Handplates Gaster x Subject 3! Clever! Tween! Reader

You and Papyrus were still sleeping when you both heard the lights come on. You both stiffened and stretched. You yawned and blinked a couple of times as Papyrus yawned as well. "Subject 2 and 3." You both turned to see Gaster with Sans next to him. "Subject 1 will be sharing your cell."

You gulped before Sans entered. Papyrus noticed your fear as Sans sat down. Gaster left as you shivered. Papyrus crossed his legs before Sans's eye glowed. "*alright. I need answers (y/n)." Sans growled. You perked as Papyrus silently summoned a bone attack.

"*why is he so nice to you?"

You looked down and just as you were about to say 'I don't want to talk about it' you heard a blaster get summoned. "*and I don't want to hear excuses..." Sans growled. "Sans! You can't force her to tell you her secrets!" Papyrus said angrily.

"*well I-"

"He saved me."

The two perked as you pulled your legs close and took out your heart locket. "About eight years ago Gaster saved me from my death. That's all I'm telling you." You said as you got your locket on. "*that's it?!" Sans asked. You nodded slowly.

Papyrus looked at your locket before he saw Sans's eyes were dark. "*that can't be it..." Sans growled. "I'm not telling you anymore..." You growled back. Before anything else happened, Papyrus broke Sans's blaster with a bone attack. "Sans. Stop." Papyrus ordered. Sans growled before he leaned back.

Gaster removed the helmet as you held your head. "No progress. Must be stress." Gaster said as he took notes. "Gaster... why did you save me?" You asked as you looked down. Gaster perked as he turned to you. "I saved you since I saw something in you." Gaster answered.

"What did you see?" You asked. "Does this have to do with Sans?" Gaster asked as he wrote down some notes. "...yes..." You muttered as you tapped your fingers sheepishly. "I will talk to Sans. If he is this curious, he should be asking me." You nodded as you slid off the chair.

"Also, do you have any feelings towards Subject 2?"

You yelped as a bright blush was painted on your face. "Heeeey! Look at the time! I better get back to my cell!" You said as you speed walked away. Gaster chuckled softly as he wrote down notes.
