Undercreep: Sanses Cross Eye

In year 201X Sans went to his dads laboratory because he wanted to tell his dad about Papyrus's first day at school. But when Sans went there his dad was acting wierd. "Uh... Hey dad papy just came back from his first day of school... Are you ok?..." Sans asked and Gaster awsnerd "Come here sans... I need to ask you something.... Its a favor.." Sans was alittle scared and stepped closer to his father. "what fav-" befor sans could finish that sentence his father knocked him out. A few hours later Sans woke up with pain on his right eye. He could only see with one eye. He was scared and called out " Dad?! Dad what did you do??!" Gaster only said this "don't worry sans... Your fine.." Suddenly Papyrus came into the labor and saw that Sanses right eye was a cross now. "Bwother Your Ewe!!!" He called out. "What? What's up with it papy?" Sans asked scared. "Itws a Crwoss!" His little brother shouted. Sans ran to the bathroom and looked at his face and saw that his right eye has become a cross. "DAD WHAT DID YOU DO TO ME?!" he yelled at his father. Gaster laughed "oh Sans look it was an experiment but I failed.... I'm sorry  but you won't be able to see with both eyes every again..." Sanses eye started to glowing and he wanted to attack his father but he only teleported back home in his room and started to cry. For now on he really hates his father and wishes he was dead.
