Reaper Sans:

You were leaning against your pink scythe as you watched the Christmas party from a distance. 'Too much drama.' You thought silently to yourself. You then noticed a version of your oldest brother walking towards you. "Hey, are you a...?" "Reaper? Well. Kinda. I don't travel around AUs like you do. You could say I'm an the executioner of brats."

You started to have a nice chat with the guy. "Don't you hate it when souls just WON'T die?!" Reaper asked, you nodded and told him about when Chara would NOT DIE. Reaper then told you about his AU and how you'd make a great goddess of death. "Well, remember, I'm just from a different timeline of Undertale. You have a sister in another timeline." Reaper nodded and smiled before you both chatted and tried each others scythes.

Geno and Afterswap Papyrus: (aftertale you)

You all looked at each other and looked at what you were wearing. "We understand each other." You all said at the same time. You all then sat down and talked about your siblings before the Genocide run.

Sciencetale:

"It's illogical!" "Let it goooo alreadyyyy!" Sci was complaining how your magic should have ripped your body apart and shattered your soul into dust. "HOW IS THIS EVEN POSSIBLE?!" You groaned as you read a comic you found. "Does it matter?!" You asked as Sci ran the machine one more time to make it a million. "YES!" Sci exclaimed as he read the results.

"You have issues kid."

"WE'RE THE SAME AGE!"

"Well then, you have issues Sci."
