AN: I decided to take down the original chapter and repost it. After reading some reviews and reading it over myself I really wasn't happy with it.

Chapter Three—From now on

"Wait… what?" Derek furrowed his eyebrows, putting the iPad with Amelia's chart off to the side. "Addison Montgomery, as in…" He cut his sentence off, and Amelia responded simply with a nod. He stood up from the bed, motioning for her to do the same. "Come with me." He started walking down the exit of the ER, with Amelia following behind. They approached a door, with a sign next to it that read 'Chief of Surgery.' Amelia raised an eyebrow and walked inside behind her father.

"You're the chief of surgery?" Amelia asked, and Derek nodded as he pulled out his desk chair and sat down. Amelia was impressed, but curious why Reese didn't mention that. "How long have you been the chief?" She asked, genuinely curious about her father's career. He seemed like such an interesting person; someone she could truly connect with.

"Only a few weeks," He responded, opening a desk drawer and pulling his phone out.

"Wait," Amelia approached his desk, feeling a sudden panic rise up in her chest. "Wait, what are you doing?"

"I'm calling Addison," He replied, as if it were obvious. "I'd like to hear it from her."

"What, you don't believe me?" Amelia speculated, crossing her arms stubbornly over her chest. "Why would I make something like that up?"

"Oh, I don't know; maybe because I'm one of the highest paid surgeons in Seattle? You aren't the first person who has popped up out of the woodwork pretending to be a long lost relative."

"Oh, don't flatter yourself," Amelia was honestly surprised at how brave she felt. She wasn't a particularly confrontational person, but this wasn't the reaction she was expecting from Derek. She thought he'd be happy. "I don't care about your money. I wanted to meet you. I wanted to get to know you. Apparently, that was a mistake. Have a nice life, Dr. Shepherd." She headed toward the door, hoping and praying her bags were somewhere safe. If they weren't, she wouldn't have money for a hotel room.

"Wait," He called, stopping her in her tracks. She stubbornly fought the tears that were burning the brims of her eyes and turned around. "I just… I need to hear it from Addison."

"This is a hospital. Just do a DNA test." Amelia rolled her eyes, crossing her arms again. "Look, if you call my mom she'll make me leave. All this trouble will have been for nothing."

"I understand that, Amelia… but she's probably worried sick about you." Derek's demeanor changed slightly, but Amelia could tell he was still guarded. He stood up from his desk and crossed the room, standing in front of her. "We can do the DNA test. If you are my daughter, like you say you are, then you have to promise me you'll call your mother by the end of the day."

Waiting for the DNA test results were torture for Amelia. She knew Derek was her father; it was obvious. She was the spitting image of him. However, there was always the slight chance she wasn't his child, and that thought terrified her. She was extremely grateful that the hospital offered same day processing for the test results. As they waited, they sat in Derek's office. His desk was full of paperwork, and his phone was constantly ringing. She could Derek's job wasn't an easy one.

Derek asked the receptionist to have someone bring Amelia's bags to his office. She unzipped her carry-on bag, pulling her phone out. She turned it off after she ordered her Uber, as her mother was constantly calling. She felt terrible, imagining the torture her mother must have been going through. She held down the power button, and once it was fully powered on, she double checked to make sure her location services were turned off. Almost immediately, a phone call from Addison came though. She inhaled sharply, causing Derek to look up from his paperwork.

"Aren't you going to answer that?" Derek asked.

"N-no," She answered, hitting the reject button. There was alarming amount of missed calls, voicemails, and text messages. Most from Addison, some from Mark, and a few texts from Reese asking how her trip was and if she had found Derek. She sighed, turning her phone back off and putting it in her bag.

"Addison's probably worried about you," Derek commented, looking back down at his papers.

"I'm sure she is," Amelia replied, scoffing as if it were obvious. "She always is."

"She's overprotective?" Derek looked up again, seeming genuinely interested. Amelia felt warmth well up inside her. She'd never had a father figure; Mark was always around, but he wasn't very fatherly.

"That's an understatement," Amelia laughed. "She's a bit… much, at times."

There was a knock on the door. Both of them turned their attention to the door, which slowly opened. "Oh," the woman who opened the door spoke. "I'm sorry, Derek. I didn't realize you were meeting with someone. I just picked you up a coffee."

Derek sighed, putting his pen down and pushing his paperwork off to the side. "It's fine, Meredith. Come in… there's something we need to talk about."

"So, let me get this straight. You were married for twelve years, and you hid that from me?!" Meredith was pacing Derek's office with her hands on her hips. "We're married, Derek! We have children, and you hid this from me?!"

Amelia say awkwardly in the corner of Derek's office, with her head in her hands. She felt horrible. She felt like everything was falling apart. This wasn't what she was expecting at all. She wanted nothing more than to leave. She would rather face Addison than sit in this room any longer. Any time she'd try to stand up to leave, Derek would stop her.

Before Derek could respond, there was another knock on the door. "Dr. Shepherd?" The doctor she remembered from the emergency room, Dr. O'Malley, poked his head in. "I have your test results."

Meredith's eyes could have killed George right where he stood. "You knew about this?!"

"I knew Dr. Shepherd was waiting on test results; that's all I knew. And now I'm leaving." Dr. O'Malley handed the envelope to Derek and quickly left the room, closing the door behind him.

"I can't believe you," Meredith sounded defeated. She sat down on the couch where Amelia had sat earlier, putting her head in her hands. "I absolutely cannot believe you, Derek."

"She cheated on me, Meredith. She slept with my best friend while we were still married. It isn't exactly something I like to bring up in casual conversation," Derek looked frustrated. All of his attention was on Meredith; it seemed like he'd forgotten Amelia was in the room.

"Wait… what?" Amelia furrowed her eyebrows and stood up from her spot on the floor. "She did what?" Addison was always so secretive about why she and Amelia's father weren't together anymore. Amelia had never known her father's name, much less the reason they weren't together anymore. "That's not true… that can't be true. She wouldn't do that."

"Amelia… there are things about your mother you don't know," He responded, still gripping the envelope in his hands.

"You're lying," She shook her head, feeling tears burning again. She was starting to get a migraine from all the emotions she was dealing with that day.

"Why would I lie?" He put the envelope down on his desk. "I have no reason to lie, Amelia. She cheated on me, and I left. I came here to start over. I didn't want to think about Addison, so I pretended she didn't exist. In my mind, the twelve years I was married to Addison didn't happen."

"So… you just stopped loving her? Stopped caring about her? You can't pretend someone doesn't exist. Not someone, you love… not someone you care about… if you did that to her, who's to say you don't do that to her?" Amelia pointed at Meredith. "What kind of a person are you?"

"That isn't fair," Derek shot back.

"Can you just open the envelope? All my life, I wanted to know you. I wanted to know who you were. Mom told me nothing about who you were. I knew some things... I knew I had your eyes. I knew I had your smile. I knew I got my obsession with ferry boats from you. She didn't act like you didn't exist! She does exist. She's a person. She matters. And at this point… I hope I'm not yours. I hope that DNA test says I'm not your kid. I'd rather not have a father than have someone so sadistic as my father." The tears were flowing freely now. Her hands were shaking, and she felt her breaths becoming more ragged. She knew she was going to have a panic attack. She could feel it, and the only person who knew how to bring her down from that was her mother. She sat down on the couch, keeping a few feet of distance between her and Meredith, who seemed stunned and silent from Amelia's outburst. Amelia focused on trying to control her breathing as Derek opened the envelope. She heard the paper being slid from the envelope and fought back every anxiety ridden feeling that was building up in her body. She needed to know. This wasn't just finding out who her father was; she was finding out who she was.

Derek's eyes met hers, then Meredith. "It's… they're positive. The DNA test results are positive."
