Episode Sans: Yet Darker
My original timeline... lies somewhat inaccessible to me. The last I could glimpse was a girl, but not just any girl. Chara Dreemurr was in a defensive battle against a ghost-posessed dummy. She saw me before then, but I assume she didn't recognize me...
In any case... I'm back here... in The Void. I hate calling this home, but I'm afraid its the only one I have now. Here, time means nothing to me. I can appear whenever, and wherever I want in the timeline at will, if only for several seconds.
But now I wish to move on. My... curiosity must be satisfied. I want to create a world that, rather than observe, I can manipulate. Yes... truly interesting.
The Void has given me unique, yet terrifying power. If I'm not careful in making this new timeline, I'll be back at square one.
Well... too late to turn back now...
Let's begin...
...
In the altered timeline, in 201X...
Sans was asleep in his room, unaware that somebody was watching... He was dreaming of a bright future... He saw another skeleton, bearing a similar physique to him.
But something was off...
The other skeleton... his smile suddenly disappeared, and his eyes turned a bloody crimson. Sans slowly walked backwards in horror as pitch-black hatred oozed from the stranger's sockets. Sans turned to run out the door behind him, but there was no door! The other skeleton appeared right behind him, grabbed him right shoulder, and muttered one line.
"I'm not the only one you'll wrong..."
GAHHH!
Sans woke up hyperventilating before he could hear the rest, his left eye glowing from stress.
"Sans!" His wife screamed, bewildered. "A-Are you o-okay?"
Sans took a minute to calm down, still thinking about what the other him said.
"W-What h-h-happened?" She asked again with a worried look. "Bad dream?"
"Yeah... I'm fine. Just a nightmare." He replied.
"Whew... what a relief. Just don't wake the children, alright?"
"Yeah... sure. G'night, Alphys."
"Nighty night."
Alphys fell back asleep that night. But Sans didn't sleep again until the next night. The thought that he'll betray someone in the future... The thought terrified him.

This chapter is important more to Alternate Experiment than to ExperimentTale, but I've uploaded this chapter onto both stories just in case. The Sans for Altered Experiment witnessed the dream in case you we wondering. This... is the true origin of Alternate Experiment. Also, yes, Gaster has the power of the Void, but he doesn't play a huge role in either story until later down the line.
