Undertale: Fallen Angel

One Final Question

Today's onslaught of surprises fights for attention within Frisk's mind. Currently, the victor is locked between either the appearance of the skeleton brothers or the true identity of their supervisor.

W.D. Gaster, even after all of the limited information Frisk managed to obtain across their numerous playthroughs, still remains an enigma. The monster who constructed the CORE- a colossal machine responsible for sustaining an entire population, was never so much as given a passing mention from anyone save for his few remaining followers.

It was enough to make Frisk doubt if there had even been a 'Gaster' in the first place. Now finally having indisputable proof does little to alleviate their mounting confusion.

How does he relate to Sans and Papyrus? Why does no one remember him? Something must have happened. But what?

Despite their intrigue, pursuing these questions is the last of Frisk's priorities. Right now, getting home is all that matters. Even though no promises were made, that's exactly what the trio of skeletons are attempting to do with their stupendous contraption of unknown nature. Gaster promised Frisk full transparency after he was finished inputting its calibrations. From there, his helpers will oversee its progress.

While they wait, Frisk occupies one of many comfortable mattresses inside of the lab's large sleeping quarters. Despite the facility's one-for-one appearance of when they had last seen it, the difference in mood is jarring, almost making it an entirely different place altogether.

As Frisk lays down, their heavy eyes and bodily fatigue threaten to force a nap. Something the teenager outright rejects, refusing to get an ounce of sleep until they've returned home safely. Their grip tightens around the collar of their striped shirt, wondering what Plan B is if Gaster fails with whatever he's trying to do. Unfortunately, nothing comes to mind.

If the very pinnacle of scientific prowess is unable to find a solution, there is next to no chance any other monster will be able to either.

"Sorry, am I disturbing you?" Gaster's voice says from behind the bed's headboard.

Startled is more like it. Frisk hadn't heard the scientist come in. They whirl around, facing the smiling skeleton.

"No, just waiting for answers is all," Frisk says as they sit up, crossing their arms.

Gaster gets the memo.

"Then wait no longer," he says, sitting down on the pink sheets of the mattress. "Are you curious as to how exactly we'll aid in your endeavor?"

"Kind of," Frisk replies. "I know you and your helpers are going to use the machine back there. But what does it do?"

Gaster smirks.

"Why so formal? You may refer to my associates by their proper names. After all, they seem to be good friends of yours."

Frisk purses their lips.

"Yes," they say after a moment of hesitation. "They are."

"Which brings us to the exciting part," the skeleton clasps his hands and rubs them together. "Answers. Both of our burning questions finally laid to rest with the valuable insight of the other. Why not start us off with the answer to this question? How did you get here?"

"Truthfully, I don't really know," Frisk admits. "Someone showed up and attacked my family. I charged at them and then... there was this blinding light, and we both flew through this... wormhole. When I woke up, I was here."

"How very fascinating," Gaster says, rubbing his chin. "A wormhole you say? Hmm."

"I think I might have traveled through time?" Frisk proposes. "This world, it's- it's like my own but different. Is that even possible?"
