"Hey Dad. I thought you were in surgery."

"I paged Jackson to finish up so I could greet you. What does Derek want to check?"

"It's nothing, really."

"Brooke!" Derek interjected.

"Okay, so maybe it's something. I'm fine now. Really. Peachy. It's just there was this thing, at my school, yeah? And I was sort of shot, and my stitches need checking."

"You were shot?" Brooke nodded, but thought it was best to remain silent. "Did your mother think it not pragmatic to call me? As your dad and your surgeon?"

Brooke shrugged and held her hands up. "Talk to Victoria. I was unconscious and bleeding."

Mark shook his head, amused at his daughters antics. "Lay down. I think Derek wants a look at these stitches as much as I do." Mark was struggling to stay in control. He was so excited to see his daughter, but she came to Seattle with a gunshot wound. Seriously? A gun shot? How the hell did that happen in Nowheresville, North Carolina?

"You should have called me, Brooke! These look months old!"

"It was six weeks ago, jeez! I'm sorry calling you wasn't on the top of my list!" Brooke stormed out, pulling her shirt to cover he wound.

Mark sighed, but left the room. He needed to give his oldest daughter space, but he needed to make sure that she was alright. But he couldn't do that at the moment, so he settled to go seek comfort from baby Sophia.

Brooke got outside, and sighed. It wasn't Mark's fault. He had every right to be upset, and he wasn't upset at her. She walked back in and saw her uncle.

"Uncle Derek!" Derek looked relieved. "Do you know where dad went?"

"He headed to the nursery to check in on Sophia."

"Who's Sophia?" Brooke frowned, getting a bad feeling.

"He didn't tell you." Brooke shook her head. "Brooke maybe you should sit, I'll call your dad and-" but Brooke was already running to the nursery. Derek sighed. This wasn't going to end well.

Brooke found out where the nursery was because she needed to find out why his dad had to visit "Sophia" there. Brooke knew there was only one plausible answer as to why he was there, but she didn't want to admit that her dad didn't want her, but he wanted somebody else.

Brooke peered around the doorway, and there, he saw her dad with a baby. Who had his eyes. Brooke's eyes. She backed up.

"Are you alright, sweetie."

Brooke fervently nodded her head. "Yeah, yeah. I'm fine. I was just looking for my dad. I found him. Thanks. Bye."

"Wait, who's your dad, sweetie?"

"Mark Sloan." Brooke sighed and walked away.

The nursery supervisor walked into the nursery. "Hello, Dr. Sloan. How are you and Sophia doing?"

"I'm fine Nancy. Everything's fine?"

"Yeah. I just met your other daughter outside. She seemed nice. Will she be staying long? I have to say it will be great for the two sisters to get to know each other, and Sophia's mothers."

Mark smiled. "Wait, Brooke, she was here?" With Nancy's nod, Mark's smile faded. "Thanks Nancy, I have to get back to work. See you soon, Sophia." He kissed his daughter and handed her over, then left."

"Derek!" Brooke called. "He has a daughter? Seriously?" Derek nodded. "I changed my mind, I don't want to be here. But I can't go home...can I stay with you."

Derek looked shocked. "Brooke, I think Mark was really looking forward to spending time with you. Give him a chance to explain."

"No. He has a shiny, unshot, undamaged daughter who won't be a slutty cheerleader when she grows up because she has moms who love her and a dad who wants to be around. He doesn't need me. I'm a failed experiment, Derek!" She started crying and Derek pulled her into a hug. "We'll figure something out, Brookie, we'll figure something out."

"Brooke!" Mark called. "Please, let me explain!"

Brooke pulled herself from Derek's arms. "No. I'm done. DONE!" Brooke stormed off.

"Derek, what am I going to do?" Mark looked lost.

"Maybe she can stay with Meredith and I for a few nights. You can see her during the day, set up a room for her, and then she can stay with you?"

"Fine." Mark said, clearly unhappy with the compromise.

Brooke ran. And ran. She saw a bar across the street. Just what she needed. Her phone rang and she recognized Lucas' number on the Caller ID; she ignored the call. Brooke entered the bar, flashing her fake ID, ordered two shots and downed them upon their arrival. She ordered a beer and began to nurse it.

A while later (three beers later), it was late, and the bar was beginning to fill up. Brooke was more than buzzed when someone slid the beer from her. She looked up to see Dr-Alex.

"Hey."

Behind him was a blonde woman, Brooke assumed another surgeon, maybe Alex's girlfriend.

"Brooke, what the hell? Mark's been looking for you everywhere."

Brooke shrugged, but the blonde woman exclaimed "Holy Crap! You're little Sloan. Well medium Sloan, really, because there's Mark and Sophia and Sloan Riley-Sloan. Lots of Sloan spawn."

"Hold up...there's more than just me and Sophia?"

Arizona gulped. "You should talk to your dad about Sloan Riley. She's a confusing situation."

After that, they insisted that Brooke come with them, but Brooke insisted to be taken to Derek's, not Mark's.

Mark was sitting on his couch, at his apartment when Arizona burst in. "What do you think you're doing here? Go to your daughter. Imagine coming to saty with your dad as an only child, only to find out that you have two sisters you never knew existed!"

Mark got up. "Can I take Sophia to see her? I know it's your night with her, but I'd like them to bond..."

"Of course. Callie's making dinner. Bring some over with you."

So, Mark found himself knocking at Derek's door an hour later, Sophia in one arm, dinner in the other.

Alex answered the door, with one a look, he left, though he left the door open for Mark.

"What's going on?" He asked when he only saw April and Jackson in the living room.

"Brooke came home with Derek. Mer had Zola and when Brooke saw her she blew up. Talking about how everything changed and no one wanted her-you, Derek, Lucas (whomever that is) because they all have shiny new toys." Jackson said while looking at Mark.

Mark climbed the stairs, stopping to put Sophia with Zola in a playpen, and then proceeded to look for Brooke's room, which wasn't hard, as Derek had taken up residence sitting next to her door.

"Brooke, let us explain." Derek called, exasperated.

"What's there to explain, Derek? You both had babies and forgot to tell me!" Brooke yelled through the door, and mumbled some more.

"Come on Brooke! You need dinner!" Derek called. "Mark is bringing some over!"

"Chicken." Mark supplied.

Brooke slammed the door open. "Who the hell do you two think you are? While I'm dealing with car crashes, relationship drama, and shootings, I still managed to call you? You couldn't find it in your schedules to drop a hint that you had kids?" The men looked guilty. "And who the hell is Sloan?"

Mark sighed. "She's your older sister. I never knew her!" He hastily added. "She found me...she was pregnant, and I was going to take her baby, but she decided to keep him. I'll try to get them to come visit and meet you."

"Don't bother. You were going to adopt some kid without...I don't...telling me?" She grabbed the bag of food from Mark and stomped down the stairs.

Brooke entered the kitched, seeing Derek's wife, she held up the bag. "Want some dinner?"

Meredith smiled. "Thanks. I hope Callie made it. She's a better cook than Mark is on her worst day."

"Who's Callie?"

"She's...your dad's best friend, besides Derek, that is...and she's Sophia's...mother."

"And they're not together?"

"She has a wonderful wife, Arizona."

Brooke shrugged. "Cool."

"You know, I can relate to you, quite well, actually." Meredith commented while grabbing plates from the cupboard. At this point, Mark was held back from entering by Derek, gesturing for him to give the two women a moment. Brooke looked up questionably. "My mother left my father when I was young, and took me. I found him during my internship and showed up at his doorstep. I didn't want any relationship. I found out I had two sisters when my younger, pregnant sister showed up and I was on her case at the hospital." Meredith laughed. "You'd probably appreciate the irony that my attending was Addison."

Brooke snorted. "Isn't it always?...I'm sorry about your dad."

"Lexie is my other sister. The other Dr. Grey."

"Wow...that's...messy." Brooke and Meredith laughed.

The men, sensing the tension dissipating, entered.

"Come on Brooke. Don't you want to meet your cousin?" Derek asked.

Brooke sighed dramatically. "Fine. Lead me to the dratted child!"

Derek, Mark, and Brooke left Meredith to set the table for the house.

Brooke walked in and sat on her uncle's bed as each man took a baby.

"She's too cute, Derek! Hello, Zola! I'm Brooke, and I'm going to teach you how to dress to get all the boys!" Derek groaned.

"That's it, Zola! You're never allowed alone with Brooke, ever!" He said jokingly.

Mark laughed, and both men sat down, sandwiching Brooke between the two of them.

"Sophia, this is your sister. Brooke, this is Sophia." Brooke nodded, but fiddled with her bracelets. "Want to hold her?"

Brooke shut up from the bed. "I should go help Meredith. It wasn't fair to leave her alone to clean."

She walked out of the room. Derek felt terrible for Mark and Brooke, alike. It was a horrible situation, but it would solve itself it time. Brooke could never stay mad for too long, and how much could change with Brooke's temperament?
