"Case, come on! You're going to be late for your first doctor's appointment!" Derek yelled up the stairs.

"I'm comin! Be patient!" She said as she began her descent.

He held her hand as he escorted her to his car. He even opened the door for her.

After he climbed in, Casey said, "Derek, you have become such a gentleman! I'm so proud of you." and then she kissed him.

"It's just the beginning, babe." He said as he started the car.

They arrived at the doctor's office and only had to wait five minutes before going into the exam room.

They were holding hands, and Casey could feel him shudder.

"What's wrong?" She asked.

"Nothing, I just hate doctors' offices...they just look so clean and fragile."

"Sweetie, it's okay, you're not even the one who the appointment's for! All you need to do is sit back and relax."

He sat back in his chair as Casey put her feet in the stir ups. Soon the doctor came in.

"Casey, I'm Dr. Mallory Samson," She said extending her hand, "And you must be Derek."

He nodded and shook her hand.

"So you took a pregnancy test and it was positive?" She asked.

Derek laughed, "Try seven pregnancy tests."

Casey scowled, "Yes, they were all positive."

"Okay, I'm just going to check this out and we'll see how far along you are."

The doctor did all the necessary procedures.

"Okay, it seems like your baby is perfectly healthy and you are about 10 weeks along. The due date is actually going to be December 24th...Christmas Eve! That's going to be a busy week!"

"Ooo! That's so exciting!" Casey squealed and looked over to Derek.

Derek smiled, "That's great, honey."

They finished up the appointment, headed back to the house, and Casey climbed into bed to watch some TV while Derek was getting ready to go out with Sam.

"Derek." Casey called out.

"What is it?" He asked as he came back into the room.

"Do you promise to never leave me or the baby...even if it's scary?"

"Case, come on," He said as he plopped down next to her and stroked her hair, "What brought this about?"

"I'm watching this show, and her husband left because he couldn't commit to a child!" She said with her eyes tearing up, "And I think it would be more likely for you to leave because we aren't even married!"

"Case, baby, it's going to be fine, I will never leave you, ever."

"Promise?"

"Forever and ever."

"Thank you...and I'm sure if the baby could talk, it would be thanking you too."

Derek hugged her and headed out for his night hanging out with Sam.

He got into his car and pulled up to Sam's.

"Yo, D, I was thinkin how bout we hit up a couple bars tonight, get wasted, then crash here and play video games."

"Okay, whenever I wanted to do that, you always said no."

"I know, I just miss ya, man! Let's live it up before you have a kid!"

"Sam, I don't know, I don't think Case--"

"Dude, you are so whipped! Come on!"

"How about we just stay in and play video games or something?"

"Ugh, fine, but only because I'm afraid if you get in trouble with Casey, I'll be in trouble. And I always knew Casey was scary...but pregnant Casey is much scarier."

"I'm with ya there."

They went inside and played Halo 3 until midnight.

"Well, Sammy, I better go, Casey is probably freaking out, especially since I left my phone at home."

"We will still have to go clubbin some night!"

"Definitely!"

Derek drove home slowly to observe the quiet, because he knew that his life wouldn't be as serene anymore. He slowly opened the door and walked inside the house.

"DER-EK! Where were you?!" Casey shrieked.

"Hun, I told you I was going to Sam's. We played video games."

"Oh...yeah, I forgot...i fell asleep and forgot where you were...sorry." She said solemnly.

He brought her close to his chest, "No worries, babe."

"I love you." She said looking up at him.

"I love you too, even though you're crazy." He laughed.

She snuggled close to him, then went upstairs for bed.
