Libby wrinkled her nose after sniffing the liquid in the mini glass. Dean rolled his eyes. "Just drink it," he told her. She sipped the liquid warily. "No. You don't...here. Watch me." Dean brought the glass to his lips, throwing his head back as he downed the alcohol all at once. He shook his head, making a face at the strength of the tequila. "Your turn." Libby eyed the alcohol for a brief moment before copying Dean's actions. She slammed the glass down and started to cough.

"That's disgusting," she told him, pushing the glass away from her. She chugged her glass of water, the taste of the tequila leaving her tongue. "I'll stick with water."

"Buzzkill," Dean grumbled. Libby frowned, sensing that she was the reason Dean was upset.

"I'm sorry. I'm just not used to all of...this." She gestured to the bar around them. "The last I walked the Earth was eighteen years after mankind was created. I don't know the exact year or date, but I can tell you that it's a pretty long time," she explained. Dean nodded.

"Well, at least you're not as clueless as Cas. It's hard having him around others. He doesn't really fit in," Dean replied. Libby sighed, nodding.

"Yes, well I guess the more recent angels aren't accustomed to Earth and its traditions. I met all of the angels from my time, but I never met a Castiel. I suppose he was created after I was sent to keep my father in check." Dean flagged down the bartender.

"We're gonna need a lot more rounds. Keep 'em coming." If Libby was going to talk history of Lucifer and angels, then Dean would need a lot of alcohol in his system to keep him sane.

"You're destroying your liver," Libby said half an hour and twenty-three shots later. Dean downed another shot. Twenty-four shots. Dean slammed the glass down, grabbing another.

"Living the life I do, a destroyed liver is nothing." She sipped her water. A man slid in the barstool next to Libby, eyeing her.

"Excuse me." She glanced over at the man. "I'm sorry, I just want to tell you how beautiful you are." Dean glared at the man, but Libby just blushed.

"Oh, um, t-thank you," she stammered. She had never come across this situation before. No man or woman had ever hit on her. They were all too scared.

"I'm Alex," he told her with a grin. Libby's blood red lips lifted into a smile.

"Li-"

"Not interested," Dean interrupted, downing another shot. He threw a few bills down on the bartop and slid out of his barstool. "Let's go." Dean stumbled, Libby darting out of her seat and catching him just in time.

"I shouldn't have let you drink that much," she told the hunter with a frown. Alex watched, angry.

"Honey, you don't have to go with him if you don't want to," he told her. Libby shook her head.

"No, it's okay. He's my friend." Dean stared at her in confusion.

"Friend?"

"Yes, Dean. I'm your friend," Libby replied. Dean shook his head.

"You're not my friend. I would never befriend Lucifer's child." Libby's eyes widened as Alex stared at her in confusion. She took a quick glance around the bar to see if anyone had heard, but no one seemed to pay them any attention besides Alex.

"Okay, you're wasted. Help me out, Dean. I gotta get you to the car." Libby struggled to support Dean's weight, stumbling with every step. A few minutes later, Libby managed to get Dean over to the passenger side of the Impala. She stuck her hand in his jacket pocket, digging around for the keys.

"Hey, if you wanna bang just take me somewhere else. Not somewhere public," Dean slurred. Libby just rolled her eyes, unlocking the car.

"My innocence is still intact, Dean. I'm not one of your regular whores and I never will be," Libby said, shoving him in the car. "Holy crap, you're heavy. What do you eat?" Dean smirked.

"You really want me to answer that question?" Libby sensed that the answer would take a dirty turn, so she just ignored Dean and shut the car door. Slipping in the driver's seat, Libby tried to remember what Dean had done to start the car. She found a slit that matched up with the key so she shoved the key in and turned it, squealing with excitement when the car rumbled to life.

"This can't be too hard," she said, voicing her thoughts. She backed out of the parking spot carefully before putting the car in drive and speeding off to the hospital to pick up Sam. She had no idea how she knew everything about the car that she did, but she decided to not question it and just take advantage of the situation.

Libby awoke to a knife at her throat and the younger Winchester straddling her waist. Her eyes fluttered opened, meeting the glare of Sam Winchester. "Good morning to you, too, Rapunzel," she greeted. Sam didn't even roll his eyes.

"You're the daughter of Lucifer."

"I am."

"Give me one good reason why I shouldn't kill you." Libby's lips curled into a smirk.

"You need me, Sam. Admit it. You're scared. You can't take down my father because you don't know his weaknesses. I do." Sam scoffed, shaking his head.

"You're just like him." Libby shook her head, the knife just grazing her neck.

"I'm nothing like my father." She grabbed Sam's wrist, snatched the blade from him, and shoved him off of her body. "I was raised by my mother among the humans," she told him, walking across the motel room and setting the blade on the counter. Dean lightly snored in the background, still passed out from the night's events. "I was raised good. I never sinned. Ever." She turned around and faced Sam. "Some would say I was better than Jesus."

"I find that hard to believe." Libby shrugged, running her fingers through her messy hair in an attempt to make it look neater.

"Believe what you want, Sam, but we need each other if we want to stop my father. It's the only way we make it out of this war alive, the three of us and the world." Sam gulped. He knew she wasn't lying but he didn't want to make the mistake of choosing a demon over his family. Not again. Libby eyed Sam, studying him. "What's wrong?"

"This is all happening because I sided with Ruby over my family. I let Lucifer out of the Cage," he told her guiltily. Libby sighed, but shrugged.

"You made a mistake, Sam. Humans make mistakes. I'm not mad. You freed me, my father was just apart of the deal. Apparently we're a package."

"According to Cas, he's circling his vessel. He may already be in his vessel and walking the Earth." Fear rushed through Libby, the thought of her father finding her again sending shivers down her spine.

"Then we'll defeat him." She tried her best to sound confident, but if she couldn't believe it, then why would Sam? "I know it's hard to even think that it's possible, but it is. We've done it once before. We can do it again."

"Dean is Michael's vessel," Sam said simply. Libby nodded. "You know?" She nodded again.

"I was drawn to you two for a reason. You...something in me told me to kill you. Dean convinced me otherwise. And Dean...there was something Heavenly about him. I feel like I need to protect him." Libby glanced over at Dean's sleeping figure, smiling slightly. "He's a handful. I can see it now." Sam chuckled, nodding.

"Oh, you have no idea." It was quiet for a few moments before Sam asked, "So who is your vessel?" Libby glanced down at her body.

"It's mine." Sam furrowed his eyebrows in confusion. "I was raised among the humans, Sam. I wasn't going to inhabit some poor person to make them a backseat driver for all of eternity. God made me a body. This is Libby." She gestured to her body.

"Got a last name, Libby?" She simply shook her head. "Alright, well if you're gonna be hanging around us then you'll need one. What name comes to mind?" Libby shrugged again.

"I never really thought about it." Sam walked over to his computer and opened it up, starting to type. Libby watched in awe as his fingers danced across the keyboard. He typed quickly and accurately without looking at the little squares with a printed letter on each one. He made no mistake when typing. Suddenly a new page popped up with a list of last names.

"I'd go for something for common. That way it's harder for people to pick you out if you're somehow mentioned on TV or online." As Sam slowly scrolled through all of the names, Libby read each and every one. She pointed to one in the W section, causing Sam to stop scrolling.

"There. That one."

"Wilson?"

"Libby Wilson," she said, testing the name on her tongue. Libby nodded, smiling. "Yeah. I like it." Sam nodded, closing his laptop.

"Libby Wilson, it is. Is Libby short for something?"

"Elizabeth. I hate the name, though."

"Noted. Hey, Libby, you hungry?" Libby grinned at the thought of food. The difference between Libby and other angels was that she could blend in with the humans easily. She felt everything they felt. Saw everything they saw. Tasted everything they tasted. She couldn't taste every molecule like Castiel and the other angels. Being raised alongside humans gave her simple human traits, including her love of food.

"Food sounds amazing." Libby stopped halfway out the door. "What about Dean?"

"He'll be fine. Let's go," Sam called out as he headed down the stairs. Libby took one last glance at Dean's sleeping figure. He didn't look peaceful like most humans did. Even sleeping he looked stressed. Libby frowned slightly, but shut and locked the door before meeting Sam at the Impala.

Sam watched as Libby slowly ate her food, savoring every bite. An amused smile found its way on Sam's lips. Libby looked up to see Sam watching her eat. "What?" she asked. Sam chuckled, shaking his head.

"Nothing. I've just never seen anyone so in love with food before." Libby nodded, wiping her mouth with the back of her hand.

"Yes, well, it's been far too long since I've had food. It's even better than I remember. I mean, who knew that a chicken's fingers could be so good?" Sam threw his head back and laughed. "And french fries, I mean, don't even get me started. What are they made from?"

"Potato. They managed to turn something semi-healthy into a rectangle of sodium." Libby grinned at the young Winchester, popping a fry in her mouth.

"Well this sodium stuff is really good." Sam laughed again, finding everything that came out of Libby Wilson's mouth amusing. "Food's changed so much. I mean I had heard of the souls in Hell speak of things like ice cream and pie, but I never thought I'd get to experience it!" Sam slid his milkshake in front of Libby. "What is this?" she questioned, studying the ice cream smoothie.

"It's called a milkshake. Dip your fry in it. It's good, I promise." Libby nodded and picked up a fry from her plate, swiping it through the chocolate ice cream. She eyed it before slowly placing it in her mouth and started to chew. She let out a quiet moan, closing her eyes.

"Heavenly," she stated. Sam chuckled and nodded, dipping his own fry into the shake. "How did humans even come up with such concoctions? And what's pie and--and a cookie?" Sam flagged down a waitress, requesting a chocolate chip cookie and a slice of apple pie.

"You're about to find out." Libby sent him a grateful smile before sipping her Diet Coke. "You like the soda?" She nodded. "You enjoy humanity," Sam commented. Libby nodded again.

"I adore humanity. They were always so kind to me." She smiled sadly as she glanced around the diner. "Now there's so much evil within them and it's so sad." She watched an angry customer storm out of the diner, not wanting to wait a mere ten minutes for a table. Sam sighed, nodding.

"Unfortunately that's how it is, Libby. You're nothing like I thought you'd be." She frowned.

"You expected me to be...evil?" Sam nodded.

"Honestly? Yeah. I mean-" Sam lowered his voice. "You're the daughter of Lucifer and you were locked in Hell with him for thousands of years. I mean who wouldn't think you'd be evil? But, really, you're just a nice girl. You're like..."

"An angel?" Libby finished. Sam nodded. "I suppose I am. I mean my mother, Nadia, is an angel and my father was an Archangel. Technically he still is. He's just a fallen Archangel. It's unfortunate that you thought I was evil, but I do understand where you're coming from." Sam sighed.

"Unfortunately, Libby, people are going to think you're like your father until you prove yourself to him." Libby frowned, but nodded.

"I know," she whispered.
