They were going to a dinner party at the Dreemur's. Gaster had heard about a human that fell down, and the king and queen took them in. He... Hadn't heard great things about them- not bad things, but they locked themselves in a room and refused to leave. He was carrying Papyrus, and holding Sans's hand.

"Will we meet the human?" Sans asked, looking at his father.

"I don't know, Sans. Perhaps, but unlikely. Asgore told me they haven't left the room they locked themselves in." Gaster told them.

"Why?" Papyrus asked, tilting his head.

"They're... Untrusting of monsters, one would assume. Toriel told me that they looked around your age, Sans. But I do not know. If they are your age Sans, they've probably been told horror stories of us monsters, it would be logical for them to be afraid." Gaster told them.

"But dad-" Sans started, "don't you hate humans? Why do you seem so calm about them?"

"They're a child. They were not in the war. They haven't hurt anyone yet. I do not blindly hate people because of where they came from, Sans. That would be like saying you hate a dragon monster because their parents burned down a village, they didn't do anything." Gaster explained to the young skeleton.

"Oh.. Okay." Sans mumbled, nodding.

"I bet we'll be friends!" Papyrus declared, happily, "and I'll show them that monsters are nice, and we'll be happy, and close, and be friends forever and ever!"

"S'not gonna be that easy, Paps." Sans told his younger brother, "if they locked themselves in a room because monsters scare them, they probably won't be easily befriended."

"Your brother is right, Papyrus. They may not want to be friends, so please do not be upset if they ignore, or even be rude to you." Gaster warned his youngest son.

"Fine.... But I'll try my best!" Papyrus smiled brightly.

"That I am sure of." Gaster smiled, and chuckled a bit. "Ah. We are here, Sans? Do you want to knock?"

"Yeah!" Sans nodded quickly, and ran to the door, knocking as hard as he could.
