A/N: Okay, this was probably my favorite chapter to write!!! Hope you like it!! Review please:)

Alex sat in the lobby with his hand under his chin, contemplating everything he had just discovered in a half an hour.

Izzie sat next to him. "Hey."

"Hey Iz…"

"You okay? About Meredith?"

"Um, yeah of course."

Izzie gave him a funny look. "Yeah right! I know you too well."

Alex looked up at Izzie and sighed. "I don't know. I'm just frustrated, you know? I mean she just left. It's like I didn't mean anything to her. It's like I was nothing. Then, she comes back with a 10 year old girl who looks exactly like her dad…I just, I don't know…"

"She betrayed you…"

"Yeah, in a way she did."

Izzie touched Alex's hand. "Alex, you don't have to hide the fact that you're upset. Let it out. Don't keep it all inside."

Alex smiled. "I swear, you dating a shrink has totally gotten to your head."

Izzie giggled. "Well I'm sorry but it's true!"

"Yeah, yeah I guess your right."

"I'm Izzie. I'm always right!"

"Except when you're wrong…"

"True."

Alex laughed then nudged her. "Thanks, Iz. I couldn't have gotten through everything without you."

"I know!"

Sarah sat in the cafeteria, her legs were brought up to her chest and she was humming the "Who Knew?" song from Pink. Derek noticed, smiled, then walked up to her.

"Hey."

Sarah took off her iPod earphones.

"Oh, hi, Dr…?"

"Shepherd."

"Oh right! I'm Sarah, Meredith's daughter."

"Yeah…it's funny though you don't really look like her."

"Yea, I know…my mom says I look like my dad but I've never met him."

"But your mom talks about him?"

"Rarely. I asked about him once, but my mom just made up some lame excuse that she had to work out. Mom NEVER works out."

"Would you like to meet your dad?"

Sarah nodded. "Yeah…but my mom and I are doing fine by ourselves so it's not like I need him or anything."

A pain struck through Derek's body, but what was he expecting: Sarah to miss him terribly and not only want him…but need him.

"Oh, I see."

"Dr. Shepherd, is it?"

"Yes."

"Can I ask you a question?"

"Sure, anything…"

"Do you have a dad?"

Derek stiffened. "I did."

"What happened?"

"He died when I was 12. He always told me that I would become a doctor one day because whenever a kid was sick in my neighborhood I always jumped to take care of them."

"How'd he die?"

"He was buying me a present for my 13th birthday, when some guy held the store hostage. My dad tried to get away but they shot him…I used to blame myself for what happened because I kept asking him if he got me a gift…"

"Oh gosh…I'm so sorry. That's horrible."

"Yeah, but I was glad I had a dad. Some of my friends never knew theirs."

Sarah looked down. "I don't know…maybe I'm mad at my dad."

"Why?"

"He didn't even come look for us…my mom and I."

"Well maybe he thought your mom didn't want him to."

"PLEASE! My mom checked the voice mailbox every half hour in case someone called! She was waiting for someone…I think my dad."

Derek sighed deeply then placed his hand on his head. "Wow."

"Yeah, I know…but maybe it's better if I never meet him. I might be awkward. And plus, my mom only needs me!"

Derek looked at Sarah then gave her a small smile. "But, maybe your dad wants to meet you." With that, he left…leaving Sarah wondering if what he said was true…
