Chapter 21 – The Weight Of Us

Song – Way To The Future By Katie Herzig

"What do you think about the future?" Derek asked as he turned his head to face me on the pillow.

"What do you mean?" I asked a little stunned by the question. I was taken a little off guard. I didn't really think of the future. I just took day by day. The Future seemed scary.

"When you think about the future, what do you see?" he asked pulling a piece of hair behind my ear.

"I don't know. I see you, and I see Charlotte and that's all that matters. Right?" I asked looking at him.

"Right." He said smiling.

"Why are you smiling?" I asked giggling.

"I love you." he said kissing me on the lips.

"I know that." I said laughing.

"You and our children are my future." He said smiling.

"Children? Like multiples?" I asked confused and frightened.

"Charlotte will need siblings." He said laughing.

"I...think we should go to work." I said getting out of bed.

"Urggg I don't want to!" Derek said rolling under the covers.

"Come on Derek! You cant avoid Mark and your sister forever." I said hitting him with the pillow.

"I can try." he said sighing. The baby monitor went off and I knew what that meant.

"Come on Charlotte is up." I said pulling the covers off him.

"Urggg fine!" He said slowly getting up.

"She probably needs a change too." I said as he exited the bedroom and headed to the nursery. As he went to change Charlotte and get her ready for day care I decided to take a shower. It felt so fresh and relaxing on my skins the droplets of water pored down on my face. I suddenly felt a pair of muscular hands being placed on my shoulders.

"Hummm...that's nice." I moaned.

"Don't mind me joining you?" He breathed into my ear in a husky voice.

"Don't mind at all." I said turning around to kiss him passionately.

"Mmm that's nice." He moaned out. I giggled.

"How about some hot shower sex..." He said grabbing my breasts.

"mmmm sounds delightful." I said moaning in pleasure. He quickly pushed me against the shower window kissing and discovering every part of my body.

"I wonder where you to have been?" Izzie said as we walked down the stairs together giggling.

"There is only one shower." Alex said winking. I blushed.

"Oh lala." Izzia said licking her spoon of whipped cream.

"Don't you guys have work." I said annoyed.

"Unfortunately." George sighed.

"Here is mommy Charlotte." Alex said passing Charlotte to me. I picked her up and kissed her little chubby cheeks. Derek laughed.

"Who wants a ride?" Izzie asked grabbing her coat.

"Me." George and Izzie said both in sync.

"Derek and I'll ride together." I said smiling.

"Sure thing." Izzie said winking as she shut the door.

"We really need to get our own place as soon as possible." Derek said kissing me on the cheek.

"Tell me about it." I said giggling.

"Ready to go?" he asked as I passed Charlotte into his arms.

"Ready as I'll ever be."I said sighing.

"Did your mom's nursing home call again?" Derek asked looking at me with concern. I nodded and grabbed the keys.

"Lets go then." He said holding out his hand. I placed my hand in his as we walked towards the car.

"Meredith!" I heard someone call my name.

"Mark?" I said confused as to why he was talking to me. I thought Derek had scared him off.

"You shouldn't be talking to me. Derek..." I said hesitating.

"He will forgive me. I'm his best friend." he said smirking.

"I'm not so sure any more." I said signing some charts.

"Could you say something to him for me then?" he asked. "I want to no if he's okay? You know...Happy." he said looking concerned.

"You slept with his ex wife Mark." I said looking at him.

"I didn't mean to. Its complicated." He said sighing.

"He was your best friend!" I said angrily.

"I know." he said depressed. "Just...Tell him I'm sorry okay." He said picking up his charts."

"I cant make any promises." I said raising my eye brow.

"You look lovely today. Did I tell you that?" He said flashing a brilliantly white smile.

"Flirting will get you no where." I yelled as he go on the elevator.

"Oh I most certainly disagree!" He said winking as the doors on the elevator closed.

"Stupid Mc Steamy!" I said under my breath.

"Stupid what?" Derek asked as he walked up to me. He took me by surprise.

"Oh, Nothing. Just...Mark." I said sighing. I felt sorry for Derek. Mark was everywhere and he wasn't planning on leaving any time soon. I saw the anger build on his face.

"Son of a bitch." Derek said under his breath. "Why the hell does he keep taking to you! I thought I fought him off. He always goes after my women." He said pissed off.

"Your women?" I ached questioning.

"Yeah! Addison. Now you." he said looking at me.

"I think someone is a little jealous." I said giggling.

"I don't get jealous." He said defensively.

"Yes you do!" I said passing the charts back to the nurse.

"What are you talking about?" he said annoyed.

"You are a very overprotective person Derek." I said walking along side with him as we headed towards the day care.

"How?" he asked clueless.

"You get annoyed every time a man even looks at me. You wont let me do anything that might be remotely dangerous. What if Charlotte gets a boyfriend?" I asked him.

"That's easy. She wont." he said while chewing on his gum.

"Oh, and you are so sure of that?" I asked raising my eye brow.

"Not till she's thirty anyway. No boys before then." Derek said looking at me.

"See! That's what I mean." I said pointing at him.

"I'm a dad Meredith. I'm always going to be over protective over Charlotte." he said smiling.

"Lets just hope she doesn't take after me then." I said laughing.

"God help us." Derek said chuckling.

"Huh." I said poking my tongue out at him. "Your sister is still here." I said changing the topic.

"Don't remind me." Derek said not wanting to deal with her right now.

"She is your sister." I said to him.

"I have four sisters." He said opening the front door of daycare.

"All I'm saying is invite her over for dinner. Then maybe she will go away." I said smiling as one of the staff member passed Charlotte over to me. I kissed he on the head and went to sit down on the bean bags with Derek. Charlotte layed in my arms. She was so perfect.

"Just play happy families and see if she will leave me alone?" Derek asked sitting down with us.

"I suppose so. If we do nothing she might never leave." I said playing with Charlotte tiny hands.

"I guess it wouldn't hurt. But if she calls you a dirty mistress one more time..." he said defensive.

"Yes dear." I said creasing his face with my hand.

"So invite her over for dinner and hopes she leaves then." Derek said falling into the bean bag. He was under a lot of stress lately.

"Its worth a shot." I said bouncing Charlotte on my knees.

"I'll call her then" Derek sighed taking out his phone.

"Ummm... the Chicken is good." Nancy said making conversation.

"Actually Izzie cooked." I said nervously

"Oh." she said as her face dropped with surprise. She probably thought I was a bad mother because I didn't know how to cook prop ley.

"How is everything back home?" Derek asked easing the tension.

"Its good. The practice is doing well. Addison is helping me get more clients." She said awkwardly.

"That's good." I said not sure of what to say.

"Yes." Derek said looking at me and nodding.

So... Charlotte?" Nancy asked as I took a slip of my wine.

"She great. Just starting to smile actually." I said proudly of my daughter.

"That's great." She said trying to smile.

"Yeah she already incredibly smart." Derek said to Nancy.

"Do you plan of getting married?" Nancy asked. I almost chocked on my food. I didn't really think of marriage. I didn't think I was ready for it. Derek and I had only been together for less than a year. It was little early to be thinking about that kind of stuff. I just had a baby. Now marriage. I don't know? A little too fast I think.

"We are thinking about it." Derek said to Nancy. I was shocked be his answer. 'We are thinking about it' What did that suppose to mean. We haven't even talked about marriage. Or was that what he was talking about when he brought up the Future thingy?

I gave Derek a 'your in trouble look' he just nodded. He had some explaining to do.

"Meredith?" Nancy asked noticing my absence response. The monitor suddenly went off. I was saved by a crying Charlotte.

"I'll Get Her." I quickly said leaving the table. Oh how was I going to survive the night?
