That effectively ruined my night," Kate said walking towards the bed. Rick observed her shivers and shakes as they pulled back the blankets. He grinned at her as they both climbed in, turning in for the night.

"It's horror, if it doesn't ruin your night then it didn't do its job," he replied while turning out the light.

"I know but…I don't know, those kind of movies remind me of Hales."

"Oh God," he said sitting up. "Wh-why would you–Kate why, why would you say that."

"I'm being honest! She's that prime movie-demon-child age. She could totally do it," she said pulling the blankets up to her face.

"I hate you, I can't believe you said that."

"I can't believe you made us watch that movie."

They paused for a second, looking around, thoughtful of the movie again and then their daughter asleep upstairs.

"I'm gonna fall asleep first," Kate said turning around, nestling herself lower in the bed.

"Yeah, well I hope she comes for you first." As soon as he finished she pulled her arm out and slapped his butt, a simultaneous snicker spitting out of her.

For most of the night they both slept soundly, undisturbed. But around 4 o'clock, little Haley Castle managed her way down the steps and into her parents bedroom. She looked like a miniature Kate, the only minor difference in her lips–those were Rick's. She inched towards the bed, going for her mother, calling out to her in a timid whisper.

"Mama? Mama," she said at the side of the bed. Seeing her efforts make no change, she jumped ahead and got up on the bed, on top of Kate, and held her cheeks. Her hands so tiny and cold managed to wake Kate, eyes slow in opening, but widened as she processed what was happening.

"Hi mama," she said smiling. Though her expression conveyed mere surprise, internally Kate was fraught with panic, fighting the desire to scream and flip her child off the bed.

Kate…don't. This is your child. This is your baby. She came out of you. This is not a demon. She came from your womb. This little nugget came from you.

She convinced herself for a good minute before she took any action, but even then she moved with some reluctance. "What's wrong sweetie?" Kate said sweeping her hand through Haley's hair.

"I can't sleep," she said with a pout.

"Yeah? Well, now you and me both kiddo. Come here," she said carrying her to the middle. Haley slid herself almost all the way under the sheets, exposing just her eyes. Kate giggled at her, and kissed her forehead before going back to sleep.

"Night-night baby," she said.

"Night-night, mama."

The next morning Kate got up for an early run before going through with the family festivities for the day. When she got back she went to shower, before preparing breakfast for everyone. Rick was slower to wake, but when he did, he turned to face Haley still sound asleep next to him. He rose up with caution, staring down the person lying next to him.

"Kate?" he asked poking the little face. "Did they finally come? Is this what they did to you," he asked while ripping the sheets off of her. She woke with the rush of cold to her skin, her eyes cracking open with frustration, just like Kate's would.

"Daddy!" Haley shouted. Kate heard her from the living room and stretched a smile out of glee, secretly hoping Haley had scared him too. When she made it to the doorway, she saw him with a look of disbelief as the two both sat up in bed. He looked over at wife, then quick to his daughter, then back again to Kate.

"I thought it was you–I thought they–"he said pointing upwards.

"Yeah, no, daddy. But now mama knows what kind of movie to get next time she wants to freak out daddy, right Hales?"

Little Castle nodded as she rubbed her eyes to remove the sleepiness from them, Rick and Kate chuckling with joy watching her.

"I'm sorry for waking you up sweetheart," he said pinching her cheek. She just smiled at him before getting up to give him a hug.

"Oh come on baby, don't hug him," Kate started. "Don't you think he deserves something mean? Like…I don't know, a tickle fight?"

Kate knew just how to rally her daughter, because in a split second Haley started it out, with her mother to follow suit afterward. Rick allowed himself to fight back weakly, but after a little while he turned it around, securing them together as he tickled them.

If this wasn't bliss, Rick and Kate didn't know what was.
