Sans nearly laughed at Papyrus, always striving to be a good model for the royal guard while he himself didn't really care. Before he could say anything to his brother he felt Undyne patting his skull in what he thought was a condescending manner. He was once again stopped from making any comments however by the arrival of two individuals. One he recognized as Asriel, but the other was unknown to him. Waving to the two as they approached, Sans moved away from Undyne. He watched with a grin as the unknown figure stepped forward, introducing themself as Draco. He listened to the pun and couldn't help but laugh.<br/><br/>"Nice to meet you Draco, I'm Sans. And that," He pointed over his shoulder to Papyrus. "Is my literal bone-head brother, Papyrus." The skeleton turned to his brother, the grin still on his face. "Hey Pap, can we keep her? She seems really pun-tastic!" He asked before giving his attention back to Asriel and Draco.<br/>"So what brings you two all the way out here?" He didn't mind at all, it was just another distraction from his post.
