Disclaimer: I do not own Grey's Anatomy.

A/N: I have 25,000 hits! Wow! Okay, on to what I was really going to say…This is the last chapter. I tried, I really did, to come up with more content to put in this story, but none of it worked out. It took me a while, but I realized that it was because the story I was trying to tell, of Addison and Derek after their divorce…that story was finished. Sure, I could write other stories…Addison and Derek: The Later Years. I'm just kidding, I would never ever name a story that, but do you get my point? There are other stories about them to tell, but none of them are this one. So, I leave you with this.

I also would like to thank everybody who read the story, especially those who reviewed. You have no idea how much it means to me that so many people took the time to sit down and read this story, let along to write a review. I would also like to thank everybody who added me to their favorites list, or this story to their favorites or alerts list. It is a really great feeling to know that somebody other than yourself enjoys what you've written. So, I have one last plea for everybody who has read this story, both those who have reviewed, and those that haven't. Since this is the last chapter, please review!

Epilogue: Inadvertent Humor

The sound of a pager beeping startled Addison out of her sleep. "I bet it's mine," a voice from behind her said, startling Addison. Turning over, Addison looked at Derek while struggling to remember how she had ended up in bed with him. After a second of frantic thinking, she remembered the events of the night before, and sighed in relief that she hadn't done something stupid.

Reaching for her pager, which she had placed next to the pillow she and Derek were sharing, she glanced at it, squinting from the light the pager was giving off. "No, it's mine," she mumbled, sitting up. For a moment she contemplated just laying back down and going back to sleep, but it took her only a moment to realize that that would not be wise. Should somebody die because she had been lazy, Addison knew she would never be able to forgive herself.

Addison slung her legs over the side of the bed, and jumped off of it. She put on her jacket and stuck her pager into it, taking a moment to examine herself. Her hair needed to be brushed, her clothes were wrinkled, and her pantyhose had a run. Running her hands through her hair to make it look more presentable, she quickly put her high heeled shoes on. Without looking at Derek, Addison made for the door.

"Addison—" Derek began, but stopped when Addison spun around to look at him.

"We'll talk later," she said briskly, before opening the door, glancing behind for once last look at Derek, and closing it. Willing herself not to think of Derek and what had happened the day before, she waited impatiently for the elevator, running her hands over her skirt to lessen the wrinkles in it that were the result of sleeping with her clothes on.

Once downstairs, Addison looked for Bailey, who had paged her. Finding her leaning against the nurses' station, Addison went up to her. "You paged?" she said, trying to sound enthusiastic.

"Leila Hendricks, thirty five, female, pregnant in two uteruses," Bailey said in one breath.

"Two uteruses?" Addison asked in disbelief, and Miranda nodded. "Well, this is the coincidence of the century," Addison commented absently, taking the chart from Miranda and looking it over carefully. "Two women pregnant in two uteruses come to Seattle Grace less than a year apart. How unlikely is that! Only, I'm going to hope that I don't have the pleasure of accidentally informing my patient's husband of my patient's infidelity again. Still, this must be some sort of statistical…"

"You are one of the best neonatal surgeons," Bailey cut off Addison. "The timing is a coincidence. I find it very unlikely, however, that they both just showed up at Seattle Grace, completely unaware that you are here and of your credentials, completely unaware of how rare their condition is, and the fact that you have a very strong record with high-risk pregnancies," Bailey finished dryly.

Addison blushed, embarrassed that she had not thought of that. Instead of justifying her mistake, Addison decided to pretend she had never made any comment. "I'm going to need an intern," she stated, looking up from the chart.

Bailey nodded. "Grey!" she called across the hall, causing a few people to look at her questioningly. Meredith turned away from her conversation with George and walked over to where Bailey and Addison were standing. "You're with Dr. Montgomery today," Bailey informed Meredith.

Unwilling to comprehend what she had just heard, Addison turned to stare at Bailey. Surely Miranda had known what had happened last night—Miranda never missed anything. "Dr…Dr. Grey?" Addison stuttered, staring at Bailey in confusion and anger.

"Dr. Montgomery—" Meredith stammered, looking at Bailey with an expression similar to that Addison was wearing. When Addison glanced at Meredith's face, she could tell that Meredith did not care for this assignment any more than she did.

Bailey looked from one woman to the other, an expression of annoyance on her face. "Do you two have a problem?" she questioned, her voice daring either of them to say anything other than, "no." Meredith looked at the floor abashed, but Addison remained staring at Bailey.

After a moment of awkward silence, Addison opened her mouth. "It's just that Dr. Grey has spent a lot of time in my service recently, and I think it might be best if she…"

"…If I broadened my horizons a little bet?" Meredith finished, relieved.

Bailey looked at Addison, then at Meredith, and then back to Addison. "Broaden your horizons?" Bailey said incredulously. "I'm sorry," she said eventually, her voice showing disbelief, though Addison knew that it was at least partially faked. "Is it not true that we all work in the same hospital?" Without waiting for either Addison or Meredith to say anything, she continued, "Good. So then, there is no problem here. It is a problem, though, that there is a patient waiting in exam room 3010 while her doctors argue over issues only important in their personal lives. Go." With that, Miranda turned around and walked away, leaving Addison and Meredith staring at her disappearing figure.

Addison cleared her throat, determined to make the best of a less-than-ideal situation. "Okay, Meredith, let's check on Mrs. Hendricks," she said, offering Meredith a small smile.

Two Months Later…

Addison strode into the elevator, holding hands with Derek, both laughing over something that had happened in New York, where Addison and Derek had been for the past two weeks. When Derek suggested that they go visit his newborn nephew, Addison had instantly agreed, insisting that they also stop at her parents "so that they will stop calling and asking if I have a new boyfriend."

"Morning, Meredith," Addison said brightly, as Meredith hurried to get in the elevator before the door closed.

For a moment Meredith looked at Addison, wondering what had precipitated Addison's good mood, but shrugged. Though it had taken her a while to admit it to herself, she liked Addison, and couldn't really begrudge her for being with Derek. Besides, there was someone else now… Tearing her thoughts away from her new boyfriend, Meredith smiled. "Good morning, Addison…Derek…" she replied.

There was silence for a moment, before Addison plunged on. "Has anything interesting happened since we've been gone?"

"You haven't heard?" Meredith asked incredulously, before remembering that Addison and Derek hadn't been at Seattle Grace in two weeks. The elevator door opened, and all got out. Meredith started to walk away, but Addison stopped her.

A little more warily than before, Addison asked, "Haven't heard what?"

"About Mark!" Meredith exclaimed, as if it was obvious.

Addison groaned, muttering, "Oh God, what has he done now?"

Meredith shook her head violently. "No, nothing like that…well, sort of like that, but I don't mind…" Addison and Derek sent Meredith a look asking her to tell them what was going on. "Mark…and Lexi…apparently they've been together for months now…nobody had any idea…he doesn't seem like the type to settle for being with just one person…" Meredith trailed off.

"You'd be surprised what Mark is capable of doing, should he want to," Addison said wryly, remembering an incident that had taken place when Mark was an intern involving a bet, scissors, purple hair dye, and ultimately ending in an extraordinarily expensive trip to the barbers. For a moment Addison almost shared the story with Meredith, but a moment's consideration made her decide to spare Mark the humiliation. A thought occurred to Addison suddenly, "Who's Lexi?" she asked.

"My half-sister!" Meredith exclaimed, her tone of voice once again suggesting that it was obvious.

Addison and Derek both groaned, exclaiming together, "Oh God." Addison shot Derek a look and suddenly both were on the brink of laughter. Meredith looked between both of them, but decided that she didn't mind and smiled too. "You know, if it bothers you I can speak to him about it…" Addison began, but Meredith shook her head.

"Actually, he seems quite fond of her." Meredith smiled, as if the notion of Mark settling down with anybody was laughable. A year ago, Addison would have been inclined to agree; however, now she was willing to believe that perhaps Mark was capable of such a feat.

Meredith looked around the hall, spotting somebody, and waving for the person to come over to where she, Addison, and Derek were standing. Addison blanched when she saw who Meredith had beckoned over. Trying to keep from blushing, Addison smiled and said, "Hello," albeit in a very distracted, shocked manner.

"Addison, Derek, I have somebody I'd like you to meet," Meredith formally introduced the man, then kissed him quickly on the cheek. "This is Steven." Addison tried desperately to regain her composure, painfully aware that she looked just as startled as she felt. Suddenly she laughed, though it would be minutes before Derek or Meredith understood why.

"This is ironic, isn't it?" she asked Steven, who nodded and started laughing too. And, for once, the shocking irony of it didn't bother Addison, and she was able to see the humor in all of it. Though that night, as she lay in bed next to Derek, thinking, she would wonder how they had all gotten that way, how all of their relationships had ended up so hopelessly tangled, in that moment all Addison could think of was how inadvertently funny it all was. And, amidst all of her laughter, for the first time ever Addison was able to think, and genuinely believe, that perhaps the events of the past two years had all happened for the better.
