She said she was tired, but she didn't sleep.

Mono stayed up that night, thinking of things she couldn't remember. Or, well, not thinking of things she couldn't remember. She knew the doctor, and he wants her soul, but she forgot. Just like she forgot everything else. That's why she was wanted, why Papyrus wanted to kill her, and why Sans kept her so hidden.

She was endangering him, yet he refused to change his mind about hiding her in his home. Of all the absurd laws in the underworld, sheltering refugees is recognized as treason. The consequences for which are less than civil.

"Sans?"

"What?" He grumbled. He sounded groggy.

"Am I your friend?" She asked.

"You're a pet."

"Then why do you-"

"You found the human didn't you?" Sans said before rolling over to face her. "Don't think that I didn't see your prints in the snow. You led me right to the kid."

"You knew?" The pup said with shock in her voice.

"You're still a dumbass for going out while Papyrus was in town, but you did good. That's what you're here for. Now go to sleep." he said before rolling back over.

So if she got killed then he wouldn't be able to find humans as easily. Mono was disappointed that it didn't have more depth than that. No one has friends here, she said it herself. That's the way it had always been; but then why did it suddenly sound bad?

"What if we don't need to find humans anymore? Would I still be a pet?"

"...Go to sleep, mutt."

"But y-"

" d-" -he sighed- "I said go to sleep..."

The next morning, Mono was...not in the house. She was in what appeared to be a dark room with concrete flooring. There were bars that kept her from the rest of the room; almost like a cell. On the floor was a note left by Sans, so she walked over to read it.

*You thought I would let you off that easily for going out? Yeah, no. Don't do that again. Have fun in solitude, mutt.
P.S: I'm not soulless, I know it gets cold in that shed. Go to the dog house if you start freezing. I don't want to find a pupsicle when I get back.

Mono growled. Great, now she was locked in the shed until Sans returned, and who knows when that will be. The shed was cold though. Her jacket could only do so much since it only covered her upper half. Now she wished she actually dressed like the other dogs. Dog pants sounded sooo ridiculous before, and tedious since she wouldn't be able to remove them without help, now she wished she had them.

In the corner of the cell was a bowl filled with some dry dog food. It smelled pretty descent, but tasted horrible. How could dogs eat that stuff? Without much else to do, she took shelter inside the dog house; which wasn't much warmer than the rest of the shed.
