A/N: This short story is based on the game: Batman: Arkham City, set after the events of Joker's death and at the start of the DLC, Harley Quinn's Revenge. This scene focuses on her false positive pregnancy test and the lullaby she sang the first two lines of her own version of Hush Little Baby which can be heard at Arkham City's end credits on New Plus Game Mode. I also based the title from the fan-made version of her lullaby which can be found on YouTube. Well, I hope you all enjoy this as it's my first fanfiction and please R&R! Thank you!

"And If You Grow Up With His Smile."

"Momma's gonna be so... proud of you..."

"Shhh, there, there."

All around her, there was nothing but darkness that swallowed up every corner of the room she was in. She felt just like this small room; dark, miserable, lonely... trapped. Wherever she looked, finding even a speck of hope was next to nothing. Though it was pretty useless to search for any petty sign of hope. She knew that there was no hope in a place that was darkness. It meant nothing to her now. Everything she aspired for, everything she lived for was no longer here. It was just... gone.

The only source of light that came from within the Steel Mill's room was a lamp that fitted itself on top of a baby's cot. The dimness of the light didn't reach far, but it illuminated the radius around it, focusing on that simple cot in the middle. Only few features of her face shone in the weak gleam. Dried tears that ran down her cheeks glistened, smudging her make up that left her black mascara streaking down. She never bothered to wipe them. Her eyes prickled with redness from hours and hours of crying.

"Hush little baby, don't say a word."

She held the puppet doll in her arms, cradling it as if it were a small baby. But she imagined it as her own little one. And so she had painted its wooden face white, its hair green, its suit purple, and finally leaving a red smile on its face. Scarface was no more. Instead, he became a little Joker Junior. Their baby.

Only there was no baby. There wasn't going to be a little JJ anymore. Scattered on the floor were dozens of pregnancy tests that all displayed a red negative sign. A single negative test lay on the cot. All hopes of mothering the child of her one and only love was never going to happen. She had nothing, just nothing left of him. He was gone and never going to come back. The pain of knowing she wasn't going to have his child tortured her heart, her mind, her soul, everything.

It was her desire to continue his legacy. He knew he was dying as day by day the Titan disease spread through his body. Yet he managed to laugh and think of it as a sick joke. He promised her that they were going to have their own little Joker Junior because he knew he wouldn't live that long. The first time she took the test, it showed a positive and only by that she believed she was pregnant. If she only knew it was a false positive. How helpless she is without her beloved Joker.

Why did he have to leave her? Why couldn't she have his baby? Why did this all have to happen?

He adored Scarface. Sometimes she would think if he loved the puppet a little more than he loved her. Maybe it was just her thoughts, but she came to love the doll as her own. And as she stands over the white cot, with gentleness rocking her 'Joker Junior' back and forth, she sang out her lullaby till the end. A lullaby she would have sung to her real baby.

"Momma's gonna kill for you the whole damn world."
