Sans wanted to smack his face at the fact that Asgore didn't catch on. But he managed to withhold that action (or he was just too lazy to do so right now), and he answered Papyrus, "Well then, I guess that means he has a...[color=yellow]baaaaa[/color]d memory?" Skylar couldn't help but laugh at the pun, and Sans grinned widely.

However, the joviality in that grin faded quickly when a certain person appeared.

Skylar and Sans looked to see a new person came into the picture. A boy with a manly bandana and a saccharine exterior appeared and said that he wanted to join them in order to learn more about the Underground for school. Flowey who was still in Papyrus's hands, seemed to have that look of recognition, before its mouth contorted into a small, devilish grin. 

Sans stared at Chen silently not letting his emotions show, while Skylar answered with a hesitant and polite smile on her face, "Ye-Yeah, life's pretty strange," She couldn't say why exactly, but she had a feeling that this person was dangerous...A feeling of deja vu, perhaps? Considering what happened earlier, she wouldn't put the feeling past it. 
Sans and Skylar looked to Undyne and Papyrus when they spoke up. The shorter skeleton chuckled, "Sure, I don't see why not, bro. The more, the merrier," 

*~*~*

Skylar wasn't sure why Sans agreed, but she wanted to speak up and give a reason as to why this guy shouldn't come. But she never did get the chance. David brought up a valid point, flew up to her, and helped her down. She held onto David (making sure that it was tight enough so that she didn't fall, but not tight enough to hurt the poor guy). When he whispered to her, she nodded and she answered him, whispering just as David did, when he was done talking, "I'm glad I'm not the only one who got that feeling! Something about him is really off. We'll have to keep an eye on him," She then realized something and she introduced herself before David landed, "My name is Skylar," 

After David landed, Skylar watched as he flew back up, and she mumbled "I better stay here and wait for the others," She noticed that she was standing amongst a patch of yellow flowers. They seemed to have been well taken care of. She also noticed among the yellow flowers, was a small light. She reached her hand out towards the light out of curiosity, and after a brief flash and a feeling of determination, the light had disappeared. 

*~*~*

Sans noticed how different Chen's behavior towards Papyrus was in comparison to Frisk's and Skylar's when they first met him. He held back a derisive snort, and ignored Flowey as it shouted towards David and Skylar "[color=yellow]You all know you're going to die, right?![/color]" He wanted to throw Flowey using his blue magic, but he didn't want to do so in front of Papyrus and the others. 

When David came back and Chen asked the bird monster, Sans spoke to the kid casually with a shrug, his hands in his pockets, "Huh, you're quite prepared...and determined to do that assignment, aren't ya?" He shrugged and continued "I'm sure you can hitch a ride with Mettaton, kid. I think our bird friend here, will...[color=yellow]egret[/color] carrying another person down while they're tired," He then turned and said "I'll meet you guys down below," He walked into the trees and disappeared, only to reappear at the bottom of the hole, with Skylar. 

He looked to said girl, and he noticed that she was looking towards the entrance of the ruins. He asked "'Sup kiddo?" Skylar mumbled quietly, "I hear noises ahead...Listen..." Sans remained silent and he heard what Skylar was talking about. There were people ahead, and they were talking. But they were too far away to tell if it was Frisk or not...
