"The new Shepherd is awesome" Alex laughed as he sat down on the gurney between Meredith and Lexie and took a bite of his apple. Avery took the wheelchair opposite and joined in the praises of the new Attending whilst starting his lunch.

"Wait, who is the new Shepherd? Derek's been replaced?" April asked anxiously. She could bear to think Derek had left Seattle Grace not without saying anything. He was her 'mentor' or at least that's what she told everyone.

"No Derek is still here, his sister Lauren is the new Paeds Attending" Meredith corrected and nudged Alex as he stole one of her fries.

"Dr Robbins hasn't even been gone three days, how did she know about the job?" Lexie wondered curiously.

"Apparently she worked with Robbins at Johns Hopkins so Shepherd was the first person she called when the Carter Madison grant came up" Alex answered mid bite. He and Avery had already asked Lauren that question in between patients on rounds that morning.

"How did Robbins not put two and two together when she started working here with Derek?"

"Oh she knew he was her brother, she just didn't make a big deal about knowing one of his sisters" Avery answered this time

"How do you two know all this?"

"We kind of badgered Lauren with a heap of questions because Bailey didn't join us on rounds. We didn't get the chance to ask her in surgery with Bailey there" he laughed

"You guys call her Lauren?"

"Not to her face" Alex laughed and stole another one of Meredith's fries "She wants to meet you though. She keeps calling you the post-it wife"

"Oh great" Meredith sighed lightly. Meredith didn't exactly have the smoothest run with Derek's sister. She thought he was cheating on her when she saw Nancy in the trailer and she gave Amelia the benefit of the doubt when Derek couldn't. There was no avoiding this sister though; Meredith was on Paeds rotation the next day.

"Twenty bucks says she hates Meredith right off the bat" Avery laughed before having to avoid a handful of flying fries being pelted at his head

"You're probably right though" Meredith sighed lightly. Without a doubt she would do something stupid and Lauren would end up hating her. That'd probably be easier for Derek having an Allie rather than an enemy. "I guess I should go find the She-Shepherd and introduce myself"

"The She-Shepherd? Isn't that what we used to call Addison when she first got here?" Alex laughed

"What would you rather we call her then?"

"Well McDreamy is her brother and McSteamy is his best friend so how about..." Lexie thought with a chuckle

"McYummy" Avery piped up with a smirk. Alex quickly agreed much to the arguments of the girls "What? She's kinda hot"

"Think of something else" Meredith sighed as she stood up "before you spread McYummy through the hospital"

"Yeah don't count on it"

XXXXX

"You can't tell me that you're here without Mom even knowing" Derek sighed as he walked with Lauren down the hall of the surgical floor. He couldn't understand why of all places, Lauren had to be in Seattle if their mother didn't know about it.

"I don't even know where she thinks I am. I haven't spoken to her, Nancy or Kathleen in five years" she insisted. Lauren just couldn't get it through to her brother that she had cut their family out just like he did.

"But you've spoken to Amy?"

"I passed through LA on my way here. I saw Addison too, she cut her hair"

"Not the point Lauren" he growled lightly and picked up his patient's chart as they got to the nurses' station. Reading through it, he familiarised himself with the case hoping it would get him away from his sister. "I don't believe that you just cut Mom out and didn't tell her you were in London"

"Well I was in Greece for a few weeks before London but that was strictly holiday and a lot of cocktails on the beach" Lauren laughed but her joke didn't even warrant a smile out of Derek. "I left about a week before you walked away from all your problems in New York. Last week wasn't the first time I'd spoken to Amelia in 5 years Derek" she snapped knowing that hit a heartstring.

"I didn't walk away from my problems. They drove me away from New York"

"That's a load of garbage and you know it. Addie cheated and you ran away"

"Tell me again how we got onto this topic again?" he sighed and crossed his arms

"We got onto this because you're in a constant state of denial. Did you ever think that I came here as a favour to my old friend Arizona, and that you or your obsession with thinking Mom is always checking up on you, were never a factor in my decision?"

"I am not..."

"As much as you don't want me here Derek, I'm not going anywhere" Lauren insisted "I like Seattle, it doesn't rain quite as much as it does in London and I like this hospital. I needed a fresh start and Arizona gave it to me so I'm sorry for invading your precious territory but like it or not I'm staying" she snapped and turned away from her brother only to slam straight into a petite figure. Collecting herself, Lauren watched her brother drift toward the figure and pull her close to his side. "You must be the post-it wife"

"Lauren..." Derek warned

"Meredith Grey. Nice to meet you" Meredith smiled and extended her hand out to Lauren.

"Lauren Shepherd, nice to put a name to the... no I haven't heard a thing about you actually. Derek isn't all that talkative"

"Yeah I know what you mean, I knew you existed but I didn't even know your name"

"That makes me feel all warm and fuzzy Derek, thank you" Lauren chuckled and glared playfully at her brother. He stood back against the nurses' station clearly uncomfortable at the bonding between his wife and sister. "He never has been one to talk about his many annoying sisters"

"I can't relate, I'm an only child" Meredith chuckled looking back at Derek with a 'she seems nice' look on her face.

"Sounds like heaven to me"

"Really Lauren?" Derek sighed softly

"Oh come on. You still wish for four less sisters"

"Or just a brother..."

"Not gonna happen" Lauren laughed "But you might be getting another nephew. Nancy is pregnant again. 22 weeks along I think"

"I thought you said you hadn't spoken to Nancy"

"I haven't, Amelia told me" she chuckled and took the chart from the impatient nurse that had been waiting by her side for the last ten seconds. "It was really nice meeting you Meredith but I have to see this patient. We should catch up for a drink tonight"

"Sounds good" Meredith smiled and ignored Derek squeezing her hand behind her back as they watched Lauren walk toward the elevator. Turning back to Derek, Meredith pulled her hand from his grasp "Ow"

"You're having a drink with my sister?"

"She seems nice and I'm on her service as of tomorrow so I have to like her" she chuckled and leant up kissing him quickly "What harm could one drink do? Embrace that she's here, frown lines aren't handsome on you"

"You're all bright and shiny about my sister... I don't like it"

"Enjoy your sister's presence"

"Yes Confucius" he mocked warranting him a light slap on the arm from his wife "Why do you want me to like having her here?"

"Because she's family. I grew to like Lexie and now you can grow to like Lauren. Deal with the bright and shiny" she smiled and kissed him one last time before skipping off to check up on her post-op patients.

Thoughts?
Will Derek embrace and enjoy the presence of his little sister? :P
