Frisk felt very pleased with herself and all the good she had done. Most of the monsters she had met were now kind-hearted, nice people. They weren't perfect but they were certainly trying and that's all she could ask for. 

She had stayed with the monsters for almost a week now as Alphys tried to make her a way home. All of the monsters had been taking good care of her but now they were out for a final walk through Waterfall, Frisks favorite place for a scenic walk, before she went home. They stopped by the echo flowers that were repeating compliments and stories that other monsters had said as they passed by. 

"I've never heard the echo's say such nice things." Sans said and the echo flower beside him repeated his words a few times. 

"I haven't either. It's odd to hear such good things after so many years of hatred." Papyrus replied. Once again, the echo flower repeated the words it heard.

"I'm glad I could help." Frisk decided to lie down on the ground with her arms behind her head listening to the echos of herself and monsters. 

The brothers joined her on the cave floor in similar positions, their eyes fixed on the rock formations above them that were glimmering like stars, reflecting the beautiful blue glow from the water below. It was peaceful.

"So what now kid?" Sans asked. 

"I have to go home. They're probably worried about me." She replied. 

"I know. Well kid, we'll miss ya and we'll never forget what you did for us. None of us will." Sans smiled. 

"Come on guys. Lets finish our walk." She sat up and pulled them close, "I love you guys."

They hugged her back tightly and then continued on their walk towards Hotlands. They soon came up to the large white lab near the entrance to Hotlands and walked inside. Alphys was working on a machine similar to the one that Frisk had seen in her Alphys's lab. 

"Well Frisk, based on what you told me, this is what I think brought you here. I started working on this a while ago but I got bored. We never wanted to reset." she trailed off, thinking about something. 

"Thank you Alphys." Frisk hugged her. "I guess it's time to go home. Goodbye guys. I love you so much." They all embraced and Frisk noticed the tears in their eyes. "Don't cry guys. It'll be ok."

"It will be, thanks to you." Sans said.

"Alright. I-If you're r-ready to go home, s-step over there and I-I-I'll send you home."

Frisk nodded and stepped over to where Alphys told her to go. Sans and Papyrus looked at each other and back at her then stepped forwards. 

"Kid we got something for you before you go. "

They handed her a potted echo flower. The pot itself was decorated with pictures of the brothers as well as Undyne and Alphys that were obviously drawn by them. Underneath the pictures were their signatures. The flower inside of the pot was wilting a little bit. It wasn't repeating any of their words either. 

"I love it guys! But I think it's dying..."

"No. It'll get better as long as you water it. When you uproot an Echo, it'll wilt for a while but when it blooms again, it'll repeat the last thing it heard before it was uprooted, forever."

Frisk had tears in her eyes now, "what will it say when it's better?"

"Ah ah ah! It's a surprise. NEH HEH HEH!" Papyrus laughed.

"I can't wai-" 

Frisk was interrupted by Undyne running in. 

"Human wait! You can't leave without saying goodbye to me!" 

Undyne lifted her off the ground and hugged her tightly. When she was put back down, she gasped for breath. Undyne's grip was way to tight for a comfortable hug but she still loved it. 

"Of course Undyne. Bye-bye everyone. I'll miss you all."

They all waved goodbye and before Frisk knew it, she was back in her own universe. She was in Alphys's lab which was completely dark and quiet. The only light available was the faint glow of the echo flower in her hands. 

Suddenly, a beeping noise could be heard outside the lab as well as yelling from multiple people. The door was kicked in by someone wearing a pink knee high boot that she instantly recognized as Mettaton's metal leg. 

"Frisk! Darling are you in here?!" He turned on the light.

Mettaton, Alphys, Undyne, Sans, Papyrus, Toriel and Asgore ran into the lab. Mettatons chest was beeping and a red light was flashing from what she could only assume was a tracking device that Alphys had installed to find her.

"FRISK!" they all yelled in unison. 

They were all screaming different things, asking if she was OK or where she went. As everyone panicked, Frisk stayed relatively quiet. Her smile never faltered. 

"I'm fine. I met some new friends! I'll explain later." 

A few hours and a lengthy explanation later, the group were sitting, teary eyed in the interview room of a police station. The officer in charge of the missing person case they had filed when she first disappeared, was stunned by the things that the young child was saying and what she had done. After so long with the monster, knowing what they were capable of, he didn't doubt her story. 

"You've got an amazing kid here. You guys take good care of her."

"Do you think we aren't, Darling?" Mettaton questioned. 

"Never. Well I think you guys should go. I'll file this paperwork. You can go home."

They thanked him and went home. Frisk yawned, signalling that she was tired. The monsters said their goodbyes, hugging before they went, and finally separated. Sans, Papyrus and Toriel brought Frisk home. She was tucked into bed by Papyrus and Toriel and kissed goodnight. Sans walked into the room as they were on their way out. 

"Don't be long Sans. She's tired." Toriel said. 

"Don't worry Tori. I'm just saying goodnight. No Fluffy Bunny story tonight." Sans chuckled.

She smiled down at him and proceeded down the hallway. Sans walked into the bedroom where Frisk was warmly tucked under the blankets.

"Hey kiddo. Ready for bed?" He said as he sat down on the bed by her feet. 

"Yep! I missed you Sans. But other you was cool too." She giggled. 

He was smiling as usual but she could tell that he was happier than he normally was. Happy for her safety and happy for her return. 

"Kid, I'm proud of you. You never give up and I'm proud of all you've done." 

"Thanks Sans. I'm just trying to make the world, well, all worlds a better place."

"I know," he pressed his teeth to her forehead in an effort to give her a goodnight kiss. He walked back over to her door and stopped. He knocked on the door. "Knock, knock."

She giggled, "who's there?"

"Olive"

"Olive who?"

"Olive you, kiddo."

And with that terrible pun, he turned off the light and was gone. She was left, surrounded by a complete, familiar area shrouded in darkness. She was happy to be back. The glowing Echo Flower was over on the window sill across her room. It was slowly gaining its rich blue colour back. Suddenly it broke the silence, muttering a quiet but distinguishable, "we love you!" that she instantly recognized as her friends from the other universe. The reassuring voices of her knew friends, despite the distance between her and them, helped rock her to sleep.
