"We didn't need your help." Chara growled, moving to stand only to be stopped by Frisk's hand on her shoulder.
"Be polite." She said before turning to Sans. "Thank you for helping us. It was much appreciated."
"It was nothing. I'm Sans. Sans Gaster."
"I'm Frisk Dreemurr and this is my sister, Chara. Pleasure to meet you." She said, smiling up at him.
"Heh. Been a while, kid." Sans chuckled, recognizing the name. "You grew up fast."
Frisk gave him a confused look before realization hit her.
"Sans?" she asked, slowly standing.
The skeleton shrugged and held his grin.
"That's my name. People tend to use it a skele-ton." he winked, only to be glomped in a hug from the human girl.
"Oh my gods! I haven't seen you in so long!" Frisk exclaimed, hugging the shorter skeleton tightly before pulling away and hold him at arms length. "Still pretty humerus with your puns."
Sans ignored the blue tint that appeared on his cheekbones when the girl hugged him.
"Ahem." Chara cleared her throat, her glare still prominent on her face.
Frisk smiled at the other girl and turned to face her, her hand still on Sans' shoulder.
"Oh. Sans, this is my sister, Chara. Chara, this is my old friend, Sans." Frisk explained, smiling as the two seemed to come to a silent agreement that they didn't like each other already.
After a few beats of silence between the three, Chara stood and yanked her knife out of the table.
"I'm done with this place. We're leaving." She said as she started walking toward the door.
Frisk only smiled after her sister before turning and writing something out on a napkin before handing it to Sans.
"Sorry, she's not very friendly with new people. I gotta go with her but here, my email. Chara won't let me have a cell phone and the house isn't the best place for me but we'll definitely have to ketchup." she winked and placed a kiss on his cheek before grabbing her jacket and rushing after Chara, the two large dog guards following behind her.
Sans could only watch after her, his cheekbones gaining more of a blue tint. He blinked as he felt a heavy hand on his shoulder and turned to see the head guard, Undyne, looking down at him.
"Look, I know what kind of guy you are. You're little brother keeps trying to get into our team so I won't worry about Frisk if you end up dating her. Figured I'd warn ya though. Her parents and her siblings are gonna give ya a hard time. Do some research before tryin' anything with her." Undyne said, grabbing a glass of beer and downing it in one go before slamming the cup on the table and following the others out.
Sans looked down at the napkin with Frisk's email and noticed Undyne had given him a card as well with a number scribbled on the back.
