"We were going outside," You said, your patience quickly leaving your body as your eyes narrowed. UGH. THE AUDACITY OF THIS MAN.

"ew, but it's sunny." He narrowed his eyes right back at you, before throwing a disgusted look out the window, and then a small glance at Dream. However, you guess it must have gone unnoticed since Dream said nothing.

"Well, sunny weather can be quite nice," Cassidy said, seemingly unfazed to Nightmare's intimidating negativity.

"yes, but (y/n) could get a sunburn. that wouldn't be good. you two should go alone." As the words left his mouth, he walked over and grabbed you by the wrist, yanking you away from the confused group behind you. You shook your hand in an attempt to get away as you protested, but before you had the chance to slap him he had teleported both of you away, and into the library.

Dizziness overcame you as your vision went dark, only to reappear again as you found yourself in the library. You looked around trying to comprehend what just happened, which didn't take very long, as you immediately slapped him across the face hard.

Nightmare obviously didn't expect this, and he stumbled backward with his skeletal hand pressed against his marked cheek. He looked back up at you with an expression you hadn't seen on him before - hurt, scared. A wave of guilt overcame you as his eyes met with yours, but it didn't last long. Not even a millisecond later his eyes (or, well, the visible one) narrowed back to their harsh expression. He wiped his cheek one last time.

"well jesus, that wasn't nice," he spat, glaring at you.

"You really wanna talk about 'not nice' right now?" you spat right back, your arms crossed as you scowled at him. He rolled his eyes and plopped down on a couch. You wanted to yell at him. You wanted to scream at him. To be honest, you wanted to pick him up and yeet him off the face of the earth.

But, you couldn't. You just couldn't. Because you couldn't get that expression out of your mind. The scared one. God, why do all of these skeletons seem like injured puppies?

You sighed, letting your arms drop and your posture relax, as you sat down next to him. "What do you want? Really, I was about to go outside with them."

He looked up from fiddling his fingers, to give you a mildly perplexed expression. You had seen this expression on him before once or twice. Most of it was sarcasm, but this one looked genuinely confused. "what, you're mad i teleported you here? they're both really annoying anyway, i figured i did you a favor."

"Uh... Okay, you might be right," you snickered. "I may have dodged a bullet there. Sunny weather isn't my favorite." You smiled, your brows upturning. Even if you didn't want to admit it, you weren't a huge outdoors person. Spending time with Geno outside was always fun, and you did look forward to spending more time with Cass and Dream. But, regardless, you still felt just as good here.

Nightmare's brows raised, and he smiled arrogantly as he brought his arms up to rest behind his head. He turned to face you, and his expression faltered. So did yours. Your eyes locked.

...

He turned back around, his face hardening slightly. Your face started warming up like a toaster, and you faced a nearby bookshelf and hugged your knees to your chest as you exhaled. You snuck a glance back at his face. He looked... deep in thought. You had seen this expression on him before as well. You see it on him all the time.

He, like Error, spends tons of time in the library. When he reads, he looks focused. It's almost like he's tuned out of the world around him, and he's genuinely interested in what he's reading. Considering his usually sarcastic nature, seeing him make that expression intrigued you.

When he wasn't reading, he was usually thinking. He could sit and think all day, but he seemingly gets bored too easily. When he thinks, he has a similar focus to when he reads. But there's something a bit different... you couldn't exactly put your finger on what it was. It might be how his browbones are slightly narrowed, his usually harsh eyes relaxed and staring into nothing. He seems to be staring into space, and it always made you wonder what he thought about. Your best guess? You had no idea. Even so, you think it might be nice to know one day. Maybe you could ask him.

His expression now was similar to his thinking one, but less relaxed. He seemed to be working out a problem, trying to figure something out. You didn't know what it was.

His voice interrupted you, and you blinked as you came back to reality. Now that you think about it, you think a lot too!

"so if you don't really like sunny weather, what weather do you like?" His voice was back to it's normal tone, albeit more relaxed. Nightmare normally had an intimidating harshness to his voice, as if he was displeased with everything around him.

"Well, it's not that I don't LIKE sunny weather, it's just not my favorite," you spoke calmly, facing back across the couch at a familiar table. "I really like rain though. Cold rain is alright, but warm rain is nice. It's like swimming in a tropical ocean, just without the salt, sand, and glaring sun."

"hmm." Het let out a small hum in response, and you fell back into silence.

A silence filled with both of your thoughts. It was quiet, but you could hear yourself speaking. You could almost hear your own chattering ideas and thoughts conversing inside your mind, their voices bouncing off the walls. You could almost hear Nightmare's too, but you didn't know what they were saying.

You wonder what he is and was thinking about. You wonder what that expression was earlier. You wonder what other expression you will get to see. You wonder what Cassidy and Dream were doing. You wonder if it will rain anytime soon. You wonder when you'll get to go home.

You wonder a lot of things.
