Chapter Seven

The Mix-up

A month had flown by since Undyne and Alphys had been the last to come to the island. Mettaton and Papyrus lived in the ‘spare’ room in Melinda’s house, with talk of them building a house on the island as well, but no one was really in a hurry to get that done.

Melinda realized they needed some more things in the house and decided to go to the mainland to shop. She went alone this time, just to get some time away. She loved the island and the little community it had become, but things sometimes were a little crazy. It was nice for her to just get away from time to time, even if it was to do the dreaded grocery shopping.

She had been at the store for an hour and was almost done when she got a call. It was Sans. She giggled a little and answered.

“Sansy, you act like I’ve been gone fo—“

Loud static.

“Sans?” Melinda was panicked now.


“S-sansy??” Melinda frantically yelled into her cell, causing people to stop and stare. She completely abandoned her cart and ran out the door. She still had the phone in her hand as she ran down the street, making her way to the beach. She could hear strange voices from time to time. Other times, there was nothing. Occasionally she would call Sans’ name again, just to see if he was there. It was like he dialed her number, then dropped the phone. She was terrified.

She got to the boat, the phone up to her ear, but before she could start the engine on the boat she heard someone say, “Don’t come yet…”


Melinda stared at her phone, dumbfounded. “Don’t come yet?” It was like a warning. She wondered if she was in danger, or if she misheard something. The voice who said it was none of the voices she had come to know. He sounded like Sans, but not at the same time? His voice had a bit more of a formal tone, and just sounded…different. She couldn’t figure out how it was different. It just was. She started the boat and headed off to the island, going as fast as she could.

Once there, she couldn’t jump out of the boat fast enough. When she did, she looked around. Everything was normal. Nothing was out of place, no weird sounds, no nothing. She started to get angry, thinking it was a prank. She marched up to her house and through the door. Papyrus met her in the living room. His face was white as a ghost.

“Papyrus! Are you alright?” She asked.

Papyrus shook his head. “No. Something is wrong with Sans. He’s gone. There’s someone else here now too, claiming to be Sans, but he doesn’t look like him.”

Melinda was confused. Was that the voice she heard? “Where is he?”

Papyrus pointed to Melinda’s room. Then he slinked down onto the futon.

Melinda looked at her room. The door was shut. She slowly opened it, heart pounding. She looked at the bed and saw someone lying on it, Sans’ phone next to him. Her eyes widened. Gaster. The Mystery Man from Undertale. This man had the same lines on his face, but somehow, he still looked like Sans. His clothing was different now too. Black jeans, Black boots, a gray turtle-neck and a black jacket with gray faux fur lining. He appeared to be taller, too. No wonder Papyrus didn’t recognize him! But what happened?

She got up onto the bed. She saw the phone laying there and picked it up. The last number dialed was hers. This was Sans. Or at least, someone who looked like him, and had his phone. She climbed above him and hovered. Then she smiled. He was handsome, whoever he was. She decided to see if it really was Sans or not. She leaned down and kissed him.

His eyes opened slowly. He pulled her down onto him and kissed her back, aggressively.

Melinda broke the kiss. “Hey, hey, wait.” She sat back up on the bed.

The man looked down. “I didn’t think you would come. I told you not to. Everything was….it’s all….blurry. Faded. And now my own brother doesn’t even recognize me.” He looked up at her. Her face was pale and she looked shocked. “And….neither do you.” He sighed.

“Sans?” Melinda asked. But was it Sans? His eyes weren’t that cyan color anymore. They were golden. And those scars! She leaned toward him and touched his face. “What happened?”

He looked down again. “I-I’m not sure. I saw…someone….familiar. He said his name was….ehhh…”

Melinda lifted his head up. “Gaster?”

“No, no, not him. But close.” His golden eyes focused on her. “G. The name’s G. That’s what he said to me. But he looked like me, only with scars.”

Melinda’s eyes went wide as she thought of all of the AU’s he could have been from. “Oh my God,” she said. “Gaster Sans. AKA, G. That’s who you are.”

“Who I am?” He was shocked. “I just saw him come in. I look different?”

“Think back, Sans.”

G closed his eyes. He remembered someone coming in and asking him for help. He agreed to help the person, but he remembered being worried that Melinda might be mad at him. He remembered his hesitation, and then his final agreement.

“He needed help. He was like Lust, a spirit of a Sans AU, but he had a physical body. Not for long though. He asked if I would help him. He needed a physical form. I didn’t want him to die off, and he said I would still be in his conscious mind like Lust is. His name is Gaster Sans, but he prefers to be called G, and that’s who I am.” G looked at Melinda. “Are you upset?”

Melinda smiled and pushed him down on the bed. “Upset? No! You had me scared to death, though. But I don’t care what’s on the outside. I fell in love with you, and as long as you are still here, I don’t care what you look like. Although…you have a very…sexy appearance.” She giggled.

G smiled. “Heh. Well, I can be quite a bit more aggressive than the Sans you know. Don’t get me wrong, I will still go easy on you if you want me to.” He leaned in and kissed her neck. “But I can’t make any promises that it will be all the time,” he breathed in her ear.

Melinda shivered. “Ugh Sans…I left the grocery store freaking out, thinking you were in serious danger, and once you fully come to, you start teasing me?”

G laughed a little. “Of course.”

Melinda playfully patted him. “Sans!” She laughed, then teased him right back. She kissed his neck, nipping at it a little. “We can save the good stuff for later,” she whispered.

G grinned. “Promise?”

“Yes,” Melinda smiled. G could see she had something planned for him already.

“I can’t wait.” He narrowed his eyes and pulled her close to him. He kissed her. She kissed him back, but broke the kiss and put her finger up to his mouth. He licked it teasingly.

“Stop it,” Melinda said seriously, but breathlessly. “You really need to go talk to your brother. He is petrified.”

G stopped in his tracks. “Oh God, Pap….he saw me like this, but didn’t realize it was me!”

“Yeah,” Melinda agreed. “Let’s bring him and Mettaton in. If we tell them together, it might be a little easier.” She started to stand up, but G pulled her back down.

“Uhh, not yet.” He cleared his throat and looked down. Melinda followed his gaze and laughed.

“Oh but right now would be perfect!” She joked. G didn’t realize she was joking, because she still started heading for the door. He pulled the blanket up over himself. Melinda laughed. “I’m joking! I would never do that to you.”

“Oh. Right. Heh.” He pulled the blanket down.

Melinda sat beside him. “You seem like you’ll be a lot of fun. And that’s saying something. I’ve been with Lust more than once.”

G grinned again. “Oh Lust has got nothin’ on me, dollface.”

Melinda laughed. “Well, I guess we will find out later. Or, maybe sooner than ‘later’ if you will allow your brother in the room.”

G sighed and looked down. “We’re good now.”

Melinda giggled and opened the door. She went out to find Papyrus and Mettaton. They were sitting outside the house, watching the sunset.

“You know, you’d get a better view from the beach,” Melinda winked. Papyrus and Mettaton both jumped, not expecting her to be there. Before they could say anything, Melinda spoke up again. “Could you two come with me please? I found Sans, Papyrus.”

Papyrus was perplexed. “But you didn’t leave that room.”

“Exactly. Just come with me. You’ll understand.” Melinda walked back into the house, and back into her room.

Papyrus and Mettaton followed her in, and they all sat on the bed. Melinda cuddled up with G, and they both explained the story to Papyrus and Mettaton.

“Ah, yeah, I remember something sort of similar, or at least a story Alphys had told me I think.” Mettaton said.

Papyrus looked at him, then back at G. “So you’re Sans? You’re my brother?”

“Yes,” G responded. “I am still him. I just look a bit different. And well…I’m a little more confrontational, edgy and aggressive. But I won’t do that to people I love. If anything, you just gained a better protector.”

As he spoke, Melinda started to feel strange. Her eye felt…different. It was her left eye, and it seemed to be going in and out of focus. Papyrus noticed Melinda blinking harder than normal, over and over, then Mettaton noticed. Her eye was starting to flash. Cyan and yellow, like Classic Sans. She kept blinking it away, but it started back up. Eventually, it became so painful, she started to wince and hold her eye.

G immediately stopped and looked at her, as her had covered her eye. “What’s wrong?” He asked.

“My eye…it feels like someone is stabbing it!” Melinda shouted.

Papyrus and Mettaton decided they should go.

“We will leave you two alone to figure this out.” Mettaton said. He left.

Papyrus smiled. “Brother, I’m so glad you are still here with us. If you need anything, please let me know!” He left as well.

G turned off the light in the room, and Melinda’s eye-flashing slowed. “Wh-what was that?” She asked.

G was hesitant, even though he knew what it was. “Looks to me like we have more of an issue than just me coming here. Magic went screwy, and it looks like you might have Classic’s magic now.” He looked down at her, and her eye had completely stopped flashing. “Which means, if magic went crazy, and brought me here, who else did it bring?”

Melinda looked up at him. “Oh no. Should we be worried?”

G shrugged, “I have no idea.” He cuddled her. “But we should keep a lookout for new people the next few days.”

Melinda nodded in agreement. “Yeah.”

They fell asleep, cuddled close. But Melinda awoke in the middle of the night. It wasn’t due to a nightmare, though, she just….woke up. She rolled over to get comfortable again, and noticed that G had started to stir. He rolled over as well and cuddled her. She smiled and sighed gently in approval.

G smiled. “So you’re awake.”

Melinda opened her eyes again. “Yes. I guess it’s all these weird things that are happening.”

G sighed. “It’ll take some getting used to. I’m just glad you accepted me as G.” He was gently running his fingers down her sides, trying to calm her. He was actually doing the opposite.

Melinda shivered a little. “Y-yeah. Why wouldn’t I?” She tried to act like it wasn’t turning her on. Apparently, during the switch, G had forgotten what got her going. Not that he had to try too hard. There was something about him that attracted her even more than he had before. Something different about this Sans that attracted her even more than Lust did. She rolled over and kissed him before he could answer her.


“Ugh, that was amazing, G.” Melinda smiled up at him.

“Same to you….LUST.” G grinned.

“H-huh?” Melinda was confused.

“I saw your eyes flash purple for a moment. Looks like it’s not just Classic’s magic you got in the mix-up. We can add Lust to that list now.” G winked.

“Oh, that was just for a moment,” Melinda replied. “I felt it. I can try to make sure that doesn’t happen again, if you didn’t like it.”

G kissed her. “No. I like the mixture. I’m excited to see what happens when you are angry.” He smiled. “That will be pretty damn sexy.”

Melinda shivered. “Ughhh…don’t do that, G.” She stopped for a moment. “Uh, by the way, do I call you Sans or G now?”

“Whichever you want, dollface.” G got off of her. “I’ll respond to both.”

Melinda rolled toward him and cuddled. She rested her head on his chest and listened to his rapid heartbeat. She listened as it started to slow. She grinned. “I really did a number on you, eh?”

G laughed. “Well, I suppose so, but I also did a number on you.”

Melinda grinned, and they closed their eyes and fell asleep in each other’s arms.
