A/N-Okay, so I know some of you are probably getting a little antsy for another oneshot, and I'm trying to work on another one. Hopefully I'll have it out to you either later today or maybe tomorrow. However, this plot kept bouncing around in my head and wouldn't leave me alone until it got written. This is actually based off of my oneshot "New Girl" for the challenge. A couple of people suggested that I expand it, and I hadn't really planned on it, but once the idea got put in my head, it wouldn't leave me alone. Damn plot bunnies bouncing around. You don't need to read "New Girl" to understand this. If you have read it, then you know what's going to happen. I'm just going into more detail about what happened, and I'm going to go past the end of "New Girl". I'm kind of interested in where this story's headed myself. All the LWD stories that I've read where Casey gets pregnant always have them doing just fine, so I don't know if you guys are going to get pissed at me for screwing things up.

Casey paced back and forth in the living room, desperate for Derek to come home. It was December of their senior year, and Derek was captain of the hockey team. She knew that was why he was late coming home from practice; he had probably stayed to talk strategy with the coach. Still, she was getting rather antsy. Even though their parents had approved of their relationship, she would rather have the impending conversation before they got home. Finally, she heard Derek pull up. She rushed him as soon as he walked in the door.

"We need to talk, now," she said as she dragged him up the stairs.

"How about a shower first?" he wiggled his eyebrows suggestively.

"No," she replied, leaving no room for argument. She led him to his room and shut the door. She also turned the music on, hoping to drown out the noise of their conversation, just in case Lizzie and/or Edwin were listening at the door.

"So, what's up hot stuff?" Derek questioned. He watched Casey pace around his room, much like she had in the living room. Derek wrapped his arms around her legs as she passed, and tried to lighten the situation. "Working out at a time like this?"

"Joking at a time like this? You're so irresponsible." She pushed his arms off her and resumed her pacing.

"Okay," he said, sounding a little offended. "It's kinda hard to know not to joke when you won't even tell me what's going on."

She said nothing and just shoved a small plastic stick in his direction.

"What's this?" he asked, sounding slightly scared. "It's not what I think it is, is it?"

She looked at him. He sighed. "You wouldn't be showing me this if it was negative, would you?" She shook her head, tears glistening in her eyes. "Shit," he mumbled. "I thought we were okay. You said you were on the pill."

"I was," the tears started to fall from her eyes. "It's not 100 effective. I guess we're the lucky oddball chance."

"You're sure?"

"Yes, Derek, I'm sure. The proof is right there in your hand. Plus, I've been sick all week, my boobs hurt like hell, and I haven't had my period in six weeks." She was still pacing and crying.

He pulled her down to sit on the bed next to him, and wrapped an arm comfortingly around her. She leaned her head on his shoulder. "It'll work out, okay? I promise, we'll figure it out. I'm assuming you want to keep it, right?"

"You don't want to?" she asked him, sounding slightly angry.

"I didn't say that. It'll be hard."

"I know. But we'll figure it out, right?"

"Right," he confirmed. He kissed her on the forehead. "I love you."

"I love you too."

------------

That night at dinner, neither Derek nor Casey said much. Nora and George looked at each other from opposite ends of the table; they both knew that something was going on.

Nora tried to get them to confess something, anything. "So, Derek, Casey, what's new? Anything at school, anything between you two?"

Casey's head shot up, a panicked look in her eye. She immediately glanced at Derek, who shook his head no, just barely. Casey was the only one to notice it, but that's okay, since that was who it was intended for. "Everything's fine, nothing's new. I guess we're just tired, homework and all that stuff."

"Hmm," Nora said, letting it go for the moment. She would get them later, when the younger kids weren't around.

They finished dinner in silence, then Lizzie moved into the kitchen to do the dishes. Everyone else sat in the living room to watch TV for a little while. Casey sat at Derek's feet, but she kept fidgeting. She seemed unable to find a comfortable position. Derek reached down and began to rub her shoulders, whispering, "Relax, or the 'rents will suspect," in her ear. She calmed down, at least in her body movements. Her eyes still jumped around the living room though.

George put Marti to bed after a little while, and about an hour and a half later Lizzie and Edwin followed her. Then Nora turned off the TV and faced Derek and Casey.

"What's going on? We know there's something, and when you don't tell us, we start thinking the worst."

Casey looked down at the floor, tears already beginning to form in her eyes. Derek spoke, knowing that she wouldn't be able to form a coherent thought at the moment. "It's probably better that we let you think, because then you don't know for sure and you can't freak out on us."

"Derek, tell us. Now," George said in his lawyer-voice, the voice that Derek knew he only used when he meant business.

"I'm pregnant," Casey whispered. Derek was sure that they hadn't heard her, he had barely heard her and he was sitting right above her.

"What Casey? You need to speak up," Nora said, confirming Derek's thoughts.

Casey cleared her throat, then said, a little louder, "I'm pregnant." She finally looked up, and the tears began to spill from her eyes.

"You're kidding, right? We put you on the pill, you can't be pre…" Nora started to say, unable to finish the last word.

"It says right on the box that it's not 100 effective. Of course it's our luck that we're the odd point-something percent," Casey responded, not looking her mother in the eye.

"Oh, baby, I…I don't know what to say," Nora began to cry, and reached out to hold Casey's hand.

George had not said anything yet, but Derek could see him getting angrier and angrier.

"What are you guys planning on doing?" she asked, looking back and forth between Derek and Casey.

"Abortion is definitely out. I just don't think that I could do that," Casey said quickly, looking at Derek.

"Yeah, I agree. That's not something I want. And, well, I did kind of figure that we would get married one day and have kids, so I mean, we're going out of order and skipping ahead a couple of years," Derek said, reaching out and squeezing Casey's knee.

Nora began to cry even harder, pulling Casey into a tight hug. "Oh, Casey, honey, we support whatever decision you make." George looked enraged at this, and finally exploded.

"Support their decision? What is your problem Nora? They obviously think that they're adults, they should be treated like adults. They should move out, get jobs, join the real world. They think they're grown up enough to raise a child, let them prove it!"

"George, it's not like they planned this!" she yelled back at him.

"No, but they aren't taking care of it either."

"Like hell we aren't! We've decided to keep it, it sounds to me like we're taking care of the situation just fine." Derek stood up to yell at his father. This was the first time that George realized how close in height him and his son had become.

"You can't take care of another human, you can barely take care of yourself! How are you going to raise a child?"

"I don't know yet, but we'll find a way. This child is a product of love, and I would die before I gave him or her up! Come on Casey, we're obviously not welcome here." He grabbed her hand and pulled her to her feet. She looked terrified and turned back to her mother for support.

Nora acted quickly, trying to diffuse the situation. "Wait, wait, you can't go out there tonight. You'll never find a place to sleep. Come on, how about we all just go to bed, sleep on this idea, and talk again tomorrow?"

Both George and Derek grumbled an agreement, and went to their separate bedrooms, while Casey just fell into her mother's arms and cried. "Mom, we can't do this. I'm scared. What if we fail?"

"Shh," Nora said, trying to get her to calm down. "Everybody's scared when they find out they're pregnant. You freak out, you're convinced that you can't do this, and that even trying is going to send this poor kid to therapy for the rest of his/her life, and then you buck up and do it. Once you start feeling that baby move around inside of you, you become a little more sure of yourself. You'll do fine. It won't be easy, I'm not going to lie, but this baby will know love, and that's what's important."

Casey nodded slowly, then kissed her mother on the cheek and went up to her room. She was terrified about the upcoming breakfast conversation the next day. She hoped her mother would be able to calm George down.
