Hey Guys! I deleted Passion Taste Better because I didn't like the direction it was going in and it wasn't getting that many responses. So I revised it and made it to a different story. Hope you like!

Summary: Meredith is Mark's little sister. Mark and Derek are residents and Meredith is an intern. They all live together in a house near the hospital. Izzie is childhood friend of Meredith.

Mark Sloan sat in the kitchen wondering how he got to this point in his life. He and Derek had planned their lives from when they were little. Graduate high school, go to the same college, finish medical school at the top of their class, and then after all the necessary step to climbing the hospital ladder finally build their own practice. And so far everything was going as planned, but what wasn't planned was the unexpected showing of Mark's younger sister, Meredith.

Mark remembered that day like it was yesterday, the day he finally had his sister back.

It was the beginning of Derek and Mark's senior year and her freshman year.Derek was at the library studying claiming that he could never study near Mark when he was watching a game, that all he did was yell. It was raining so Mark was in his reclining chair watching back to back basketball games. He was mid scream when he heard a knock on the door.

Grumpily he got up checked his personal calendar to check if he had a date for tonight. 'Nope, one of the few days empty' he thought as he walked to the door. He opened the door not prepared for the figure on the other side.

Meredith.

He did nothing to cover the shock that graced his face. He and Derek hadn't seen her since she was 14. When she was younger they were close especially with the absentee people they called parents. They used to pull pranks all over the house, each taking turns of who would take the blame. They never really yelled at Mark and he never knew if it was because they just cared less or because he was boy. But they yelled at Meredith, saying it was unbecoming of a woman. Soon she was sent to boarding school and they drifted further and further apart. He thought that maybe she blamed him for her getting sent to boarding school. That maybe if she hadn't listened to him and his plans she wouldn't have been shipped off. They hardly talked when she was away and when she did come home for vacations because he was usually at Derek's.

"Hey Stranger" she said soaked to the bone with bags in her hands. "You going to let me in"

Mark just nodded his head and moved out the way. When she noticed he didn't say anything she dropped her bag and let out the deep breath she was holding.

"Can you say something?"

"What do you want me to say? I haven't seen you in four years. You hardly talked to me when you came home from sch--"

"They said they would cut me off" she explained

"What?"

"They said that if I got in trouble anymore they would cut me off. That I had to start acting like a young lady and they thought it would be best if I were away from you. I was young…and I was scared" she said tearing up. "And I'm sorry"

He grabbed her by her arm and pulled her in for a hug. He always hated to see her cry. "So what made them change their mind" he asked quietly.

"They didn't. This college has one of the best medical programs in the country" she smiled sheepishly. "They couldn't exactly say no when I applied"

"Always looking for a loophole, aren't you Mer" he laughed.

"So can I stay?"

"Well you left me with no choice. I can't exactly kick you in a street with the rain and everything"

She scoffed as she punched him in the arm "You're still a jerk"

"I missed you too"

Mark was broken out of his trance by the sound of her voice.

"Hey Mark, guess what." Meredith screamed after getting off the phone.

"What?" Mark asked amused at his sister's excitement.

"Izzie's coming to intern at Seattle Grace" she smiled happily

"Who the hell is Izzie?"

"Come on, Mark remember she went to boarding school with me and her parents house was down the block from ours. She used to sleep over the house all the time"

"Oh yeah the little chubby one who was always in our fridge sure I remember" he said with smirk.

Meredith playfully smacked him in his arm. "Stop it she's going to start at the hospital soon, isn't that great. I mean we never lost touch so it's not like we have to catch up on anything we can just pick up where things left off."

"Well isn't that great for you and the supermarket if she still has the same appetite she had back then" laughing at the glare he was receiving from his sister.

"Stop being such a jerk"

"Aw but that's what makes me, me"

"Whatever, well she's coming over today. I might have to go pick her up from the airport around five but when she gets here. Be. Nice." She warned narrowing her eyes at him.

"Scout's honor" his eyes gleaming mischievously.

"I'm serious Mark, now what's for breakfast"

As they were eating breakfast the doorbell rang and Meredith ran to the door "Derek, where is your key? I thought you were supposed to be the responsible one" she said walking away from the door

"Cute, very cute" he said sarcastically as he entered the house

"I know. I try" she continued to walk away with a smirk.

"You know she acts more like you everyday. I think your rubbing off on her." Derek stated as he and Mark sat on the couch

"I know isn't it great!"

"She's the same with guys as you are with women" laughing as Mark's smile feel from his face.

"Not possible I have a GPS on that girl, I'm like the damn CIA with those guys. They know if they sit too close they can hear a gun shot in the distance"

Derek laughed at Mark's serious face.

"She's twenty-six years old. You can't monitor every guy she dates."

"And why not men today are dogs"

"Namely the ones that act like you"

"Exactly so who would know better than me"

"So, what am I your partner in crime?"

"Yes, as my best friend your Agent #2"

"Agent #2, how come I'm number 2 why can't you be 2.

"A second ago you were laughing at me and now you want to be numero uno, I don't think so Sheppard"

"Your sister is as indecisive as you anyway. She doesn't like commitment either"

"I know that. And a part of me is happy about that but another doesn't want her growing up alone with just her brother by her side, you know" he finished as he heard the door bell.

The bell rang three more times before Mark got to the door. "Hold on a sec" he said then stubbed his toe against the chair "God Damn it, Derek go get that" he screamed hopping on one foot to grab the other.

"Sure because that's what I do right, listen to Agent #1" Derek asked jokingly.

"Derek just shut up and get the door"

Just as Derek was getting to the door they heard Meredith up stairs. "Hey was that the door"

"Kind of late there don't you think" he said sarcastically

"Shut up" she replied. Derek opened the door and Mark instantly stopped hopping and stared at the girl in front of them. His gaze skimmed her from the bottom up with legs that looked like they never end in her tight jeans and pumps and her long blond hair that was skimming her shoulder blades.

"You must be looking for me" Mark said as he stepped in front of Derek. "May I ask who you ar--"

"Izzie!" Meredith screamed she ran down the stairs as fast as she could to give her a hug.

Izzie!! That is NOT the bulldozer I remember.

"Hey Meredith. I missed you." Izzie said as she squeezed her friend back.

"Oh my god you look so different" Meredith gasped

"Is that a nice way of saying wow you don't look fat" she laughed as Meredith tried to cover her tracks. "I was joking, this is what sports and Yoga does to a girl. Especially a girl who had a lot of stress in her life and needed a way to burn it off"

Then she looked up at Mark and smiled "Sloan" then looked him up and down. "Mom did used to say men look better with age but I didn't think that jerks were included in that" she smirked up at him.

"I'm not sure how I should take that" Mark frowned.

"Trust me it was a compliment"

"Not the age part" he said not noticing that she called him a jerk after he heard the word age.

"Aw that's okay the gray hairs are really going to bring out your blue eyes" she smiled trying not to laugh at his reaction.

I'm thirty, I do not have grey hair" automatically reaching to touch his hair.

"Izzie stop trying to flirt with Mark" she said as she pushed Izzie towards the stairs before turning back. "Pretty hot for a chubby kid huh Mark." She smirked knowingly at how Mark was staring at Izzie when she came to the door.

"Her friend is going to be an intern. Hmm she didn't peg me as a person who would be in the medical field?" Derek asked as he watched them go up stairs.

"Why because she was blond, had legs for miles, and looked like a man-eater."

"Don't even think about it Mark"

"What?"

"You play another one of Meredith's friends and Meredith said she would cut off your manhood" Derek said laughing.

"Now why would I do that?"

"Because it makes you feel like a man" Derek smirked.

"I'm under control alright" Mark replied as his thoughts were still on those pairs of pumps and the legs that never ended.
