"What a day…" Derek sighed as he pressed the zero button in the elevator, headed to ground floor.

"I know…" Meredith added, as she took hold of her boyfriend's hand and leaned in closer, "listen, we could get some wine, Chinese food, relax on my sofa… or embark on," she whispered as she leaned in closer, "other extracurricular activities," she said with a smile.

"Now that sounds just perfect," he told her as leaned in and met her lips for a quick but sweet kiss.

The elevator door opened to reveal Dr. Miranda Bailey staring at the happy couple, and immediately changed her facial expression and crossed her arms across her chest.

"Ah! Now what did I tell you about keeping private relations away from this hospital?!"

Derek and Meredith immediately broke apart and smiled at her, "Good night Dr. Bailey," Derek told his beloved colleague with a smile, before he and Meredith walked past her hand in hand.

"I'm watching you, Shepherd!" Miranda called out to him, as she observed them walking away hand in hand before she entered the elevator herself.

They turned round the corner, headed to the front doors, eager to head home after a tough shift. Derek was lost smiling at Meredith and actively listening to her chatting away, when he unintentionally looked forward, then looked again. He stopped.

"what's wrong?" Meredith asked her boyfriend as she stopped as well. She looked ahead to see a woman approaching them. But she was confused what was it about her that scared Derek so much.

They saw this red-haired woman walking through the doors, indeed walking towards them, in her high heels and beautiful buttoned trench coat.

"Ah! I was hoping I'd run into you! Missed me much?" this woman added with a smile.

"What the hell are you doing here?" Derek asked, changing his tone, while letting go of Meredith's hand.

"I'm sorry who are you?" Meredith asked the stranger.

"Oh sorry! Where are my manners?" she added sarcastically, "Addison Shepherd… and you must be the woman who has been sleeping with my husband!" she told Meredith to her face, as she awkwardly shook her hand, "Word gets round… talk about small world!" Addison blabbed about.

"I said… what are you doing here?!" Derek asked Addison furiously, looking her in the eyes.

"Richard needs me… well... I am a world-known neonatal surgeon!" Addison bragged, "I have to run I'm afraid, Derek honey, we'll catch up later okay? And it was nice to see you in person," she added sarcastically to Meredith, before she walked past them to walk away.

Meredith just stood there, stunned at what she just heard. She then looked at Derek, feeling her eyes suddenly swelling up with tears.

"I can explain…" Derek uttered, trying to hold her hand.

"Don't… just don't…" Meredith said, almost crying, as she made a run to the doors, heading outside for fresh air.

"Meredith! Wait!" Derek called out to her, trying to catch up with her.

"Fine!" Meredith yelled as she stopped and turned around, "explain to me how you have a wife and didn't care to even bring it up this whole time we were together?"

"My marriage was over before I came to Seattle! It was the reason why I moved out here! She slept with my best friend, I couldn't stand to look at her! I didn't think she would actually come and find me!" Derek tried to justify himself.

"Oh right! So that gives you the right to leave that big part of your life out of our relationship? Has it ever occurred to you how this could affect us? Or… convenient, isn't it? Having a bit of Meredith on the side?" Meredith yelled at him furiously as she turned to walk away.

Derek reached out to her and grasped her arm firmly, "Meredith!"

"Let go of me!" she yelled back at him, "I can't even look at you right now!" she told him, crying and turned to run towards her car.

Derek just stood there holding his briefcase, watching his beloved sweetheart walk away.

…

The next morning, Derek was a complete mess. He didn't sleep at all during the night. He couldn't sleep knowing he potentially lost every chance he had to be with Meredith.

He walked hurriedly to the elevator and as the doors opened, he spotted Meredith in the lift, while two nurses walked out. He stepped inside to meet her side, while Meredith looked away to avoid him. None of them said a word.

The doors opened and Meredith hurriedly walked out of the elevator. Derek decided to try and reach her. But as he took a turn from the elevator, he bumped into someone, causing all the files she was holding to scatter around on the floor.

"Derek! Watch where you're going!" Addison yelled at him, as she knelt to pick her stuff from the floor. Derek knelt down to help her, but was left astonished when he handed her the last file and both of them stood up straight.

He couldn't help notice she was wearing an unbuttoned lab coat to reveal a nice, small bump on her lower abdomen, through her blouse.

"You're… um…" Derek uttered as he held out his hand.

"Pregnant! Yes!" Addison exclaimed, "Did I not mention this was another reason why I came here? Congratulations, daddy!" she smiled at him, playing it cool.

Derek couldn't believe what he just heard. He took hold of her arm and pulled her towards him, "we need to talk! Let's go!"

"Ow, Derek! Fine!" she told him as she shrugged him off and walked away with him.
