A bright flash suddenly envelopes the entirety of the room. When the light subsides, in its place stands a female human child and a young goat boy.
"I'm so sorry Chara. I just wanted to go back. Back to where I could FEEL again. Before I was a flower." The goat boy says.
The human frowns. "Asriel. You know I'm not..."
"I know you're not actually Chara. Chara's been gone for a long time." He pauses. "What IS you're name?"
"My name is Frisk."
"Hmm. Frisk. That... that's a nice name." Asriel begins to tear up, and turns away. "I don't expect you to forgive me."
"I do forgive you." Frisk says. "I don't know you very well, but I know that you weren't yourself. You seem like you're better than Flowey."
Asriel turns back toward Frisk and smiles. "You're right. I am better than Flowey." He pauses. "When I absorbed the souls of every monster in the Underground, I didn't just regain the ability to feel again. I can feel the emotions and Determination of everyone else. How much they care about you. How much they want you to succeed. Even though they barely know you, they are still rooting for you to pull through." He sighs. "I can't keep these souls inside of me. They deserve to be free. But first, I need to do something."
Asriel closes his eyes tightly and slowly lifts his arms, raising off of the ground as he did so. The six human souls that Asriel had absorbed emerged from his body, along with hundreds of monster souls, and another flash occurred, followed by a sound similar to the shattering of glass.
--The barrier was destroyed--
The light subsides one more, and Asriel slowly lowers to the ground in front of Frisk.
"Without the souls of everyone, I'm gonna turn back into a flower soon." He pauses. "Please. Just remember me as I am now." Asriel begins to cry. "Please."
Suddenly, Frisk wraps him in a hug. Asriel soon returns the hug, and lets out all of his tears. After their brief embrace, Asriel suddenly pulls himself away from Frisk.
"What's the matter Asriel?" Frisk asks. She notices Asriel beginning to glow, and gasps.
"It's already starting." He begins to walk away, but stops and turns back towards Frisk. "Promise me one thing. Don't tell my parents what happened. I don't want them to worry." He continues walking, and over his shoulder, he says, "Goodbye Frisk."
"Goodbye Asriel." Frisk says back. As he walks away, Asriel glows brighter and brighter, until the room is enveloped in light. Soon after, Frisk begins to hear distant voices, and makes her way toward them.
She awakens with a loud gasp on the floor of the back room of King Asgore's castle in the Underground. She is surrounded by a variety of monsters she had befriended during her time underground. Asgore, a cloaked goat monster, sits back in relief as Frisk awakens. Undyne, a fish monster, helps Alphys, a lizard-like monster, wipe away her sweat. Papyrus, a tall skeleton in "armor", hugs Toriel, another goat monster, in relief. Papyrus's short smiling brother, Sans, merely winks.
"hey kid. next time don't pass out on us like that." Sans says.
"Yeah!" Undyne adds. "Poor Alphys was sweating bullets." Alphys blushes and looks away.
"and papyrus was over here crying."
"SANS! I WAS NOT CRYING. I JUST... CAUGHT SOMETHING IN MY EYE."
"what'd ya catch?"
"TEARS!!!" Everyone begins to laugh, and Papyrus looks away and pouts.
Toriel helps Frisk up off of the ground and hugs her. "Please don't scare me like that again, my child."
Frisk just smiles. "I'll try not to." Asgore then approaches Frisk.
"I don't know what happened, or what you did, but you managed to destroy the barrier."
"I... don't exactly remember how or what happened." Frisk responds. She feels bad for lying. Asgore simply shrugs.
"All that matters is we can now return to the surface. We'll follow you out Frisk."
"Okay. I'm ready to go." Frisk says. She turns and makes her way outside, the monsters close behind. As she reaches the end, she simply freezes in her tracks.
"what's the holdup, bucko?" Sans asks.
"This... isn't right. This isn't the surface that I came from. We're supposed to be on a cliff, not in a forest." She turns around and looks at the cave they exited. "Even Mount Ebbot is gone."
Asgore examines the area. "Hmm. You're right. This isn't our world. We should be careful. We don't know how friendly the natives are."
"I'M GOING TO GREET THEM! THEY WILL BE SO SURPRISED." Papyrus runs off into the woods.
"Papyrus!?!" Undyne reaches out to grab him, but he just slips out of her way.
"well. someone has to keep an eye on him." Sans says, before walking back into the cave.
"Ugh. Do we have to do everything ourselves?" Undyne says in frustration, before Frisk and the other monsters begin running after Papyrus.
