Casey ran into her room, feeling Derek follow her. She threw herself onto her bed, burying her head into her pillow crying. Derek laid down next to her, and rubbed her back. "Case…it'll be okay. Screw them no one can tell me whether I can be with you or not…"

Casey could tell he was over the top angry, "We're 17….we can't raise a kid" she finally let the truth get to her and rolled over facing Derek,

Derek pulled her closer, so that her head was on his chest and he held her, "Anything's possible, we'll make it work and be the best damn parents" I think?...

"No we can't…. we're brother and sister Derek do you realize how wrong this is?" she was still crying silently.

"Step! No blood at all. I don't care what anyone else thinks, you are my girlfriend, this is my baby and that's all that matters" he kissed her forehead.

She slowly looked up at him, tears made her face glitter, "Everyone won't approve of us….my mom, she hates me" this is wrong Casey. Wrong!

He looked down towards her, "She doesn't hate you…she's just having a hard time with the fact you're her little girl growing up. And those who don't approve minds well find a life and get out of ours"

Casey knew she could trust him, so she decided to go with it. Maybe they could make this work, though the thought of a baby had hardly sunk in yet, she still knew Derek would stick by her side the whole way.

The next day was Saturday; Casey had woken up early so that way she could go to the doctors. She'd quickly gotten dressed and did her makeup, when heading downstairs doing the best to avoid her mom and George. She'd found no one was up yet, but when she walked into the kitchen she noticed Derek standing there drinking a glass of orange juice. He looked up at her and smiled, "Ready to go?"

Casey gave him a weird look, "What…?"

Derek laughed, "To your doctors appointment there silly!" he put his orange juice in the sink and walked out of the kitchen heading for the front door.

Casey following, questioned this, "Why are you going with?" she never thought Derek would actually go to the doctor's with her.

"Because I want to…?" he looked at her, spun around and threw her, her coat and was walking out the front door before she could answer. She followed him out the door and into the car. They drove to the doctors office, with Casey wondering what to do about the Toronto Theater cast contest and slowly felt depressed again not to mention she was about to go sign up for a pregnancy doctor. They soon arrived at the doctors and Casey went up to the front desk. Derek saw her filling out paper work with the lady at the desk who looked fairly friendly, so he decided to sit down at a chair nearby. He began thinking, what if Casey leaves me if I'm not a good enough dad? What if I mess up? We better not get into a fight or she'll be done with me for good. By the time he was done thinking, Casey had taken a seat next to him. He looked at her; her face was pale with no expression. He knew she was scared she just wouldn't show it. In fact she wasn't the only scared one, he was too surprisingly. Derek Venturi scared? Psh; he could just hear all the guys in his head once they found out he got a girl pregnant and to make matters worse, his step sister especially. Casey stood up as soon as the doctor came out calling her name. She looked at Derek worriedly, "Will you come in with me?" Not that he didn't plan on coming in but he thought Casey wouldn't want him in there, he already caused enough problems. He nodded his head and followed her and the doctor into the patient room.

He's a guy?! No way is he going to look at my Casey down there; Derek pondered jealous thoughts as he saw the doctor tell Casey to undress and put a gown on. He soon enough left the room, and Casey quickly got changed and soon enough stared at Derek. Derek looked up towards her as she spoke, "Are you nervous…?"

He smiled at her and sighed, "As much as you are"

She smiled that Casey Macdonald adorable smile and the doctor walked through the door. An hour later after the doctor had examined everything he needed to, he told them they needed to make an appointment for an ultrasound for next month. To both Casey and Derek's surprise the baby seemed exceptionally healthy although it was extremely tiny at the moment since Casey was only 3 weeks along. The doctor stared at both of them, "Scared at all?"

Casey looking tense tried to smile, "You have no idea"

The doctor laughed, "You'll be a wonderful mother and" he turned towards Derek, "You'll be a wonderful father"

Derek and Casey both blushed, and soon enough the doctor left leaving Casey getting dressed quickly and both running out the patient room into the main desk and out the exit. They entered the parking lot, where Derek swooped Casey up in his arms, with her legs around his waist and tickled her. "DER-EK!" she laughed playfully.

"What? Can't I tickle the most beautiful person?" he smiled while holding her.

Casey put her arms around his neck, "Stop sucking up." she moved the hair out of her face.

Derek laughed, "This would be sucking up" He than leaned in and kissed her passionately and set her down on the ground, grabbing her hand and walking to the car. As they both got into the car, Derek driving and Casey next to him, Casey looked at him.

"Der…" she sounded concerned. Just ask he won't get mad. Just ask

"Yeah Case?" he answered as he turned the car on and began to drive away.

"Will you promise me something?" she looked out the window thinking what to say next.

"Anything" he turned at the stoplight and kept watching the road.

"Promise not to do drugs…ever again?" she knew this was going to cause a argument as she saw the anger come in his eyes.

"Casey I wouldn't do that to you, you know that. I've learned from my mistakes so stop judging me" he was getting stressed by the moment at the sound of drugs.

Casey looked at him, now she was edgy. "I'm not judging you, I'm just afraid"

"Afraid of what?" he slammed on the brakes at the stop sign.

"Afraid that you'll leave baby and I for drugs, or someone prettier, smarter and better than me" she could feel the tears, another mood swing had come.
