Mark sighed and glanced at his watch anxiously. He didn't want to be late for his meeting with his new surgeon general in L.A. He took a peek at the long line in front of him and clutched his bags tighter.

"Mark!"

He spun around, looking for whoever was shouting his name. He already knew—that was the cause of the smile spreading on his lips.

"Mark!" called out Addie, pushing through the crowd. Mark spotted her and his face brightened, his heart skipping a beat. His beautiful angel.

"Mark," she murmured, flinging her arms around him without thought. She rested her head in his strong chest, letting his familiar and comforting smell soothe her. He looked a bit taken aback but quickly dropped his bags and put his arms around her, burying his face in her soft red hair.

"Chief just told me—after I refused to do surgery if he didn't," she explained, grinning. But her expression quickly turned worried, though. "Why didn't you tell me, Mark?"

He suddenly found looking at his shoes interesting. "I—I didn't want to let you convince me to stay."

She toyed with a strand of his hair, curling it with her fingers. "I was so worried when you didn't show up to work since we……fought." She gazed into his eyes, eyes she would sorely miss.

He looked away from her painful gaze, her blue eyes piecing his heart so."I'm sorry. For making you worried and for the fight. I shouldn't have—"

"Don't be," she said firmly. "It was my fault too, you know."

They stayed in an awkward silence, feeling people staring at them. Addie opened her mouth to break the ice but no words would come out of her mouth. Then, she suddenly remembered her purpose of coming.

"Mark," she began apprehensively. "That night, when you told me you love me…….is that true?"

He smiled, finally looking into her eyes. He caressed her hair lovingly. "Every moment."

She sighed deeply, mysterious fear filling her eyes. It was her turn to look away. "I need you to do something for me."

"Anything."

She swallowed painfully. "I want you to move on, find someone else."

He withdrew his hand, his face falling. He determinedly looked at anywhere but her. He realized that people behind him at the line moved without him and he didn't care at all. It hurt him that even thought he had already confessed his love for her, she still thought of it as a feeling that he could just whisk away. As if it was nothing to her.

She glanced at him, surveying the damage she caused. "Mark?"

"I'll try." He wondered how to stop loving her and just find another Addie; she was the only one who could ever make him feel that way.

His face tugged her heart and she bit her lip. "I don't want you to be pining for me all your life."

"Is that wrong?" he asked quietly. "To want someone you love to love you back?"

But it's time to face the truth,
I will never be with you.

No. She doesn't say it because she wants to spare him from further pain.

Last call for passengers of flight 46 Los Angeles

"That's me," he announced bitterly. He glanced at her, chiding himself for not noticing that she'd been crying all along . "Addie, I'm sorry. Please don't cry."

"No—it's not that," she sniffled. "I'm gonna miss you so much, Mark."

His look softened and he used his thumb to gently grazed her tears away. "I'm gonna miss you too. But please don't cry. At least now. You know I hate it when you cry."

"I can't help it, Mark," she responded, frustrated at her tears for flowing so freely. "Who's gonna tease me in the elevator and make me laugh?"

He tilted his head adorably. Addie just wanted to kiss him right then and there. "We'll see each other again. It's not like we won't ever meet each other again, anyway," he comforted her bravely though he was already blinking tears his off and his voice was cracked with emotion. "Besides, you need me and I'll just hop on the next plane to Seattle."

She smiled. "That's us, alright."

He laughed. "Yup. Transcontinental booty calls."

He leaned forward to kiss her on the cheek. Moving back, his lips accidentally touched hers and lingered there for some moments. She let him, blushing a bit because of the electricity running through her at that moment.

Mr. Mark Sloan: Last call for boarding

"I'm coming," he muttered angrily. "So…..good-bye for now."

"For now," she echoed. She watches as he picks his bags up and walks away. Away from her.

Then she turns into a sobbing mess, regretting the day she screwed Karev. Just one mistake led her to lose the only one who ever loved her. Truly.

Tears flowed down her cheeks freely, the pain of his leaving harder than she ever imagined it to be. So this must be how he felt, she thought.

"I love you, Mark," she whispered to no one. "I'm so sorry it took this long to realize that."

How do I breathe,
Without you here by my side?
How will I see,
When your love brought me to the light?
Where do I go,
When your heart's where I lay my head?
When you're not with me,
How do I breathe?
How do I breathe?
