Once inside the house everyone began to talk about their next plans for today. Frisk turn when she notices Gaster began to walk away from the others a bit saddened. Frisk turn to see Steven too has noticed Gaster's strange reaction. So the two follow him outside. Once outside Frisk was the first to ask Gaster.

"Gaster, why do you seem so sad?"

Gaster smiles as he looks towards the beach, "you two I can't keep secrets from or hide my feelings from either. You both are to Determined to find out anything to help."

"Of course," said Steven, "we'll always willing to help."

"Yeah, always" added Frisk.

"Well then" started Gaster, "you see I can't stay here too long. I must go back in the void to stay all alone in there without anyone to even talk to."

"What?!" cried Steven, "nobody is to be left alone. Not at all! Besides, you have every right to be here with your sons and be around us. Your friends."

Gaster laughs, "that's awfully kind of you Steven but, sometimes life can't always have their happy ending. Can't they?"

Steven looks down remembering that Flowey is free but not eternity free of his real self.

"I guess I know what you mean."

Frisk look up at Gaster, "but you can't leave. You've just got here. I'm sure Papyrus would love to meet you. I don't think he ever saw you in a long time."

Gaster sighs, "or remembers me. He was too young when I vanish into the void. It's best he don't. Besides, I'll be alright. Knowing Sans and Papyrus are both safe. Seeing Sans began to fall in love with a gem. It makes me happy. I'm also glad to meet you two as well. I heard so much about you, Steven."

Steven smiles, "yeah, I just wish I could help you, Gaster."

Gaster looks at Steven, "maybe someday I'll be able to come back permanently and live with all of you. Yet I can always know you all stick together to keep one another safe. That's what makes me know you all don't need my help anymore."

"Please" plead Frisk, "please stay with us."

Gaster looks away from Frisk little puppy eyes. He remembers those exact look of Papyrus when he wanted him to stay.

"I'm sorry, " Gaster said in a whisper, "I can't stay I have to go. But promise me that none of you would ever forget about me."

Frisk and Steven both nods, "we won't ever forget you."

"Thank you" was Gaster's final words before he disappeared from them forever again.

"It's too bad we know where that void is."

Frisk nods, "yeah me too."

Amethyst came out and yell out, "yo there you two are! Hey, where's that weird dude?"

Steven look at Amethyst, "you mean Gaster?"

"Yeah, that guy."

Steven took a long sigh, "he said he had to go back to the void. Wherever that is. But he told us he might never see us again."

"Man," said Amethyst a bit surprise, "that's real rough."

Steven nods, "yeah, but he told us to never forget him either."

"Heh… he was a big help. But I guess things can't last forever. Right?"

"I guess so."

"Hey lightened up Steven, at least we are all back and well again. Nobody got killed."

Steven looks up at Amethyst and nods.

"Come on, let's get back home," said Frisk.

All three ran back inside to meet the others at the warp pad. Sans notice his father wasn't with them.

"Shay where's dad?"

Frisk explain why Gaster left. Sans looks down sadly with Pearl petting his back.

"Sometimes we can't have what we want. I know how much you want you dad back."

Sans nods, "yeah, it's just why? Why did he leave again?"

Garnet looks at Sans, "perhaps he had other things to do. He knows you two are needed here. Especially with Pearl."

Sans looks up at Pearl. He knew Garnet was right. He had his brother, Pearl he holds so dear to his heart, Frisk, and everyone else he cares about. They all needed him and if something happens to him they would all miss him.

"Thanks, Garnet," said Sans not looking away from Pearl, "needed that."

"Anytime" smiled Garnet.

Once Amethyst, Steven, and Frisk all got on the warp pad. They all got right back to Mt. Ebott. Undyne walks off as the dogs went heading towards home. Sans stop Undyne as Undyne turn to Sans with curious.

"What's up Sans?"

"Thanks," he says "for uh… saving me and the kiddos."

Undyne smiles, "ah… anytime Sans. Besides I did promise your brother that I'll keep you safe."

Sans look at Undyne, "how badly is he?"

Undyne sighs, "I guess that punk told ya, huh?"

"Yup, so how is he?"

Undyne gulp as she try to find the rights words to explain this to Sans.

Just then Frisk happen to notice three monsters coming up on the path of the mountain. She looks closer to see Alphys, Toriel, and Papyrus all walking up towards them. Frisk smiled wide as she ran towards them.

"Mom, Alphys, Papyrus, thank goodness."

Toriel smiles as she ran to hug her child once more, "oh Frisk I'm so glad you are safe!"

Everyone turn to see the three hugging Frisk (though Papyrus could only hug Frisk with one arm). Sans ran towards Papyrus with blue tears streaming down his face.

"Papyrus!"

"Sans, you're alright!"

Papyrus ran to Sans and the two of them hugged each other. Sans notice the brace on Papyrus arm.

"That kid really got a hold of you."

"It's okay brother, I'll be fine. I'm just glad that you and everyone else are all safe. Especially the human Frisk. I was so worry that Chara would… would…"

"Hey, hey, it's okay bro, I'm fine. Everyone is a okay. Alright?"

Papyrus nods as he wipe his orange tears from his eyes.

"Don't worry that kid won't be messing around with us anymore. We all made sure of that. Especially the two kiddos."

Amethyst nods, "yeah, you should seen what those two look like when they are fused."

"Fused?!" cried Toriel.

"Yeah," said Steven with a wide smile, "me and Frisk were amazing! You should have seen how we fought Chara. We even call ourselves Stevisk!"

Toriel looks down at Frisk who is nodding her head at her mother. Alphys looks at Undyne nervously.

"I… Is that… true?"

Undyne nods, "yup better believe it, Al."

"Oh… m… my."

"Wowie" cried Papyrus with enthusiastic, "that's so cool!"

"I know," said Steven, "we were so amazing!"

Flowey sighs as Garnet handed Flowey over to Alphys, "yeah, something I won't forget. Why did I even mention about fusion? Me and my big mouth."

It was time for Frisk and her family to head home. So Steven and the three gems got back up on the warp pad and vanish after saying their goodbye to everyone. Once back home Amethyst and Steven went to play video games while Garnet and Pearl went into their rooms.
