Lost and Found

-Four-

The estranged brothers stared at one another, Castiel just grabbing Lucifer and pulling him into a hug.

"How've you been, Castiel?" Lucifer asked, a little unnerved by the way his brother shook in his arms, "Cas?"

He pulled back to see Castiel with tears falling down his face, grimacing before pulling him close again. He hated to see his brother so upset; he always had.

"Shhh..." He soothed, both of them breaking the hug when a soft voice sounded from the living room.

"Papa?"

Castiel wiped his eyes and smiled at Leila who was looking at Lucifer with confusion before he went over to her and picked her up, kissing her cheek. Finally, she'd get to meet one of her oldest uncles.

"Come in, Lucifer." He said softly, Lucifer stepping inside and taking his shoes off before closing the door, "Leila, I want you to meet someone very special to Papa, okay?"

He brought the little girl forward and Lucifer smiled at her, Leila acting a little shy as she always was with strangers.

"This is your Uncle Lucifer..." Castiel began, turning to his brother, "Lucifer, this is your niece, Leila-Marie Winchester...she's two, just turned, and she's very sleepy because she just woke up from her nap."

"Wow," Lucifer said softly, "Nice to meet you, Leila-Marie."

"Hi, Uncie Luci..." Leila breathed tiredly, "You Papa's big brother or ickle brother?"

Lucifer chuckled.

"I'm his big brother." Lucifer replied, smiling at the little child who was placed on the floor and toddled away into the living room, "Damn, she's tiny..."

"Yeah, she's always been a smaller child." Castiel said softly, "Come in and sit down..."

Lucifer did and grinned when he saw Leila curled up on the floor, Castiel sighing and picking her up.

"C'mon, baby..." He whispered, sitting her on his knee and rocking her gently before looking to his brother, "Would you like a coffee?"

"That'd be great, thanks." Lucifer replied, Castiel nodding and kissing Leila's head, popping her on the floor which made her cry.

"Papa!" She wailed, reaching for Castiel who picked her up again and rested her on his hip.

"Come and help me make Uncle Lucifer a cup of coffee." He said softly, winking at his brother who winked back and followed them into the kitchen.

He looked to Leila who rested against his shoulder, walking her over to her little cloth playhouse. It was pink and had little windows with blue window boxes and a blue door, a yellow thatched roof with a tiny chimney on top. It was such a beautiful little thing and Lucifer smiled as he saw it.

"Why don't you go and make us some lunch, huh, baby?" Castiel asked, "I bet spaghetti would be great since it's Uncle Lucifer's favourite."

Leila toddled into the playhouse and sat down, Castiel waiting for the usual response as he smiled at Lucifer.

"Spatteggi coming up, Papa!" Leila called, Lucifer laughing as she did, "Would you like some fench fies? Or some meabowls?"

"French fries or meatballs, Lucifer?" Castiel asked, Lucifer biting his lip.

"French fries sound great, Leila." He called, "Thanks, sweetie."

"Your welcub!" Leila replied, both men chuckling as she talked to herself whilst making the pretend lunch.

"You still have three sugars, Luce?" Castiel asked, Lucifer nodding in response, "Milk?"

"Thanks."

"Here, Uncie Luci!" Leila squealed, toddling out with two plates and spoons in her hands, "Here, Papa!"

Castiel turned and smiled pouring the coffees for himself and Lucifer before accepting his baby girl into his arms.

"Thanks, sweetie," He whispered, kissing her forehead as she turned to Lucifer, "This smells delicious."

"Thanks, Leila." Lucifer said sweetly, the little girl smiling shyly before she headed for the living room, breaking into a little jog which made Castiel chuckle, "God, she's a beauty, Cas."

"She's so stunning..." Castiel replied, "Dean and I...we love her to death."

"How is Dean?" Lucifer asked, watching his brother's lips curve into a dreamy smile, the two of them placing the plastic cutlery by the sink.

"He's good, thanks." Castiel said softly, "What...what brings you here?"

"Um...Michael's kinda pissed at me, I guess." Lucifer replied, "He's just taken over that business and screwed us all over in the process."

"Zachariah? Uriel...? Raphael?"

"All of us."

Castiel sighed and shook his head, beckoning his brother to follow him as he headed for the living room, where Leila was transfixed on the TV. But suddenly she shuffled uncomfortably and started to cry, Castiel grimacing and going over to her.

"What's the matter, sweetie?" He asked, Leila gasping and clutching onto him, sobs wracking her tiny body.

Castiel looked to Lucifer who was grimacing himself, then looking back at his daughter and holding her close.

"What's wrong, Leila?"

"Me wee-weed..." She sobbed, "I really sorry, Papa! I twied to hold it in, but I couldn't!"

Lucifer bit his lip and watched as Castiel pressed a gentle kiss to his little girl's head, rubbing her back again to try and calm her. Lucifer wasn't a complete sap, but to see his little niece so upset and to hear her apologising for having an accident just broke his heart.

"Baby, if you need to use the potty you need to tell me, okay?" He said softly, "Don't be sorry. I know you're trying to be a big girl and you're trying to hold it in, but you need to tell me, alright?"

"Is Papa mad?" Leila asked, Castiel's heart breaking at the sight of her tearful eyes.

"No, my little angel...Papa's not mad at all." Castiel soothed, "Come on. Let's change you, huh?"

"I sorry..." Leila whimpered as Castiel lifted her into his arms.

"Don't be sorry, it's okay..." Castiel whispered, looking to his brother, "I'll be right back."

"No, take your time." Lucifer replied, "She okay?"

"Yeah." Castiel replied, kissing Leila's head and taking her to change her.

Lucifer looked at the photos that were on the walls and on the coffee table, on the mantelpiece and on top of the TV, some of just Dean and Castiel, going from when he remembered them as being lovestruck seventeen year olds right up to now, and the majority of them being of the two of them with Leila. He'd found his favourite straight away. A family photo hung on the wall in the middle of two that were just of Dean and Castiel.

In the picture, Dean sat with an arm around Castiel, while Castiel held a very tiny Leila in his arms who couldn't have been more than six months old. She was so small, and Castiel was gazing down at her with such loving eyes it made Lucifer want to tear up. As for Dean, he was grinning down at his baby girl, and Leila was smiling right back at them, her hand wrapped around Dean's finger. It was such a beautiful photo, and Lucifer knew that Dean and Castiel would savour that forever.

As Castiel returned with Leila, he smiled, setting her on the floor only for her to toddle to Lucifer with her arms outstretched, Lucifer opening his arms in return and enveloping her in a hug, pressing a kiss to her head.

"Uncie Luci?" She asked, Lucifer smiling in response.

"Yeah?"

"How comes I never seened you before?" She asked, Castiel biting his lip and looking to Lucifer with eyes that were begging him not to tell her the truth.

"I've been on a really, really long vacation." He said, Castiel smiling with relief.

"Oh!" Leila beamed, "A vataton! Papa and Daddy took me on a vataton to Disney World! I metted Buzzie from Toy Story! I yuv Buzzie!"

"Wow!" Lucifer replied with as much enthusiasm as possible, "I bet that was exciting!"

"It was eciting!" Leila giggled, "Papa gotted me a piccie taked with Mickey Mousie!"

Castiel chuckled and found his wallet, showing Lucifer the picture of Leila who was only one and a half at the time cuddling up to Mickey Mouse.

"I go get my teddy!" She cried, running towards the kitchen and leaving the adults alone.

"Her language is just unbelievable!" Lucifer grinned, "Damn, she's a clever girl, huh?"

"Oh yeah," Castiel replied with a sincere nod, "I've never heard a child talk as clearly as she does at this age. You can understand practically everything she says and she can engage in conversation for such a long time. The doctor couldn't believe it herself."

"We got a genius in the family it seems." Lucifer smiled, watching as Leila toddled her way back in, breaking into a run only for Castiel to catch her as she almost fell.

"Steady, Leila..." He breathed, picking her up and sitting her on his knee.

Lucifer finished his coffee, smiling at his baby brother before rubbing his hands together.

"I...I'd better go." He said softly, "I've just rented an apartment...Gabriel's got all the details you're gonna need."

"I see." Castiel said softly, standing as Lucifer did before following him to the door, "It's been lovely to see you again."

"And you." Lucifer replied, pulling his brother into a hug and kissing his temple before addressing the child in his arms, "And it's been lovely to meet you, Leila-Marie."

"And you, Uncie Luci!" Leila squeaked, the pair watching as Lucifer headed away before closing the door and returning to the living room.

Castiel couldn't believe that Michael would turf the others out like that. It wasn't in his nature at all, and he knew that he and Gabriel would have to get to the bottom of what was happening before anyone else got hurt.
