Sans and Olive had stayed up very late for the past few nights looking at other timelines, Olive mostly was building numerous machines that could open the timelines, only some worked. The machines that worked either worked for about 5 seconds, or it worked for any period of time she wanted, but it was extremely dangerous. Until one night... Olive had built a huge machine and it was made form the last bit of parts she had. She turned it on!! But, no luck. Olive put her head down on disappointment.
"Olive, I'm so sorry.." Sans said, putting his arm around her.
"It's not your fault.. it's mine.." Right as Olive said that the machine started to open up a Timeline! Olives head was still down to Sans had to point it out to her.
"Olive!! It's.. It's working!!!"
"Oh my god!!! YESSS!!!!" She said, hugging Sans.
They walked inside the first available timeline called 'SWAP' which they assumed was the opposite of themselves.
They stepped in and the portal shut behind them.
The first thing they saw was Sans and Papyrus with swapped personalities, Mel and Olive with swapped personalities, and Frisk and Chara with swapped personalities.
"Your hair is long and you are dressed kinda girly!" Sans whispered.
"Shut up! You literally make James Charles look straight!!" Olive whispered back.
"I honestly don't think I'm a boy in this place."
Olive cleared her throat.
"Uh, excuse me, can I talk to you really quickly?" Olive asked politely.
The other Sans dropped the other Olive face first on the ground and skipped over to us.
"Who the- are you me?! Is that Livvie?!" Said the other Sans with a high pitched voice.
"It's hard to explain. We are Olive and Sans but from another timeline." Said Sans.
"Uhm, You can call me Livvie." Said a bitchy voice.
Sans held back tears of laughter and Olive elbowed him.
"Ok, y-you can call me Olive."
The other Sans walked up to Sans and squished his cheek.
"You can call me Blueberry!" Said the other Sans that was now Blueberry.
"Uhh... call me Pap or something." Said the other Papyrus with his cigarette in between his boney fingers.
"Heh, call me Queen Sarcasm." Said the other Chara.
"This is weird..!" Said Blueberry.
"Well, what exactly did you want to talk about?" Asked Pap.
"Yeah, we wanted to know if you have any intention of hurting us?" Asked Olive.
Everyone except Olive and Sans looked at each other with "Nah." Echoing across the scene.
"Oh, and one more thing." Said Sans.
"What's up?" Asked Queen Sarcasm.
"Do you know about any other timelines?"
The other Mel stepped forward.
"FELL." She said.
"Ok, thanks. Would any of you have any interest in meeting the others?" Asked Olive.
"Why not?" The other Frisk said.
"Alright, follow us." Said Olive as She pulled out the remote that controlled the portals and clicked a button. A portal popped out of nowhere and in they went.

TIME SKIP

"Bye!" Said everyone to each other as the people of the swapped timeline made their way to the portal, and back to their world they were.
"That was really cool! Now what's next?" Frisk said.
"So, they know about a place called 'FELL' and apparently it is us but more edgy, dirty, violent, mean, and harsh." Stated Olive.
"Yeah, not looking forward to me being edgy. Let's hope I don't look like an emo 14 year old from 2002." Sans said jokingly. Everyone laughed at Sans's joke.
"Well, I guess that's our next plan. Objective FELL." Olive said, DETERMINATION shining in her glasses.
