He really is McDreamy

Derek has been living here for five days and it's wonderful, he's such a great roommate, he makes me dinner every night, he does the laundry, and he is completely professional at work with me, well sometimes he'll forget and call me by my name rather then Dr. Grey, but other then that he's pretty perfect, and my mornings always start with him in boxers as he makes breakfast.

"Hey Der, Dr. Craven." I said walking over to the nurses station, where Derek and Dr. Craven stood.

"Meredith, Meredith, how many times do I have to tell you, call me Chase, and hello to you too." Chase said, smiling at me while I rolled my eyes, then his pager went off he looked down. "Shit! I gotta go. See ya later Shep you to Mer." He said smiling as he walked away.

"Bye Chase. Hey Mer." Derek said, giving me his dreamy smile.

"What have we got today?" I said, smiling at him.

"Today we have a patient with a cerebral aneurysm, it formed after a small car accident and didn't show up on the MRI right away. We can go to the patients room as soon as our intern shows up." He said, handing me the patients chart.

I opened the chart and looked through it, as I was I heard a very girly voice say. "Hello Dr. Shepard, I'm your intern today." I looked up and saw her, she looked familiar, she had brown hair and brown eyes.

"Hello Dr..." Derek hesitated, not knowing the interns name.

"Grey. Dr. Lexi Grey." Then my eyes grew wide as I realized why she looks familiar, she's my other half sister. "But you can call me Lexi, Dr. Shepard." She added in a flirtatious voice, my half sister who doesn't know about me, is hitting on Derek, my Derek, well not my Derek, but my roommate Derek.

"Well Dr. Grey go ahead to room 284 and I will be there in a minute." Derek said while looking at me concerned he obviously realized how tense I became when I heard her name.

"Ok, see you there Dr. Shepard." She said in another flirtatious voice.

"Mer what's wrong?" Derek said, confusion throughout his voice.

"Noth... nothing I'm... I'm fine." I said, trying to convince him.

"Mer-" I cut him off.

"Derek I'm fine, I'm-" I was cut off by Lexi's voice, down the hall.

"Dr. Shepard the patient is waiting." She yelled to Derek, while winking at him.

"Meredith you don't look fine, beautiful, but not fine. What's wrong?" He said in a very concerned voice, completely ignoring Lexi, while rubbing my cheek.

"I'm... I just feel a little light headed, and tired from being on-call last night, but I'll be fine come on we have a patient to go see." I said trying to avoid telling him what's wrong.

"Do you want to lay down for a bit? I can page you when I need you." He said, still very concerned.

"I..." Hmm if I lay down it means less awkward time with my half sister. "Ya ok I'll go lay down for a bit."

"Go lay down in my office and test out the couch you pick, it's way better then the on-call room beds." He said smiling at me.

"Ok thanks Derek." I said as I took off toward his office.

I walked to his office and dropped on the couch, he was right it's way nicer then on-call room beds, I helped him pick it out when he was redecorating and this is my first time on it. I took a deep breath and my mind switched and went on to the real problem. Lexi Grey my half sister is working in my hospital, why here, she could work anywhere, but she chose here. Thatcher knew I worked here yet he still let her work here, he's probably trying to torture me. I slowly started to drift off.

I wake up to the door opening, and then I hear a very soothing voice say my name. "Meredith?"

"Do you need me?" I said lifting myself up from the couch.

"Not yet I just wanted to see how you were doing." He said, coming over and sitting on the couch, where my head just was.

"I'm fine, but how long have I been gone?" I said trying to change the subject.

"About fifteen minutes, but lets not avoid the subject here, tell me what's wrong." He said, already knowing me to well.

"Fine I'll tell you." I said as I laid back down with my head on his lap as I looked up at him. "You know our intern today, Lexi Grey, well... she's my half sister, and I don't even think she knows I'm alive and if she does I seriously don't think she likes me to much. She works here in the hospital that I work at and today she's working with us and I'm really not fine because, my half sister is our intern." I said, I think I gave him to much information.

"Ya I kinda figure there was some tension between you two when she said her name and you kind of tensed up." He said, looking down at me, while he played with my hair.

"Ya well that's the tension, she's my half sister." I said, deciding it was probably best to leave out the fact, that it really pissed me off, when she was hitting on him.

"Well I guess it's a good thing I got Chase to switch interns with me today, so instead we have George today, and I talked to her resident when he puts her in Neurology it will be with the other Neuro Attending so when we aren't working." He said smiling down at me. Then our pagers went off. "Now we have to go do surgery on our patient, and then our shift's are over and we can go to Joe's." He said as I started to get up.

"Derek you're amazing." I said, because he really is, and he is constantly proving why he's called McDreamy.

"I know." He said as he held the door open for me.

"Too cocky." I said, and he laughed.

We went to the scrub room and scrubbed in and walked into the OR. Just before he made the first incision he said. "All right everybody. It's a beautiful night to save lives. Let's have some fun." It has become my favorite saying in the OR. Right after he cut through to the brain, Derek asked me to take over, I clipped the aneurysm and closed up the skull without a problem, he actually let me do the whole surgery. I was on a surgery high, my day got so much better.

We left the OR and went into the scrub room, and as we were scrubbing out I said. "That was amazing!"

"Ya it was, you did an amazing job in there." He said smiling at me proudly.

We scrubbed out, got changed, and went over to Joe's, waiting for everyone else to come and join us for a few drinks before we went home. We were sitting at the bar, with a beer each, and Derek turned to me and said. "We should be celebrating your first surgery done all by yourself."

"No! No celebrating! Don't you remember what happened last time?" I said, ok so I'm all for the celebrating especially if it leads to where it lead last time, but we can't he's my boss, and my roommate, and bad divorce.

"Yes I remember where it lead to last time in fact, we should celebrate more often, more celebrating I say." He said giving me a sexy grin.

"No we-" before I could finish I was cut off by the same voice that ruined my morning.

"Dr. Shepard! What a coincidence seeing you here." Lexi in another flirtatious voice, we're across the street from the hospital how is that weird.

"Hello Dr. Grey." He said sounding not so enthusiastic, as he was trying to turn his attention back to me.

"Dr. Shepard please call me Lexi." She said, obviously not taking the hint.

"No I'd prefer not to." He said, still trying to give her the go away hint.

"Can I buy you a drink then." She said, still not giving up.

"No thanks, Mer you ready to go." He said smiling at me.

"Umm ya everyone is taking to long anyway and we have to be up early tomorrow." I said getting up with him.

"You two are together?" I hear Lexi's voice say.

We completely ignored her as we left, we got into my car and Derek said. "Are you sure that's your half sister I think she's a little slow to be related to you." We both laughed, as we drove home together.

I've got this feeling that there's something that I missed, I could do most anything to you... Don't you breathe!

I didn't really like this chapter and I rewrote it like seven times and this is the best I could come up with. At first I wasn't sure if I should add Lexi or not but there's going to be a reason for her later (Plus I really wanted Derek to reject her).

So this Chapter was about well Lexi being introduced and to show how great Derek is and that Meredith was a tiny bit jealous that Lexi was hitting on Derek.

I'll try to sneak on again and update soon. The next one will take place 2 ½ weeks after Derek's moved in so ya. Read, Review and hopefully Enjoy.
