What if Blair had made it to the Empire State Building on time? Flashback to Season 3.

Blair yanked the glass door open, glancing hastily at the time on her phone. 6:59. She had one minute to spare. Blair ran around the corner of the observation deck, not stopping till she saw him. He stood facing her, pink peonies in hand and a huge smile of relief flooding his face.

"Chuck," she murmured under her breath before running into his arms. She flung her arms around his neck, pressing her body flush against his. His arms tightened around her, pulling her closer, and he buried his nose deep within her hair.

"Dorota went into labor," Blair said, pulling back slightly to look at his face. "I almost didn't make it."

"But you're here. You came," he breathed. His hands reached for her face, brushing a stray curl aside.

"Every bone in my body tried to stop me. Every voice in my head screamed don't," she admitted.

"But?"

"But I didn't listen. I listened to my heart because," she looked straight at him then, "I love you," she breathed out. Chuck's breath rushed out of him then and absolute relief coursed through his veins. She was here. She loved him. He kissed her then, pressing his lips softly against hers. She smiled against his mouth and flung herself at him again. He laughed.

"Oh Chuck," she whispered. "I love you so much. I can't fight it anymore." She ran her fingers through the hair at the back of his neck. "I can't deny that our path has been complicated, but in the end love makes everything simple." She smiled softly.

"Yes, yes it does," he said, kissing her soundly. "Here," he said, handing her the pink flowers. "These are for you."

"My favorite," she smiled, shoving her nose into the bouquet. He pulled away from her ever so slightly and slid his hand into his coat pocket. His hand closed around the small velvet box concealed there.

"Blair," he said, suddenly looking very serious.

"Yes?" she answered, smiling still but furrowing her eyebrows slightly at his sudden seriousness.

"I know I've caused you a lot of pain," he started.

"Chuck…" she tried, but he shushed her.

"But I hope to make it up to you. Even if it takes me the rest of my life," he said and then quickly amended, "our lives." Deep within his pocket, his hand squeezed the small box once in reassurance. He took a deep breath before continuing. "Blair, I love you. So much. Nothing would make me happier than to spend the rest of our lives together." Blair's eyes widened as Chuck knelt down on one knee.

"Blair, would you do me the honor of becoming my wife?" His eyes searched for hers then. And then suddenly, her lips were on his. Her tongue probing his mouth, her hands reaching for his face. He laughed.

"Is that a yes?" She laughed too.

"Yes, yes, yes, yes, yes," she murmured over and over against his lips. "Yes, I would be honored," she said, pulling back to gaze into his eyes. He grinned, sliding the Harry Winston ring on her finger. She gazed down at the beautiful object.

"Oh Chuck, it's beautiful."

"One of a kind," he replied. "I had it designed especially for you."

"I love it." She wrapped her arms around his neck. "And I love you."

"I love you," he whispered back. "What do you say we get out of here?" he asked.

"You have any place particular in mind?" She grinned.

"Any place where we can officially celebrate," he kissed her. "Without interruptions," he finished, sealing the sentence with another slow kiss.

"Sounds wonderful," she smiled. He reached for her hand, entwining their fingers as they made their way back to Chuck's waiting limo. But before getting in the limo Blair stopped.

"Chuck," she said. "We're getting married," she whispered. He squeezed her hand.

"I know." They both grinned.
