans has EXP now, and the True Pacifist Ending is forever locked away from him, that doesn't mean he can't go back in time and try to give a younger, more innocent version of himself, the chance to get a better ending, and avoid the mistakes he did.

So Sans resets the portal, he and Papyrus grab some Gaster Blasters, put on some sunglasses Blues Brothers Style, and warp back in time to save the future.

And after a moment, Gaster, now a ghost in truth, materializes behind them, and slowly floats towards the same portal as the screen fades to black.

Then, after the little play (perhaps I can find some voice actors willing to help), I talk about how The Halloween Hack is similiar to Undertale in several ways. Talk about the tragic life of Doctor Andonuts... and then reveal the stinger at the end, that Doctor Andonuts and Gaster are one and the same.

And then, the Epilogue "Finding Frisk".

Anyways, that's my plan so far.
