Lost Identity - Undertale (Sans x Reader)

Questions

"Goodbye!-" Toriel says as she hangs up. You put your phone back in your pocket and have your hand on the door nob when you hear someone shout your name.

"(Y/n)!" You turn to look at the entrance of Snowdin and see someone sprinting towards you as they wave madly. "(Y/n)!"

Holy shit they're fast-

Wait.

"... A-alex?"

* * *

She tackles you to the ground in a hug.

"Where were you? I was so worried!" She says as she squeezes you tighter. "Don't do that ever again!"

"A-alex- how did you- how are you here?"

"I freaked out!" She refuses to let go of you, even as you sit up. "Eventually, I went on a hike looking for you and found your camel-back. I saw the hole, too, and thought you must've fallen down."

"And so you followed me?" As happy as you were to see her, you couldn't help but wish she hadn't come. All she's accomplished is getting stuck down here too.

But you decide to save that conversation for later as you hug back. "Never mind. I'm glad you're here, Alie."

She groans and lets go of you. "No nicknames!"

"Aw, that's impossible." You say, shrugging and standing. You help Alex up and examine what she has on.

She's wearing brown leggings and a grey shirt with sleeves that stop at her elbows. The parts on her knees have yellow and green smears from flowers and grass, and she has muddy Converse on. Buttoned around her neck is a long red cloak that flows gracefully behind her in the non-existent wind. She also has a backpack swung over her shoulder.

"Come on," You say, turning back towards the skele-bros' house and grabbing the handle. "I want you to meet my friends." She raises an eye-brow.

"You? The laziest of all lazy asses? Made friends?" You chuckle and open the door.

"Yup." You head inside with your hands in your pockets. Sans is sleeping on the couch and Papyrus is still hitting things in the kitchen. "Hey, guys?"

Sans opens one of his eye-sockets as Papyrus shouts from the other room.

"WHAT IS IT, HUMAN? I APOLOGIZE, BUT IT IS A BIT DIFFICULT TO HEAR YOU FROM HERE."

Sans looks behind you and sees Alex. He falls off the couch.

"uh— is that—" He says as he sits up.

"Sans, this is my sister, Alex." You say, motioning to her. She waves excitedly. "Alex, this is Sans."

"Wait a second..." Alex stomps over to Sans, picking him up and examining him. One of his pink slippers slides off of his foot and he seems ready to teleport. She gasps. "You're a skeleton!"

"uh..." Sans looks uncomfortable. He glances over at you, silently asking for your help.

*What should you do~?

Nothing. Watch him suffer.

Save him. No one deserves the wrath of Alex's curiousity.

Make. It. Worse. <<<

Choose wisely!*

Sans seems to sense what you're planning, because his eternal smile gets much smaller.

"Yes, dear sister," You say, sauntering over to them and grinning mischievously at Sans. Alex is so tall that you have to tilt your head to see him fully. "He's a skeleton. And I bet he has a skele-ton of things he can tell you about his kind."
