(PLEASE NOTE: I feel I need to point out that I write this story with the correct fonts, including the font for your newest character in this chapter, buuuut…. Fanfiction doesn't keep these fonts, so I italicized this to show he isn't speaking in a normal manner that nyssa would initially understand. So bear with that. Even though you can read his font, as I write this I can't because its not exactly in english, and nyssa doesn't understand it at first either.)
Nyssa smiles as she twirls her umbrella, sending water droplets flying. She closes the umbrella, then puts it away with the others. As she continues on, she hears music gently playing from a statue up ahead. As she walks past she hums along to the tune. She hears talking, and peaks into the piano room to see Undyne and Shyren.
"That's right! Ha! You're getting really good at playing the piano!" Undyne says with a big smile. Shyren sheepishly smiles back at her. Nyssa continues on.
"It's nice seeing them play again." Nyssa says to herself. "Everything is finally right… I really hope I can protect this." She continues her slow trek through Waterfall, until she spots a telescope that makes her smile. "That annoying thing." She shakes her head. "I still hate Sans for that." She walks on, laughing quietly to herself. She starts humming, and closes her eyes for a moment. When she opens them again, she stops walking. "Did… Did something change?" She looks back behind herself, then forward once again. "It seems… longer." She walks down the hallway, and stops again in front of a doorway. "This is… New." She peaks in, and sees a black figure in the middle of the room. It looks at her. The face is broken, and stuck with a shattered smile. Nyssa's heart stops for a moment, but she walks in. "H-hello."
"...HELLO..." The man speaks as his hands move, however the sound is gibberish to Nyssa.
"Uh, I… I didn't… U-Under…." Nyssa struggles to speak. "A-are you okay? Wh-what are you d-doing alone?" He doesn't respond. Nyssa hesitantly raises her hand as her heal button appears in front of her. The green light reaches out and covers the man. He looks at her in surprise. "S-sorry. I thought it wouldn't hurt to heal you." She watches the cracks in the man's face shrink, but the light disappears before he's made whole. Still, the man has regained more of a normal shape. "It… It didn't…" Nyssa frowns. She hits the button again, and once again the man becomes more whole, but the light again vanishes without completing the work.
"PLEASE, WAIT A MOMENT." He continues to move his hands as he speaks, but still, Nyssa doesn't understand him.
"I wish I knew sign language." Nyssa sighs. "I-I'm sorry. I don't… I don't understand what you're saying. The man pauses, then he holds his hand out like Nyssa does. "You want me to keep going?" He nods. "Alright. Whatever is wrong, I can fix it, even if it takes a while." She holds her hand out again, and again, and again. After several healing sessions the cracks are all but gone. Nyssa is breathing heavily. "Wh-what in the w-world is w-wrong th-that it t-takes so m-much?"
"IT'S A LONG STORY." Nyssa pauses. This time, his words aren't as muddled to her. She looks into the man's eyes.
"Uh, I… I think I can, m-maybe, understand you."
"THAT IS GOOD. YOUR ABILITY TO HEAL IS VERY USEFUL. EVEN UNDER SUCH STRANGE CIRCUMSTANCES AS MINE. WHAT IS YOUR NAME?"
"My name?" He nods, and she smiles. "Uh, m-my name is Nyssa." She holds her hand up. "What's yours?" Suddenly, before she touches the button, her hand is yanked to the side.
"his name is gaster…" Nyssa looks to see Sans holding onto her wrist, glaring at Gaster. "i thought i was done with him, but i guess it was only a matter of time until you found him."
"Sans, wh-why are you s-stopping me? He still needs to… to be healed." Nyssa glances from Sans to Gaster.
"IT'S OKAY... SANS AND I HAVE A HISTORY TOGETHER. THIS IS... EPECTED." Nyssa shakes her head.
"I-it can't be a-anything that means I c-can't heal you." She attempts to look into Sans' eyes, but they're blank. "S… Sans?" He lets go of her wrist.
"fine. you're almost done anyways, so it's kinda pointless to stop you now. just, keep him away from papyrus." Sans turns and walks out of the room. Nyssa watches him leave, then she looks at Gaster.
"What… What happened between you t-two? Y-you're definitely not n-normal." She holds her hand out, and once again Gaster is covered by the light. As it disappears, Nyssa is finally able to completely see him. Gaster is tall, slender, and wearing black pants and overcoat with a white turtleneck underneath. The shirt has slim black lines running down it every couple of inches.
"AS I SAID, IT S A LONG STORY. FOR NOW... THANK YOU. I'VE BEEN TRAPPED IN THAT STATE FOR MANY YEARS. THERE ARE MANY THINGS I NEED TO DO, AND MANY FENCES THAT NEED MENDING."
"Well, if you kn-know what you need t-to do, th-then I should g-go home and rest." She smiles at him. "I-it was nice to m-meet you, Gaster." She waves as she walks out of the room, continuing her walk towards Snowdin. "Sans! I-if you're s-still around I-I could use a sh-short cut!" She shouts.
"yeah, i'm still here…" Sans hand waves from around a corner. Nyssa smiles sleepily.
"M-mind taking me home?" She hears him sigh as he walks from around the corner.
"sure. i think i'd rather be home right now anyways." With that the two disappear, and reappear in Sans' room. Nyssa yawns as she turns towards the door. However, she stops and looks at Sans.
"Hey… What d-do you have against that guy?" Sans looks her in the eye.
"gaster… there aren't a lot of pleasant things i could say about him. a lot happened in the past, but…" He half smiles. "you're too much like papyrus, you know that? you've got a big heart… no matter what i told you, you'd probably have healed him still." He shuts his eyes a moment, then he half opens them and looks at the floor, his smile gone. "maybe i'll tell you another time. i'm not really feeling up to it right now."
"Okay." Nyssa smiles at him, and he smiles back at her. "I'm g-gonna go to sleep now. H-he took a lot of energy." She walks towards the door. "I-I'm stealing Papyrus' bed for now. I d-don't think he'll mind."
"probably not. it's the middle of the day, so i doubt he'll even know."
"good night." She walks out, shutting the door behind her. Sans sighs as he sits on his bed and looks out the window.
"…night…"
