Here it is! Not late at all...O.O haha. Sorry about the timing, my obnoxious brother is being his normally annoying self and hogging the computer sooo....Okay!

D POV

I flinched as my head made contact with the wall. I would have fought back if he just let up for a split second, long enough for things to clear up again. His teeth were gritted together in anger, his face red. As he held me up against the wall by my throat, Meredith screamed at him.

"Mark! Put him down now!" she shouted.

As he looked sideways towards her, his index finger and thumb dug into the sides of my neck, causing me to let out a quiet whimper. The noise caused Mark's attention to turn back to me, and he smirked. Smug bastard.

When he repeated the action, harder this time, I lost it. My right hand hook caught his jaw and he let go of my throat and grabbed his jaw.

I took this split second of time and dove at him, tackling him to the floor. Mark had always been the one to beat the ever living crap out of me; that was about to change.

M POV

I tried to get between Mark and Derek, but Derek beat me to it. He tackled Mark and hit him in the face; I could see a rapidly-forming bruise appearing. Derek sat up, no longer hitting Mark, and clenched his jaw.

"Now, can we talk like normal human beings or do you want to hit me again?" Derek shouted, out of breath.

Mark went with the second option, his fist connecting with the side of Derek's head. I stepped in then, jumping up and trying to push Derek off of Mark before one of them ended up unconscious.

"Meredith, back up! I've got this!" Derek didn't look away from Mark, though he spoke to me.

"No! Get off him, Derek! And if either one of you throw another punch, I won't forgive either of you." This got Derek's attention more than Mark's, and he stood up. Mark, slowly, followed suit.

"How can you be okay with this, Mer?" Mark asked, astounded. "He got in your bed! At night! He slept with you!" He went at Derek again and I jumped between them.

"It…It wasn't his fault! We were talking…and we fell asleep." It hurt to lie to Mark, but I didn't want Derek to get hurt. Derek had muscle…but not as much as Mark.

"Oh bull shit!" Mark growled. Fail. "He had his arms wrapped around you! And his face…his face in your…neck!" As he said it he glanced at my neck, looking sick when he saw the small bruise I tried to hide.

"Oh hell no! I swear to God if that's a…" he gulped, unable to say the word and I looked away, ashamed of hurting my brother.

Derek readied himself for another fight and clenched his fists.

Mark, however did not plan on fighting, and slumped over, defeated.

"We're brothers, Shep…"

"I know."

"She should be like your sister!"

"She's not." Derek said with an air of defiance, and pulled me to him, my back against his chest. I couldn't help but be proud when Derek stared straight at Mark, refusing to look away or let go of me.

Mark looked angry, again, when he eyed Derek's arm wrapped protectively around my waist. If he wanted to hit Derek again, he didn't show it.

"Talk," he sighed, "we can talk about…whatever this is…with you two." He walked out of my bedroom and headed down the hall.

Derek and I both let out a loud whoosh of air and he let his head fall to rest on my own. He pressed several kisses to the top of my head before letting go of me and spinning me around to face him.

"This will work out, Meredith. We won't have to hide anything anymore and it'll be good." He didn't seem positive about it though. Even though Mark had agreed to talk with us, it didn't mean he couldn't say he didn't want us together.

I voiced my fears, "But what if he says he doesn't want us together?"

"Then we're back to hiding things. I won't leave you, Mer. I won't, not even for Mark."

I nodded and kissed his cheek before following him out of my room.

D POV

Mark stared down at the kitchen table, drumming his fingers quietly. I cleared my throat as I walked in with Meredith trailing a few feet behind me. We sat beside one another, pushing our seats closer together.

As Mark looked up at us, looking hurt and confused, I trailed my hand down to Meredith's knee and squeezed it in reassurance.

"Hands on the table, guys. I don't want to even picture that lovey dovey shit."

I glared at him before, reluctantly, bringing my hands up on the edge of the table.

"I don't like this. At all." Mark started.

"But we-" I interrupted.

"Shut up, Shep. Let me freaking talk!" I clenched my fingers around the edge of the table, but let him continue.

"One of you will hurt the other, and I'll be in the middle of it. I don't like it…but I don't think I can stop you if this is something you all are going to be serious about."

I bit my bottom lip to keep from grinning and I'm sure Meredith did the same.

When it seemed like Mark was finished, I leaned down and kissed Meredith gently.

"Agh! None of that crap around me. I said I don't like it." He got up quickly to leave and I laughed when Meredith blushed.

"Oh, and Shep?" He turned around in the doorframe. "If I hear anything…wrong…about my little sister come out of your mouth…I really will castrate you."

I instinctively brought my hand down to cover my jewels and gulped.

Mark smirked again before he walked down the stairs to turn on his X BOX and play.

"Should I go with him?" I asked Mer.

"If you want to…" she trailed off, looking uncomfortable.

"Can you believe it?" I sat back and looked to the ceiling.

"There is a God and apparently he likes you," she giggled.

"C'mon, woman. Let's go celebrate." I wriggled my eyebrows suggestively and she laughed again.

Even though Meredith and I hadn't done those types of…things…yet...didn't mean we didn't constantly imply it. I bent in to nip her neck again, and pulled her up out of her chair.

"Now, Derek. I think you really should go talk to Mark for a few minutes. What will he think if you start ditching him for the little sister?"

"You're right," I grumbled, before leaning in and capturing her lips in a kiss.

I slowly made my way down the stairs, with several backwards glances to Meredith for encouragement.

M POV

I went down the hall to my room once I heard the sounds of violent video games make their way from Mark's room. Guys.

I walked over to my iPod and pressed play, the music blaring through my stereo. I sang along and picked up my room for a while, opting to stay in my pajamas for a while longer.

After my room was spotless, I went to the bathroom to get rid of my morning breath, take a shower, and brush my hair out. I looked like Hell and winced when I realized that this was what Derek had awoken to. Yep, definitely time for the shower.

I walked out of the bathroom feeling refreshed and clean and went to my room in search of jeans and a t-shirt.

I slipped on my indigo bra and smiled at the memory of Derek saying how much he liked it. After pulling on some matching boyshorts I turned around to find an open-mouthed Derek standing in my doorway.

Leave me love!!! I hope you all liked that one. I know this story is almost all DPOV lately, but I feel like the more recent stuff is better told from his perspective.
