Sulley and Y/N led the girl with Cheerios in his bedroom. The girl picked them up and ate them as she entered.

"Okay, all right. We're making a nice little area for you to--" Sulley started as he made a little bed out of a newspaper and Cheerios.

Then they heard giggling and looked to see the girl made herself comfortable on his bed.

"No. Hey, hey, that's my bed! You're going to get your germs all over it," Sulley protested.

"Sulley, its fine," Y/N insisted as the girl went further into the bed.

He just sighed then pointed out, "Fine. My chair is more comfortable anyway."

As they started leaving, the girl yelled, making them stop.

"What?" Y/N asked.

The girl spoke in fear as the two monsters saw she was looking at the closet.

"It's just a closet. Will you go to sleep?" Sulley told her.

The girl then pulled out a picture she drew of two very familiar monsters.

"Hey, that looks like G/E/N and Randall," Y/N said then realized, "They're your monsters."

"You think they're going to come through the closet and scare you. Oh, boy, how do I explain this? Uh, it's empty. See?" Sulley said as he opened the closet.

"Ah!" the little girl squealed in fear and hid under the covers.

"No monsters in here," Y/N assured.

To prove that point, Sulley went in and looked inside then turned around.

"Well, now there is, but I'm not going to scare you. I'm off-duty," Sulley assured as he stepped out and closed the door.

But the little girl was still unsure, making them sigh.

"Okay. How about we sit here, until you fall asleep?" Y/N suggested.

Sulley pushed some cinderblocks in front of the closet, sat on them, and Y/N sat on his lap. The girl just looked at them.

"Go ahead. Go to sleep. Mm-hmm. Now. Now...go," Sulley tried then said with motions, "Uh, you...go...to...sleep."

He imitated snoring, making the little girl and Y/N giggle until the girl fell asleep. Sulley sighed in relief as they looked at the sleeping child.

"Wow, Sulley. You're really good with kids," Y/N commented.

"Me? I'd say the opposite. You came up with the idea to make the bear sing to calm her down. How did you know that would work?" Sulley asked.

"When Mike and I were little, our teacher did that to our class when we were upset. It calmed us down and made us laugh," she answered.

"That was a good idea. By the way, I'm sorry we couldn't do our date night tonight," he apologized while gently taking her hands.

"Don't worry about it. Tonight was a night I'll never forget. No matter what happens, I know I'm good as long as I'm with you," Y/N explained.

As they stood and headed for the door, Y/N thought of something.

"Hold on, Blue Boy. I want to try something," Y/N said.

"What?" Sulley asked.

Y/N looked at the child and walked toward her, reaching to touch her head.

"Wait. Are you sure?" he wondered, stopping her for a minute.

"Yeah. I don't think she's dangerous," she answered.

He hesitated for a minute, but nodded eventually. She reached out and touched her head, lightly rubbing it. The girl snuggled into the touch and took her hand to cuddle it like a teddy bear.

"I guess I'm sleeping here tonight," Y/N chuckled then offered, "You can have my room if you want."

"Thanks. Good night," Sulley told her as he tucked her in.

"Sweet dreams," she whispered.

They kissed then Y/N laid down and went to bed. Sulley quietly went to the door and closed the door with one last look at the girls sleeping on his bed. He walked up to Mike with a new thought.

"Hey, Mike, this might sound crazy, but I don't think that kid's dangerous. Y/N thinks that too," Sulley pointed out.

"Really? Well, in that case, let's keep it. I always wanted a pet that could kill me!" Mike said sarcastically at first then yelled at the end.

"Now, look. What if we just put her back in her door?" Sulley suggested.

"What?" Mike questioned.

"Mike, think about it. If we send her back, it's like it never happened. Everything goes back to normal," Sulley said.

"Is that a joke? Tell me you're joking," Mike asked.

Sulley shrugged, saying that he wasn't.

"Sulley, I'd like to think that, given the circumstances I have been extremely forgiving up to now, but that is a horrible idea! What are we going to do? March right out into public with that thing? Then I guess we just waltz right up to the factory, right?" Mike explained.

Sulley wasn't paying attention since an idea formed in his head as he looked at the love seat's pattern.
