Chapter One: Three Months Later
Frisk's eyes flutter open, struck by the sun. As she lay in her bed, she smelled the warm scent of butterscotch in the air. "Breakfast. Much better than Sans' ketchup omlettes..." she thought. She got up and went to the kitchen. Two flights of stairs later she was sitting at the table, eating butterscotch pancakes. Toriel was at the sink, washing the dishes. "So, my child, Sans has been teaching me some of his jokes. I have become quite skilled with these 'puns'. Would you like to hear one?" Frisk sighed internally at Sans. "Sure!" Toriel cleared her throat. "Before I start, did you like the pancakes?! If you want, I could give you a 'tu-Toriel'!" She broke into laughter. "See, child? I have learned a lot! Hee hee!" Frisk grinned. It was at least a little funny. "Good one, mom." she said. She finished her breakfast and put her plate away.
She went to go find Sans and Papyrus. If she could, anyways. The house was huge. When they had come to the surface, they couldn't find a good place for all of them to stay near each other, and they wanted to stay together anyway, so they just bought a massive home in the foothills of Mt. Ebbot. It cost several million dollars, but that wasn't much of a problem. It turns out magical gold has a really high exchange rate. So now Frisk, Toriel, Asgore, the Skelebros, Undyne, and Alphys all lived together, and Mettaton visited from time to time. With three floors, space wasn't a problem.
She finally found Sans and Papyrus in a sitting room, playing video games. They had bought a Wii U on Sans' recommendation, and now that was one of the brothers' hobbies. Sans could beastmode some Smash Bros., always destroying Papyrus, mainly because he was too busy giggling at all of the flashing lights on the screen. Sans would take this opportunity to end him with a Final Smash every time, and anytime an ultimate move was used, Papyrus threw the pad down, hopped up and down, and fangirled vigorously. That was often a sight to see, as being a nearly 7 foot skeleton, he rattled noisily and had one time accidentally put his head through the ceiling. Until Sans pulled him out, he just hung there and casually conversed with the house spiders.
It had taken a while for Sans to completely trust her, because having knowledge of timelines, and having your brother killed in said timelines, were not good together. Eventually they fixed that problem. Now, Frisk was Sans' best friend, aside from Papyrus. He was also a pretty good magic tutor. He taught her the basics of blue magic, like how to control the effects of gravity. She was doing well, with the best she could do being pressing Sans into the ground. He wasn't resisting, and his practice sessions took the whole day to complete, which helped with time and effort. He took advantage of the opportunity. "wow kiddo, you're really pressing yourself to your limits this time, huh?" Seconds later, breaking glass and a rattling thud came from the direction of the house.
After practice, shortly before sundown, Frisk and Sans retired and went back for dinner. While she was eating, several glowing blue spears smashed through a wall and embedded themselves in a china cabinet. Toriel seemed to materialize from upstairs, screaming at Undyne, who was worriedly looking for a hiding place, and a way to conceal the TV she tried to spear. Frisk decided she didn't want to see how badly that was going to turn out. She went up to her room and got ready for bed. As she turned the lights off and cocooned herself with quilts, she didn't notice the puppet, laying on her dresser, held up by blue strings that just ended in midair. When she finally fell asleep, the puppet was shadowed in an inky darkness, and was gone in seconds.
