"Sorry, what?"
"I said go away."
"I know, but before that-"
"I said I-"
"I know what you said Papyrus." This time, Sans was the one whose head was pointed downwards. He sighed. "Why didn't you tell me?"
"I... don't know."
Sans was also still frowning, but... his face had changed. He wasn't sad, something Papyrus could tell by his response: "What do you mean, you don't know?! Why don't you trust me?! This has been going on for who knows how long and you've only decided to tell me until know, and you won't say why!"
He was going to berate Papyrus more, but then he heard more sobbing. "I-I'm sorry, I didn't mean to make you cry... I... just care about you a lot, Papyrus." He was ashamed at he turned to look at his miserable friend. "I do. And, when you don't tell me things, I worry that I'm not a good brother. I guess I got a little too stressed there."
Papyrus tried to stop shaking. "I-it's okay. Y-you are a good brother S-Sans. I-I r-really don't know why I d-didn't t-tell you... I'm sorry..."
Sans was now hugging him, a somber look on his face, and a soft voice. "Oh buddy, you didn't do anything."
Papyrus didn't believe that statement, which he made clear: "B-but Undyne-" he argued with sadness.
Sans wouldn't let him finish his thought. "We'll figure it out."
Somehow, Papyrus smiled.
It was 2 hours since the incident with Undyne, and although Sans told him she would come over later, Papyrus completely forgot. So when his fishy friend entered the house, he dropped his pencil he was drawing with, and immediately looked down, as if that would hide him from the woman.
She sat down at the kitchen table. "Why am I here?" Papyrus could tell she was irritated.
Sans looked at his brother with a smile. "Well, Papyrus, why is she here?"
That made Papyrus scowl. Sans was the one who called her here. He should be the one to answer. Besides- apologizing was hard. She wasn't going to accept it anyway.
"Well?" Sans repeated.
The upset monster looked at his boots as he let out an uncomfortable grunt. He could do this. With no more thought, he opened his mouth and almost mumbled, "I wanted to apologize."
Nobody said anything. They were waiting for him to continue his apology.
The tall body's eyes were still fixated on his shows below. He was going to have to talk. So, finally, he shared his "speech" he had worked on. His tone was dry, and he sounded like a completely different person. "I don't know why I did that," he started off, "What I do know is that you're not dumb. Not at all. In fact, I'm the one who's dumb, for telling you that. I don't know what got in to me. What I'm trying to say is that you're a wonderful person, and I'm sorry."
Undyne's mouth was open, but no words came out. She was gaping, looking straight at the apologizer.
"...You don't accept it, do you?"
Undyne shook her head quickly, which didn't really do anything considering the fact that her associate wasn't looking at her. "No, that's not it at all! It's just...your voice."
"Oh, that."
Undyne waited for him to provide an explanation, but she realized he wasn't going to, so she asked something. "Why does it sound like that?"
Papyrus didn't know what to say, or how to say it. At first, he just said, "Eh," then, "I got a problem."
The pirate pal tilted her head. "Problem?" she chimed.
"Problem." Papyrus said nothing for a second, thinking about how stupid he just sounded. That wasn't even a complete sentence. Nonetheless, he was understood anyway, and he had to keep going. "Yeah, it's like... well, first, I sound like that because I'm upset. And second..." Papyrus took a deep breath. "I don't know for sure, but I think... I think I'm depressed."
Undyne didn't know how she felt. She turned to look at Sans. "Sans, did you know this?"
Sans nodded. "Yeah, he told me after you left."
She frowned. "Papyrus..."
"Yeah?"
"Papyrus, I forgive you. Just tell me if you need anything, alright?"
"Alright. Thank you."
Somehow, Papyrus couldn't smile.
