Frisk's sweet laughter rang in Sans' skull, a lulling and very welcomed sound. He just held her all the closer with a grin and massaged a gentle bony hand against her scalp. He hoped to hear more of it now that they were mostly in the clear.

He hummed in thought at her question, moving his hand to rub her back instead. "Hmmm, he'll probably be disappointed, but I don't think he'd mind." Although Sans didn't expect to be sleeping anymore. He was exhausted, but not sleepy. After something like this, he wasn't the type of guy who could just sleep it off. But that didn't mean Frisk couldn't be comfortable, and he silently hoped she was comfortable with him snuggling her like this.

As if on cue, Papyrus opened the bathroom door and peeked over the edge of the second floor railing, shower cap still laced over his skull. He smiled down at the pair and gave a quiet thumbs up, not wanting to disturb them after they'd finally gotten through to each other. Sans looked up to return the gesture, giving a tired grin of his own as the taller skeleton wordlessly crept to his room.

Sans let out a quiet, but content sigh as he completely relaxed, bony fingers still subconsciously running the length of Frisk's back. There was a peaceful silence in the house now, the television just a blur of quiet background noise. Not loud enough to be annoying, but not completely ignorable. Still, even with that, Sans just wasn't comfortable. Without the sound of voices in the air, he could only remember the silence that echoed through the house when Paps hadn't been there. It was disturbing.

And that's what lead him to his next joke.

"Why was the skeleton sad," his voice was quiet and almost tentative, not really expectant of an answer or feedback," he was very [I]bonely[/I]." He didn't laugh at that one, not because he didn't think it was funny, but so he wouldn't disturb Frisk too much as she sat there with him. He was more than used to staying up for days at a time with only power naps to sate his need for rest, but Frisk didn't seem like she was.

He continued on quietly, joke after joke, a bad pun thrown in here and there, just something to keep him from thinking about before. 

And even through the haze of emotions and exhaustion, Sans' mind came back around to his own issue at hand. He gazed down at the human in his arms and let out a small sigh. He could do it. No, he would find a way to stop Frisk's aging, or at least slow it down so they could all live together and then die together as well. But if slowing it down wasn't enough, then he'd rather he die before her. He couldn't stand the thought of living without her there. Frisk was a part of his home, of his life, one so great that nothing could take her places.

Hold her just a bit tight, Sans muttered softly,"I'm going to protect you... No matter what." He let his eyes drift closed, dozing, but still awake enough that he could respond if need be.
