Edit: These first two chapters I'm not very proud of, and I was a bit over-excited while writing them, and just kind of wanted to make all of the things happen as quickly as possible. However, I think instead of re-writing them, as this is my first piece of writing, I think I'll use it as a then and now segment for later. Chapter three is when my writing and ability to control myself start to form, so if you're willing to bear with me, I hope you will find the later content to be much more enjoyable.

The letter had been there for almost a week. Sans had not opened it, for fear of what it held. Knowing that he had time travelling capabilities, it was obvious who the person who handed it to him was, however, he was afraid that the perfection of the new world would be ruined if he read this letter. "I've been stuck in an infinite loop of apathy for such a long time… I don't want to go back… I don't want to read whatever this letter contains… I just want things to be the same…" Now that humanity and monsters were finally coexisting peacefully, and it seemed like everything was going to be perfect, someone hiding in a hoodie had come up to Sans, and given him this. The most horrible thing about all of this, is that he had that exact same envelope sitting on his window seal, so it was much more than a possibility that it was from himself. Sans's eyes darted around the room, making sure that nobody else would be there to sneak a peek. "Oh for the love of god… fine, I'll bite…" He opened the envelope, straight away he was able to recognize his own handwriting.

Dear Sans,

I know that you will not want to hear this, but there really is no other option at this point. I know that you feel the best you ever have right now, but there is a major flaw with your timeline that you need to try to fix. Your friend Frisk, well… he's gone on a timeline rampage I'm afraid. He constantly resets timelines, and he goes on murderous rampages, killing everybody, even you and Papyrus. You may think, "There's absolutely no way frisk would do such a thing." You'd be right to assume that, but when he resets, something takes Frisk's body. A being lost in time and space. I'm not sure how, or what means were used to do so, but I do know what caused Frisk to reset in the first place. He wanted more power, but not in the way that one would typically expect. He didn't want to become all powerful, and destroy everything, he just wanted enough power to save the one person in your timeline that he couldn't save. You can't tell, but behind the façade of "Oh, look at me, I'm the happy charismatic monster ambassador," he's actually losing his mind to it. There was someone he didn't have the strength to save, and despite his best efforts, he could only temporarily regain him. You must approach him about this, and figure out a way to fix that problem, lest he become taken over in his lust to save absolutely everybody.

Yours truly,

A fellow time enthusiast

Sans was silent for the longest time, and with good reason. The letter had been as vague as possible, and asked something he didn't even know happened. "I thought that the kid saved everybody… who was left other than…" Sans stopped talking aloud, as he heard footsteps outside his door.

"Sans! Aren't you coming down for dinner? I, The Great Papyrus would be very disappointed if you didn't come have some spaghetti," Papyrus sighed "and yes… I bought you some ketchup from Grillby's, because I felt like you were having a bad time lately." Papyrus said, compassion in his voice.

"Nah, I'm good bro… I'm not really hungry… besides, aren't you always telling me that skeletons shouldn't drink things because they go right through them?" Sans said meekly. Hearing this, Papyrus stood right outside Sans's room.

"Okay, what's the matter? You and I both know that the last time you turned down ketchup because I told you it was unhealthy was… well, not applicable, because it never happened, and I'm not even going to remark on that 'passing through me' thing!" Papyrus exclaimed.

"Well, being a skeleton, I'm not sure if I can… STOMACH eating right now." Sans said, partially trying to lighten his own mood. Papyrus stared at Sans's door distastefully

"On second thought, you can microwave it when you feel up to eating…" papyrus said while he walked away to his room. Sans had decided that he had to do the right thing, and go and talk to Frisk.

"Bro, I'm going to go out to eat actually, I've been dying to try that Mettaton face steak, so it's going to be quite a walk, don't wait up for me." Sans yelled, expecting a response, but there was no reply. Sans strode through Snowdin, gathering his calm and cool, before teleporting over to the ruins. Sans looked around when he arrived, and noticed that pathetic looking flower over in the corner. The flower seemed to be muttering something, but Sans ignored it, and went to Toriel's house. Sans knocked on the door, and Frisk answered.

"Hey Sa-" Frisk was cut off by sans

"Kid, I need you to spill the beans about what happened on the day that you shattered the barrier." Sans looked desperate, staring into frisks eyes.

"…I told you before… I really don't like to remember that day…" Frisk stared down at his hands.

"Frisk… I need to know… you never know, I might be able to help you with some things, if you'd just give me a chance." Sans was starting to lose hope at this point, he'd tried countless time before to get him to spill the beans, why would this time be any different?

"Sans… I'm not even the one who needs help…" Frisk started to cry silently.

"Then tell me who does frisk… I hate to see you hold all of this in… you're not alo-" Sans was cut off by Frisk's scream.

"It was Asriel! Asriel Dreemurr! Asgore and Toriel's son!"
