“Dr Mark!” Milo shouted and let go of Derek’s hand and ran over to Mark. Mark bent down and hugged him.

“I missed you Dr Mark”

“I missed you too kid. How was O’Malley’s house?”

“It was okay I guess”

“Hey” Derek said and walked over to them.

“Hey, so what have you been doing?” Mark asked the both of them.

“I met some of Derek’s patients” Milo smiled

“Sounds fun” Mark smiled, “So have you found out where babies come from yet?”

“Nope” Milo frowned. “All I know is that you need a man and a woman and that it comes from the mommy’s tummy and nothing else”

“So have you asked Derek?”

“You still haven’t given me an answer Derek” Milo frowned at Derek

“We’ll talk about it later”

“Okay, where’s my mom Dr Mark?”

“In surgery now, so you mister are coming with me unless your father wants to take you”

“Can I stay with Dr Mark Derek?” Milo asked. Derek nodded and Milo took Mark’s hands into his own.

“Stay with Yang okay” Mark said to Milo

“I know. Go back to work them” Milo said and pushed Mark. Mark smiled at him before walking off. Milo walked into the cafeteria and sat down at Cristina’s table.

“Aunt Cristina you’ll never lie to me right?” Milo asked and took a chip.

“Right… What do you want to ask me kid?” Cristina said looking up from her magazine.

“Where do babies come from?”

“Ah… I knew this was going to be asked soon. You should ask your father that”

“Why does everyone say that?” Milo frowned

“Because it’s something that needs to be done by a man” Cristina smirked

“But I’ve asked loads of people and they all told me different things” Milo sighed

“You want the truth?”

“Yeah!” Milo said lightening up.

“Well it’s something called sex”

“What’s that?” Milo frowned

“Are you sure you want to know?”

“Duh, that’s why I asked you silly. Adults are so silly” Milo giggled. Cristina couldn’t help but smile at how cute Milo was.

“You’ll always be my favourite kid you know”

“Well you’ll always be my favourite aunt” Milo smiled

“I’m better than Izzie”

“Yup” Milo nodded, “Now tell me what sex is”

“Wait how old are you again?”

“Seven and a half”

“Your too young”

“Am not. Tell me what sex is”

“Ask Mark, he loves sex” Cristina said and started laughing to herself.

“Fine!” Milo pouted

“Don’t pout at me young man” Cristina gasped

“Sorry” Milo giggled

“That’s better now let’s go find Mark and ask him. But don’t say you got sex from me okay”

“Okay. I’m getting closer to where babies come from” Milo smirked

“Yup”

Cristina had left Milo with Burke because she had to deal with her interns. Milo was following Burke whilst he looked through a chart.

“You’re a man right Dr Burke?” Milo said whilst they walked

“Indeed” Burked nodded.

“Then where do babies come from?”

“Well, you call us the baby service and you tell them you want a baby and the next day it arrives at your house” Burke said confidently

“You’re a bad liar Uncle Preston”

“You asked me where babies come from and I just told you”

“But how did they get in the mommy’s tummies?”

“Ah… well…” Burke stuttered because Milo had just out smarted him.

“Don’t worry, I’ve got half of the answer already. I’m gonna ask Dr Mark later” Milo grinned.

“Okay” Burke sighed.

“Are you and aunt Cristina gonna have a baby?”

“Maybe, but not just yet”

“Why not?”

“Because we are not ready yet, and if we do then we won’t be able to spoil our favourite little boy”

“Your right” Milo smiled, “You’re the best Uncle Preston”

“Thank you young man”

“Mommy!” Milo shouted and ran towards her when he saw he come out of the scrub room.

“I’ve missed you” Meredith said lifting him up.

“I’ve missed you too” Milo said

“Thanks for looking after him Burke” Meredith said looking over at Burke.

“No problem” Burke said and walked off.

“Had fun at Uncle George’s place?” Milo shrugged

“Let’s go. I’m starving”

They arrived at the cafeteria and they both brought food to eat and sat down at the table. Before they knew it, Mark had joined them at the table.

“Hello” Mark smiled

“Hi, Dr Mark I need to ask you something”

“Okay, go ask me” Mark nodded

“I have been told that you like sex” Milo started in a serious tone, Mark and Meredith both chocked and started laughing. “What’s sex Dr Mark?” Milo asked through their laughs.

“That’s… Oh… who told you?” Mark was finally able to say through the laughs.

“That’s a secret. So what’s sex?” Milo frowned and looked at them laughing, after a while they had both calmed down and Mark answered Milo’s question.

“Why do you want to know about sex, your too young”

“That’s how babies are made right?” Mark nodded, “Then what’s sex?”

“That’s an activity that adults do” Mark said and cleared his throat.

“what do you have to do?”

“Adult things. You don’t need to know, when your all grown up you see what it is”

“Have you and my mom had sex?” this made Mark and Meredith laugh again but they calmed down quicker than before.

“No” Mark lied.

“Is sex fun? Because you like to do fun things.” Milo shrugged

This made Mark laugh again but Meredith didn’t find it as amusing no more, her little boy was asking about sex. Mark looked over at Meredith and knew that she didn’t like the fact that Milo was talking about sex.

“I don’t know. Promise me one thing Milo” Mark started, “Don’t’ ever mention sex again okay”

“Why not?”

“Because it’s something that kids shouldn’t be saying okay”

“Okay, I promise” Milo promised
