Thanks again, @DTUndertale. I decided to combine the two concepts I requested. It's mostly fem, but with the return of Colorblind Error. Real quick, though, let me write how I think they met Destiny.

Nightmare walked into the living room where Error slept and saw something laying on him. She stepped closer and saw a maine coon cat laying on his chest and curling around his arm, as if they were hugging it. He was still sleeping, but it looked like he fell asleep hugging back. She decided to let sleep in and let the others know.

When Error woke up, he introduced them to his "beautiful angel" , but the cat, or Destiny, hissed whenever they got close to him and smacked their hands away. Still, they never saw him this happy, so they let Destiny stay. She began to trust them more, but would still be on momma cat mode if Error was sleeping or if he was having an panic attack.

Let's move on.

"I dOn'T uNdErStAnD." Error said as he pet Destiny, who was sitting in his lap and hugging his arm."You've done a lot for us. It's only fair if we at least get you something." Killer explained."YoU dIdN't KiLl Me WhEn YoU sAw Me." Error said."That's not enough! What do you like?" She asked.

"I dOn'T rEaLlY wAnT mUcH mOrE." Error said. Destiny smacked him and meowed."It'S nOt NeCeSsArY." Error told her. Destiny meowed again and nuzzled against his chest."What's not necessary?" Killer asked, hoping she could get something out of him. Error sighed."To SeE cOrReCtLy." He replied."What do you mean? Of course you need sight!" Killer said."I dO hAvE sIgHt, I jUsT hAvE a HaRd TiMe SeEiNg...." Error mumbled something and Killer didn't hear him."Seeing what?" She asked."...CoLoRs." Error finally said. This time, it was loud enough for her to hear and her sockets widened.

"What?" She asked in surprise. Error stood up and walked back to his room, which Nightmare showed him this morning. It was pretty spacious and there weren't any windows. He used his strings to make a hammock in the corner and grabbed a fuzzy blanket that was in a small pile before climbing the wall. He crawled onto his hammock and let Destiny jump onto it before crawling onto it and laid down. He placed the blanket down and Destiny laid down on top of Error's chest, curling around one of his arms and purring softly.

Make your own ending. Is it considered RP?
