Lightning Song and Sans: The Story of the Past

Meeting Undyne and Alphys

~~~❤~~~

Alphys was next on the list.

Sans knew today was the day where Alphys stayed in all day and watched anime. He hoped he wouldn't be much of a bother by interrupting her binge-watching, but he figured she would take a great interest in Lightning Song. Sans had only planned to tell Papyrus about the pony being from another dimension, but Sans trusted Alphys. Besides, Alphys loved to see a "peculiar specimen" every once in a while.

He wanted Lightning Song's presence to be a surprise. So, he had told her to hide in the hood of his hoodie until he introduced her.

Sans knocked on the door, feeling behind him to make sure Lightning Song was still there. She nuzzled his hand with her muzzle as if she was giving reassurance. He waited patiently until the door finally opened to reveal a yellow lizard still in her nightclothes.

Alphys gave Sans a strange look, which was also followed by agitated eyes. Sans knew today was the day she should not be bothered. Not even by her girlfriend. It better have been important for him to drag her out from watching anime. "Wh-what do you need, Sans? I'm r-rather busy..."

Sans flashed a smile, acting as if he hadn't disturbed Alphys's one day of the year where she spent it all to herself. "Sorry to interrupt ya, Alphys. But I think I have something- or someone- that will make this worth your while."

Alphys raised a brow and adjusted her glasses, giving Sans a "go ahead" look.

Suddenly, the skeleton pulled out a small pony with wings from the back of his hood. She was smiling, her wings fluttering. Sans held Lightning Song close to his chest, ruffling up her mane. He looked up at Alphys, finding that she wasn't exactly impressed.

"You came a-all this way just to show me a m-monster?" Alphys was close to just shutting the door on him completely.

"No, you don't understand." Sans set Lightning Song down, watching as she nervously glanced at the floor. "This isn't a monster, Alphys. This is Lightning Song..." Sans slightly hesitated before he kept going. "And she's... from another dimension."

Alphys had just about laughed. She knew about Sans's abilities, and she knew he could teleport anywhere at any time. But he knew that teleporting to other dimensions was dangerous, and so he had never attempted it. But now he was claiming this small pony was from another dimension he had to teleport to? "Sans, jokes like t-that aren't funny," she stated, giving Sans a serious look.

"This isn't a joke," Sans said in the sternest voice he could muster. Did everyone think he was joking when he told them Lightning Song was from another dimension? "This is real, Alphys. She's from a dimension called Equestria. And I know this sounds farfetched..." He paused, glancing down at Lightning Song for a brief second. "But I can show you."

Alphys sighed and crossed her arms. "Let's s-see it then."

Sans reached into his hoodie to pull out the book he had taken from Lightning Song's library: The Chosen One. He handed it to the rather confused lizard and stuffed his hands in his pocket. "I took this from Lightning Song's library. It doesn't explain much about where she's from, but it gives you an idea," he explained, taking Lightning Song in his arms again. "I'll need that book back later tonight, though. We're having dinner together tonight at Toriel's. It's important that you come."
