He laid there next to his six month old baby girl, watching her sleeping form - the rise and fall of her tiny chest. It had been an horrific week as the infant fought against a fever and tortuous teething. Mark lay his hand upon her chest, it taking up her entire torso, and pressed a gentle kiss upon her forehead.

Callie watched him from the bedroom door unnoticed until a stifled "aw" escaped her. His blue eyes met her brown and she smiled.

"What are you doing here?" he whispered.

"Arizona got paged in." The ways she threaded her fingers through her hair told Mark something was off, but he let it go. "How is she?"

"Wasn't that bad tonight."

Callie crossed over, tip toeing to the bed. She sat down gently, watching as the infant was not disturbed. She smiled at Mark.

"That's good."

A comfortable silence fell between them as they watched their daughter sleep, small whispered snores escaping as her small hand moved against her mouth. It was her mother's mouth. Mark watched Callie as she slid her hand gently over the infants black curls and she too pressed a kiss to her forehead.

"I wish I could take this whole ordeal away from her," the Latina spoke, her eyes shifting to Marks.

He smiled back at her, knowing that it was what she needed. She never could manage to pull off a poker face. Her eyes always gave her away. And tonight, her smile tried to hide the bit of sadness in her chocolate pools.

"Another fight." Mark whispered. It wasn't a question, it was simply an acknowledgement.

Callie's shoulders lowered and she slowly released a breath before giving a helpless shrug. "I don't really know what to do. I've made it so I only see you when it's when your turn with Sofia or at work - and I barely see you there. Besides Sofia, I've made sure to put her first. I even go with her when she goes to Malawi just so she won't think…" Her voice trials off and she covers her mouth, looking away.

"Hey," Mark shift so that he sits up more, careful not to disturb the mini Latina.

Callie turns back to him. "It's just so easy with you."

His piercing blue eyes stayed glued to her beauty, a million different emotions swirling inside him. He had missed his friend, his soul mate but her happiness was always his priority. Her sadness made him curse himself because his constant need to make sure she was happy never left her that way. How many times has she cried on his shoulder? A thousand tears, a hundred shots, a dozen break downs and a broken nose later and Callie was still not as happy as she deserved.

"Maybe she knows," he said finally.

"What?"

"I could've had you, Callie. I could've had you and maybe she knows that."

Callie's eyes looked at him in confusion and her mouth, her beautiful mouth fell open as her 'what' was still written all over her face.

"After George, I wanted you and I waited. I waited so long that you started having feeling for Erica. I could've fought and made you see me but I wanted you to be happy so I let you go,"

"Mark-"

"You mean everything to me and the way we are right now - you, me and Sofia - I got to bed wishing for it."

Callie swallowed and moved her eyes to her daughter. The daughter that was theirs.

"I'm just saying that she sees that." Mark leaned back, finally unburdened with the truth.

Callie mimicked Mark, leaning back against the bedrail as well. She looked at him.

"Thank you, " she said. He looked at her in surprise. She leaned over planting a simple kiss on his lips. "You know I love you, right?"

"Yeah."

"I guess I never thought about it."

"Thought about what?"

"That I could've had you, too."
