Summary: Post!Apocalypse. Lucifer is made human and the Winchesters grudgingly agree to look after him. Maybe he can really learn to love, especially when he meets a girl who happens to live close to Bobby. Please R&R!

Disclaimer: I don't own Supernatural or its characters. I only own my OC.

A/N: Lucifer/OC! WOOOO! Just thought I've give the Devil a little loving after he's humanised because of the whole Apocalypse thing.

Hope you enjoy and please feel free to review!

Learning Curve

Chapter One: Adjusting

Castiel watched as Lucifer sat on the sofa staring apparently into space. He felt for his brother, and despite everything Lucifer had done during the Apocalypse, he was serving his punishment now, and Castiel and Gabriel were trying their best to be there for him. They found he liked to watch the rain from his bedroom window. He liked to write in a diary about what he was feeling. Dean kept cracking jokes about him being emo or something, whatever an emo was. But right now, the poor guy just looked so lost, so unsure that Castiel's chest tightened at the sight.

"Lucifer?"

The former Devil looked up and sighed shakily, trying to hide the fact that he was crying. Castiel couldn't bear to see him hurting that way. Dean hadn't waited before embracing Castiel into human life when he'd been afraid, and Castiel wasn't about to abandon his brother who was alien to humanity. He'd gained so much more respect for humans in the few weeks he'd been one of them, and Castiel and Gabriel could both see that he was trying so hard.

"Lucifer, it's alright." Castiel promised, "I'm here...Gabriel's here...Dean and Sam are here...Bobby and Crowley are here..."

"I know." Lucifer choked out, "I'm so sorry."

Castiel sighed and wrapped his arms around his brother, rubbing his back soothingly and whispering soft assurances into his hair. And Lucifer, not really knowing how to control what he felt anymore, just broke into sobs, which pained Castiel beyond belief to have to listen to.

"Alright..." He soothed, "Alright, shhh..."

Lucifer cried into his brother's shoulder and Castiel looked up to see Gabriel standing by the doorway, concern etched all over his face. He moved forwards slowly, kneeling by Lucifer and wrapping an arm around him too. To see Lucifer, the former Devil crying his eyes out like this was just heart-wrenching, not to mention worrying.

"Gabriel?" Lucifer asked, Gabriel smiling softly and holding his brother close.

"I'm here, Luce...I'm here." He soothed, "We're all here for you, it's okay."

"Look at him." Bobby sighed, "We gotta get him outta the house, guys."

"Why don't you get him started working in the yard with you and Dean?" Sam suggested, Dean nudging him hard, "What? It was just a suggestion."

Lucifer currently sat in the kitchen with his head buried in his arms, not really knowing what else to do with himself. He'd cried that morning again and Castiel didn't know if he could take much more adjustment. He was really struggling, and Lucifer struggling meant that things really weren'/t good. The others were in the hallway spying on him, while Crowley and Gabriel were sat reading in the study.

"Why don't you all just leave him alone?" Castiel snapped, "Can't you see he's having a hard time here? I think that we should find him something constructive to do, but give the poor man time to get used to this world and how we live."

"Alright, baby." Dean whispered, "Alright."

He pulled Castiel close and kissed his cheek, the young former angel blushing and leaning into the touch before going to speak to his brother. Dean watched as Castiel sat by Lucifer's side and rubbed his arm gently, the former ruler of Hell looking up with red, tearful eyes. The brothers looked at each other and Castiel began to promise Lucifer that it was alright and that he'd learn things in time.

"I think having him working in the yard wouldn't be such a bad thing..." Bobby whispered, "I mean, he'll learn the importance of working for a living, he'll be able to learn to buy his own stuff...which means he can learn to socialise."

Dean licked his lips and bit the bottom one, scrubbing a hand over his face while he thought about it. Lucifer had to learn to do all these things himself and Bobby and the Winchesters knew they all had to help him with that. And that they'd do. Nothing was as important as family; that had always been Dean, Sam and Bobby's rule, so why could it not apply to the angels in the family.

"Alright." Dean said, "You go tell him then."

Bobby walked into the kitchen and sat at the table, looking at Lucifer who was currently being cradled in Castiel's arms, telling him that he could work in the yard and he'd start to learn more about living with humans. Lucifer nodded gratefully and rested back against Castiel, the younger man continuing to hold him. And that's what everyone loved about Castiel. He was just so caring and so compassionate that he didn't care how long it would take, but he would sit and comfort someone until they felt better. He'd done it through the war with Dean's nightmares in the Apocalypse and he continued to do so now.

Lucifer stood up, going to get a drink of water to clear the lump in his throat before meeting Sam and Dean in the doorway. He smiled weakly, muttering an 'excuse me' before moving past them and heading up to his room. He'd be sat looking out of the window again as usual, but Sam watched Castiel sit at the table and cover his face with his hands, nudging Dean who turned to look. The older Winchester thanked Sam with a nod and headed towards the kitchen, sitting down beside him and taking his hand.

"You okay, baby?" Dean asked, Castiel nodding his head, "It'll be okay...c'mere..."

Pulling Castiel towards him, he leaned forward and kissed his forehead, Castiel winding his arms around him and burying his face in his neck.

"Love you, Dean."

"Love you too, Cas."

Four Weeks Later

Lucifer stood under the hot sun, pulling his shirt off and revealing a toned, bare torso, a fine line of hair running from his belly button downward. He ran a hand through his blonde hair and sighed, taking a drink of water before returning to the hood of the car Bobby had asked him to work on. He went to pick up a wrench when he saw a pair of long, smooth legs, his eyes trailing further up before they rested on a beautiful brunette with thick, long, wavy hair, small, pretty features yet with big green eyes. He couldn't take his eyes away from her; she was just so gorgeous. She was wearing a light pink dress and it flowed around her legs, outlining her waist and breasts beautifully. She turned her head and caught him looking, the two sharing a small smile before she carried on walking, Lucifer watching her go.

He felt something in his chest; like a fluttering and he wondered what that was. He also felt something harden in between his legs and he suddenly realised he had an erection. He was attracted to the woman who'd just walked past; incredibly attracted. He saw Dean approaching and tried to hide it, the hunter noticing the hint of embarrassment in Lucifer's eyes. He caught a glimpse of the woman walking away and chuckled, patting the former Devil's shoulder.

"You got the hots for her, Luce?" He asked, Lucifer nodding shyly in response, "Y'know, she lives two blocks away. She passes this house every day. You should talk to her."

"And say what?" Lucifer asked, "I can barely hold a conversation with you guys, never mind a woman who I..."

Dean felt a little bad for the dude. He was probably far from a virgin but when it came to actually being with a woman he really cared about, he was. He'd have to be a real gentleman and take her out, treat her to things, compliment her, and, if things went the way Dean assumed Lucifer wanted them to go, make love with this woman.

"I'm not sure what her name is but we know where her house is. Seen her coming away from there once or twice." Dean said, "Next time she passes, I'll see if Gabriel can use his mojo to get you two together...y'know, like making her drop her keys or something and you can pick them up and give them to her. It's a great way to start."

"You...you'd do that?" Lucifer asked, "For me?"

"Yeah. Course I would." Dean replied, "Bobby says you're done for the day, by the way. He doesn't want you getting too worked up."

"Thanks, Dean."

"Anytime."
