Frisk watched as Sans bolted, too stunned to say anything. She wanted to call out to him, shout for him to wait, but by the time she found her voice it was too late. Her arms fell to her sides, and her shoulders slumped. Did he really hate it that much? Had she somehow offended him? Frisk could see how that could be possible, but Sans was such a mystery to her that she wasn't sure what could set him off. Other than harming Papyrus, anyway.

Frisk rubbed one arm and stared at the floor. This was a bad idea. She should have just kept it all to herself. Pretending her emotions weren't there was so much easier than all...this. Whatever this was. 

After a short moment, Frisk inhaled a deep breath and looked up. Toriel was so sure of everything, so wise even in this situation. Frisk would just have to trust her. She'd have to hope that this wouldn't shatter their friendship. Out of anything, that was the thing she absolutely couldn't lose. Not again.

Sighing, Frisk hurried to the stairs, hoping Sans hadn't completely left the ruins without her. She rushed down the stairs and down the hall, only stopping in her mad dash once she turned the corner and spotted the skeleton. She slowed to a nervous walk, happy to see that he hadn't gone too far, but unsure of how he would receive her presence.

She relaxed a bit when she saw his smile. Well, at least she didn't lose that. Walking with him, she didn't expect him to say anything. When he did, her first response was to look at the snow on the ground.

"Sorry, I didn't mean...I didn't think...Uh. Thanks." Frisk looked up at him with a small, shy smile. "Toriel said you might like it." Frisk brought her fingers up to her bangs, smoothing the strands down and readjusting them nervously. 

"How's the uh," Frisk paused, trying to find something to inquire about just to change the subject. "How's the barrier doing?"
