Author's Note: Since I got some good reviews for my last chapter I'm continuing my story.

Sorry that it took so long. Got in a fight with my little brother and got grounded.

Chapter 2: Erica Hahn

Up at peds Arizona was at the nurses' station filling out some charts when a blonde woman walked up next to her. "It's pouring outside, I forgot how much it rains in Seattle." the blonde told Arizona.

"Yeah but you get used to it." Arizona said as she turned towards the blonde and offered her a smile. The blonde smiled back and was taken aback by how beautiful Arizona was.

Before she could stop herself the blonde said, "You have the most amazing dimples." When she realized what she just said she looked away but not before she saw the peds doctor look down and blush.

"Thank you." Arizona said, "I'm Arizona Robbins head of peds." Arizona offered the blonde her hand.

She shook her hand and managed to say, "I'm Er-" before they were interrupted.

"What do you think you're doing?"

"Sloan. I would say it's nice to see you again but I was taught not to lie." Erica told Mark.

Meanwhile Arizona looked at them confused. Mark took out his phone and sent a text.

"Sloan we're talking here. You know, two adults having a conversation, but of course you wouldn't know because all you're good for is sex."

"Actually I'm in a relationship believe it or not and it's not all about sex we talk." Mark defended himself.

"Who's the unlucky girl?"

"None of your business." Mark said getting angrier.

"Well what's wrong with her because obviously something is if she's dating you?" Erica said taunting Mark. She always enjoyed getting Mark mad.

"That's it," Mark said having had enough, "I'm going to-"

Just then Erica's pager went off. "Sorry Sloan we can finish this conversation when I come back." Erica left and Mark and Arizona are left in an awkward silence.

"Were you just flirting with her?" Mark asked Arizona.

"Of course I wasn't. I admit she was flirting with me but I would never flirt, with anyone."

"Do you know who that is?"

"You interrupted her from telling me who she is. So who is she? You two obviously know each other."

"That's Er-"

"I'm back Sloan so what were you going to do to me?" Arizona can't help but laugh at Mark whose face turned red with anger.

"So…" Erica said as she turned towards Arizona, "You want to go to Joe's after our shifts are done so I can formally introduce myself."

But before Arizona could answer Mark said, "I've had enough of y-"

"Mark I got your text." Callie said turning the corner while looking down at a chart. "Thank god you fou-" She skidded to a stop as she finally looked up and saw who was with them.

"Hi." Callie said stealing a sideways glance toward Arizona.

"Uhm hi." Erica replied.

"You know each other?" Arizona asked Callie. Callie realized Arizona didn't know who this was and was relieved that she was there to tell her. "Uh, yeah. This is Erica Hahn." Callie told Arizona looking at her closely to see how she reacts.

Realization dawned on Arizona's face. "Erica? You mean the Erica."

Callie just nodded. They stood there in silence until Lexie walked up.

"There you are Mark I've been looking all over for you." She said giving Mark a quick kiss on the lips. "I just wanted to tell you that I'm going to get home late. Owen is letting me scrub in into one of his surgeries…" Lexie trailed off finally noticing the awkward silence. She noticed the blonde doctor. "Dr. Hahn I didn't know you were back at Seattle."

"Just for a few weeks." Erica didn't know what this girl's name was. She had only caught glimpses of her when she used to work here but obviously she knew who she was. No doubt Mark would have told her everything.

Lexie realized that they were never introduced so she said, "I'm sorry I've heard so much about you it's like I know you."

"I'm sure you have heard a lot about me." Erica said looking at Mark.

"I'm Lexie Grey."

"Grey?"

"Yes I'm Meredith's younger half-sister." Mark cleared his throat and Lexie took it as her cue to leave. "Well I'll see you later Mark. Dr. Hahn it was nice to meet you. Bye."

Erica nodded her head and Lexie left.

AN: I decided to post one chapter every week until the story is finished, (I don't know how much longer I'm going to make it) most likely I'm going to post them on Tuesday's. So check back every week for the next chapter. Please review.
