Undertale: Gaster, the Insane SkeleDad

Looking at the first bit Sans would look insane

"I'm gonna head inside." Toriel stood up "I'm going to the library, if there is any trouble call me immediately."No problem Tori." Sans waited for Toriel to be out of sight "Alright, Gaster lets talk..."
'Sans you know why your eye hurts... Don't you?' Sans smiled, it was forced "I'm not bringing you back, I've tried, I've succeeded, you've killed... I can deal with it..." Sans sighed "Why are you in my head... How are you in my head..." Sans couldn't help but feel a smirk coming from the man who's face wasn't there. 'Exactly... I've killed, I won't do it again... I give you my word, as a friend. Besides it just proves that I can change the timelines in a big way.' Sans let out a laugh "Well Ga-" He heard a scream "I'll catch up with up on that." Sans ran inside the house with a bright flame in his eye, another scream. He turned to see Frisk sitting completely emotionless as Papyrus shivered in fear. "Ok which one of you turned on a horror movie."

Sans sighed, it was half out of relief that Frisk wasn't about to start murdering everybody and half pissed off because Frisk turned on a horror movie and if Tori found out he would surely die... Well there would be a lot of yelling anyway. "You sure your gonna be able to sleep bro?" Papyrus laughed slightly "WELL IF I THE GREAT PAPYRUS CAN NOT SLEEP! I will be sure to ask you for tips!" Papyrus was feeling better but would probably need more than his night light to get a good sleep tonight.

Toriel looked around. The super market wasn't as super as she had first imagined it. She remembered when Chara told her about it... They would draw pictures make it look like a test of strength and speed to acquire food and such, but she supposed that Chara had an excellent sense of humour... Dark at times but they always tried "Well that was along time ago... I won't be seeing them for a long time..." Toriel put an apple into her basket "Oh hi Tori..." A voice said from behind "Toriel I mean!"
