"Okay kids," Alex called. "Mac and Cheese is ready."

All he got in response was giggles and thumps on the floor. He made a face.

"What are you two up to?" He walked into the living room to see the twins going down the stairs on their butt. He chuckled. "Are you too hungry?"

They looked up at him and shook their heads.

"Fun," They said at the same time and walked back upstairs. They reached the top and sat down before pushing off.

"Okay, okay. Just a few more…" The door bell rang cutting him short. "Then you two have to eat the food I slaved over." He walked to the door and opened it.

He would have never expected what he saw on the other side of that door. His eyes were wide in surprise and his mouth had fallen open slightly. The kids ran up and stood on either side of him. They started to tug on his shirt trying to get his attention. He looked down at them then up again.

"Kids, go play." He said, his eyes not leaving outside.

"Food," Zach said.

"One minute. Okay?" The kids ran off again. "What are you doing here, Mark?"

Mark looked back up at Alex.

"You have kids?" He asked quietly.

"No," That was all the information he would give up about Zach and Brookie with out Meredith's okay. "What are you doing here, Sloan?"

"What do you think?"

"You can't just waltz in and out of her life when ever you feel like it."

"Food," Zach said again.

"Go into the kitchen. I'll be right there." He didn't want Mark to see too much of them. He was aware of the strong resemblance between them and their father.

"I don't want to waltz in and out of it." He said. "I know you hate me and I'm sure Meredith does too. And I know it's been three years, but I made a mistake."

"Why aren't you telling her this?"

"Is she here?"

"She doesn't live here anymore. Once she came back to Seattle she brought her own house. But, she's at the hospital now."

"What do you mean 'came back to Seattle', Alex?"

"Just talk to her, okay? Talk to her and if you fuck with her again… and if you fuck with her again, I will personally go to your house and fuck your face up." He threatened.

"I don't want to hurt her."

"You've already done that. And do me a favor…"

"What?"

"Don't do this at the hospital. Don't make her see you there. She has patients to think about."

"I won't."

He stepped back into the house and shut the door.

"One second kids." He called and pulled out his phone. He dialed Meredith's cell number and waited while it rang.

"Hello?"

"Meredith?"

"Alex? Are the kids okay?"

"Yeah they're fine."

"I'm really busy right now."

"Meredith, Mark's back."

It seemed like all feel silent on the other end. He couldn't hear anything. No motion or breathing just the silence of air.
