(A/N) I changed the story around so chapter one is new and improved 

"All right interns gather around. We have a new intern, some of you might know her some of you may not, but that doesn't matter. I need you to show her the ropes around here; she's just out of med school and moved here from Boston. Ok? I got a 911 I got to go, this is Melanie Grey." Bailey stated to all the old interns. Bailey runs off and leaves a young girl who looks very nervous.

"Hey doesn't she look like someone to y-" Christina started to tell Izzie but was interrupted by Meredith.

"Oh my gosh! Melanie?! I haven't seen you in like…"

"Five years…yeah it's been a long time."

"hhhem, ummm… yeah still not getting the connection of how you two know each other." Christina said.

"Oh! Sorry, everyone this is my little sister Melanie. Melanie these are the other interns. This is Christina, Izzie, George, and Karev or Alex whatever you want to call him.

"Nice to meet you all." Melanie says politely

"And nice to meet you too maybe we could hook up sometime you know just-" Karev started

"Yeah I don't see it happening," Melanie said cutting him off.

BEEP BEEP

"Oh, sorry that's me I got to go!" Izzie explained

"Oh man me too, sorry" George apologized as he ran off.

"Karev don't you have somewhere to be like with the she-Shepard or something down at the gynecology unit?" Christina asked.

"Bite me."

"Well, I'll just leave you two to catch up since you are the ONLY ones on break!" Christina said as she strolled off to do some lab work.

"So those are the people I'm going to be spending the next six years of my life with? Wow, they're interesting." Melanie said looking around.

"Yeah, they're pretty awesome, hey I'm pretty hungry and since there is too much to talk about then we cant sleep so lets eat," Meredith says as she walks down to the cafeteria.

When they finally sit down with their food, Meredith starts asking questions.

"So, how's Maddie?"

"You remember Madison?! Wow!"

"Ha Ha," Meredith's voice with sarcasm, "of course I remember my baby sister, well she's probably not so much a little girl anymore. Gosh, I've missed you guys so much, so tell me what's going on with her."

"Well since mom is, well where she is, I've been taking care of her. She's fifteen, almost sixteen as she keeps reminding me, in high school and will be going into college then med school to become a surgeon, big surprise, huh?"

"15, wow time really has gone by."

"Yeah, but she's coming by in a little while, and she can't wait to see you again."

"I can't wait either! So where are ya'll staying?" Meredith asks while stabbing her salad with her fork.

"We just got an apartment near here, and we're just waiting to move in."

"Well…..you could stay with me."

"What?"

"Yeah, I'm in Mom's house. It's just me, Izzie, and George."

"Just you, Izzie, and George? Mer that's three people! Four of which are doctors and Madison is fifteen she's a teenager, and sometimes hard to handle."

"No! we have room. It's a five bedroom house remember? Come on, please? I haven't seen you in forever and I need to make up for lost time."

"I don't know Meredith; I mean I'm taking care of Maddie…"

"She's 15! And I want to help you I mean I am the oldest I guess I should start acting that way, I wasn't fair to you to do it all by yourself, now I want to help."

"But Meredith, she's fifteen even though she's like a genius and some people expect her to be so mature, she's still a 15 year old who will experience with all kinds of teenage stuff. Don't you remember being a teenager?"

"I don't care; I want to be there to help."

"You don't take no for an answer do you? Ok, I guess we could move in," Melanie says after much dismay.

"Great!" Meredith squeals and gets up to hug her younger sister.

"Mel?" Mel turns around and sees he baby of the family.

"Oh, hey Maddie, I didn't know you'd be here so soon."

"Hey Maddie," Meredith whispers as she pulls her into a hug.

"Oh my gosh, I've missed you so much," Maddie cries.

"Same here kiddo."

They stay like that for a minute before Melanie breaks the silence.

"Hey Madison guess what? Instead of living in that crappy apartment we're going to move in with Meredith."

"Seriously? All right!" Maddie squeals with delight.

BEEP BEEP

"Hey Maddie we'll be back in a little while, get something to eat and hang out wherever. Come on Mel; follow me it's a 911." Meredith says as she sprints off down the hallway with Melanie close behind.
